CHAPTER 1

INTRODUCTION

Introduction to Project

Online news portal allows customers to read up to date news related to many fields like

entertainment, national, international, business, sports etc. without any payment or login.

He can also contact us to give suggestions and can also give us feedback related to our site.

New News can be added only by the admin and only admin have the right to update or delete

any News. Admin have the right to give authority to other for news update, add or

Delete.

The traditional media rooms all around the world are fast adapting to the new age technologies.

This marks the beginning of news portals by media houses across the globe. This new media

channels give them the opportunity to reach the viewers in a shorter span of time than their print

media counterparts.

MODULES

User

A user can directly read any type of news related to any field like entertainment, sports, business,

national, international etc. without login and also contact us or can give suggestions and

feedback.

Admin

Admin is the one who have the authority to see all the users feedback into the website. He can

register new accounts and also delete or update accounts. It means he have the authority tohandle the whole website. He can update, add or delete any news relate to any field.

Advantages

News on the Internet can be updated round the clock so that readers can have the mostup-to-date news any time of the day or night.

Once a news item is put on the Internet, it becomes instantly available for use round theglobe without additional variable costs.

The lead time required between occurrence of an event and news making on it availableon the Internet has reduced considerably. Some items of news like stock market prices

are now available almost in real-time.

News provider can get detailed data on popularity of news items. This information canhelp in better choice of information put on the site.

The type of news and the way it is presented can be customized to the needs andpreference of individual readers

You don't have to wait for newspaper in morning. Any time any news related to different fields will be available. Money and time will also save.

Disadvantages

Newspapers are more convenient to read. One can easily relax, reclined over a deckchair, and reading a newspaper. This Kind of ease in reading is not possible with Internet-news.

Newspaper can be carried and read at any location of the world. There is no preconditionof availability of Internet connectivity.

Newspaper can be carried and read at any location of the world. There is no preconditionof availability of Internet connectivity.

Reading newspaper does not require any equipment such as a computer. It is important to note that Internet capabilities are improving very fast, and with that the

Internet-news is moving toward overcoming its current disadvantages over newspaper.

TECHNOLOGY USED

Technology Used:

PHP, MySql, HTML, Javascript.

2.1 Front End:

PHP, HTML, Javascript.

2.2 Back End:

MySql.

PHP

PHP is a programming language designed to generate web pages interactively on the computer

serving them, called a web server. Unlike HTML, where the web browser uses tags and markup

to generate a page, a PHP code runs between the requested page and the web server, adding to

and changing the basic HTML output.

While PHP is great for developing web functionality, it is not a database. The database of choice

for PHP developers is MySQL, which acts like a filing clerk for PHP-processed user

information. MySQL automates the most common tasks related to storing and retrieving specific

user information based on your supplied criteria.

MySQL is easily accessed from PHP, and theyre commonly used together as they work well

hand in hand. An added benefit is that PHP and MySQL run on various computer types and

operating systems.

Birth of PHP

PHP grew out of a need for people to develop and maintain web sites containing dynamic client-

server functionality. In 1994, RasmusLerdorf created a collection of open source Perl scripts for

his personal use, and these eventually were rewritten in C and turned into what PHP is today.


5/38

The real beauty of PHP is its simplicity coupled with its power, as well as it being an interpreted

language, rather than a compiled one.

Compiled languages create a binary .exe file, while interpreted languages work directly with the

source code when executing as opposed to creating a standalone file.

Why PHP?

PHP runs on different platforms (Windows, Linux, Unix, etc.) PHP is compatible with almost all servers used today (Apache, IIS, etc.) PHP is FREE to download from the official PHP resource: www.php.net PHP is easy to learn and runs efficiently on the server side

What is PHP?

PHP stands for PHP: Hypertext Preprocessor PHP is a server-side scripting language, like ASP PHP scripts are executed on the server PHP supports many databases (MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL,

Generic ODBC, etc.)

PHP is an open source software

PHP is free to download and useWhat is a PHP File?

PHP files can contain text, HTML tags and scripts PHP files are returned to the browser as plain HTML PHP files have a file extension of ".php", ".php3", or ".phtml"

What is MySQL?

MySQL is a database server MySQL is ideal for both small and large applications MySQL supports standard SQL


6/38

MySQL compiles on a number of platforms MySQL is free to download and use.

Birth of MySQL

MySQL was developed in the 1990s to fill the ever-growing need for computers to manage

information intelligently. The original core MySQL developers were trying to solve their needs

for a database by using mSQL, a small and simple database. It became clear that mSQL couldnt

solve all the problems they wanted it to, so they created a more robust database that turned into

MySQL.

MySQL supports several different database engines. The database engine determines how

MySQL handles the actual storage and querying of data. Because of that each storage has its ownset of abilities and strengths. Over time, the database engines available are becoming advanced

and faster. For general web-driven tasks, the default MyISAM database engine works perfectly

fine.

Advantages of Using PHP with MySQL

PHP combined with MySQL are cross-platform (you can develop in Windows and serveon a Unix platform).

PHP and MySQL work well together.The programming interfaces between them arelogically paired up.

PHP and MySQL have open source power. PHP and MySQL can both be used for free.MySQL client libraries are no longer bundled with PHP.

PHP and MySQL are fast. Their simplicity and efficient design enables faster processing. PHP and MySQL dont bog you down with unnecessary details.

2.3About PHP5Only time will tell if the PHP 5 release will be as successful as its two predecessors


7/38

(PHP 3 and PHP 4). The new features and changes aim to rid PHP of any weaknesses it may

have had and make sure that it stays in the lead as the worlds best web-scripting language.

However , if you are familiar with PHP 4 and are eager to know what is new in PHP 5.

2.4 Language Features

New Object-Oriented ModelAdded the object-oriented syntax back in the days of PHP 3, it was added as syntactic sugar

for accessing collections. The OO model also had support for inheritance and allowed a

class (and object) to aggregate both methods and properties, but not much more. When Zeev

and Andi Gutmans rewrote the scripting engine for PHP 4, it was a completely new engine; it

ran much faster, was more stable, and boasted more features. However, the OO model first

introduced in PHP 3 was barely touched. Although the object model had serious limitations,

it was used extensively around the world, often in large PHP applications. This impressive

use of the OOP paradigm with PHP 4, despite its weaknesses, led to it being the main focus

for the PHP 5 release.

For example:

class Person {var $name;

function getName()

{

return $this->name;

}

function setName($name)

{

$this->name = $name;

}

function Person($name)

{

$this->setName($name);


8/38

}

}

function changeName($person, $name)

{

$person->setName($name);

}

$person = new Person("Andi");

changeName($person, "Stig");

print $person->getName();

public/ private/ protected access modifiers for methods and properties. Allows theuse of common OO access modifiers to control access tomethods and properties:

class MyClass {

private $id = 18;

public function getId() {

return $this->id;

}

}

Interfaces: Gives the ability for a class to fulfill more than one is-a relationships. A classcaninherit only from one class, but may implement as many interfaces as it wants:

interface Display {

function display();

}

class Circle implements Display {

function display() {

print "Displaying circle\n";

}

}


9/38

Instance of operator: Language-level support for is-a relationship checking. The PHP 4is_a()functionis now deprecated:

if ($obj instanceof Circle) {

print '$obj is a Circle';

}

Static methods.You can now define methods as static by allowing them to be called from non-object context.

Static methods do not define the $this variable

because they are not bound to any specific object:

class MyClass {

static function helloWorld() {

print "Hello, world";

}

}

MyClass::helloWorld();

Static members.Class definitions can now include static members (properties) that are accessible via the class.

Common usage of static members is in the Singleton pattern:

class Singleton {

static private $instance = NULL;

private function __construct() {

}

static public function getInstance() {

if (self::$instance == NULL) {

self::$instance = new Singleton();

}

return self::$instance;


10/38

}

}

Exception handling.PHP 5 adds the ability for the well-known try/throw/catch structured exception-handling

paradigm. You are only allowed to throw objects that inherit from the Exception

class:

class SQLException extends Exception {

public $problem;

function __construct($problem) {

$this->problem = $problem;

}

}

try {

...

throw new SQLException("Couldn't connect to database");

...

} catch (SQLException $e) {

print "Caught an SQLException with problem $obj->problem";} catch (Exception $e) {

print "Caught unrecognized exception";

}

foreach with references.In PHP 4, you could not iterate through an array and modify its values. PHP 5 supports this by

enabling you to mark the foreach() loop with the & (reference) sign, which makes any values

you change affect the array over which you are iterating:

foreach ($array as &$value) {

if ($value === "NULL") {


11/38

$value = NULL;

}

}

2.5HTML EmbeddingPHP can be written in HTML tags. We start php with a delimiter . For example

Sample PHP Script

The following prints "Hello, World":

2.6CommentsWe can write comments three different ways:

C way/* This is a C like comment

* which can span multiple

* lines until the closing tags

*/

C++ way// This is a C++ like comment which ends at the end of the line

Shell way# This is a shell like comment which ends at the end of the line

2.7Variables


12/38

Variables in PHP are preceded with a $ sign, and similar to most modern languages, they can

start with a letter (A-Za-z) or_(underscore) and can then contain as many alphanumeric

characters and underscores as you like. Examples of variable names include $count, $_Obj,

$A123. The following code example uses variables:

$PI = 3.14;

$radius = 5;

$circumference = $PI * 2 * $radius; // Circumference =pie* d

2.8 Managing Variables

Three language constructs are used to manage variables.

2.8.1 isset()

isset() determines whether a certain variable has already been declared by PHP. It returns a

boolean value true if the variable has already been set, and false otherwise, or if the variable is

set to the value NULL

.

Consider the following script:

if (isset($first_name)) {

print '$first_name is set';

}

This code snippet checks whether the variable $first_name is defined. If $first_name is defined,

isset() returns true, which will display ' $first_name is set. ' If it isnt, no output is generated.

2.8.2 unset()

unset() undeclares a previously set variable, and frees any memory that was used by it if no

other variable references its value. A call to isset() on a variable that has been unset() returns

false.

For example:

$name = "John Doe";

unset($name);

if (isset($name)) {

print $name is set';


13/38

}

This example will not generate any output, because isset() returns false.

2.8.3 empty()

empty() may be used to check if a variable has not been declared or its value is false. This

language construct is usually used to check if a form variable has not been sent or does not

contain data. When checking a variables truth value, its value is first converted to a Boolean

according to the rules in the following section, and then it is checked for true/false.

For example:

if (empty($name)) {

print 'Error: Forgot to specify a value for $name';

}

This code prints an error message if $name doesnt contain a value that

evaluates to true.

2.9 Datatypes

Eight different data types exist in PHP, five of which are scalar and each of the remaining three

has its own uniqueness.

2.9.1 Integers

Integers are whole numbers and are equivalent in range as your C compilers long value. On

many common machines, such as Intel Pentiums, that means a 32-bit signed integer with a range

between 2,147,483,648 to +2,147,483,647. Integers can be written in decimal, hexadecimal

(prefixed with 0x), and octal notation (prefixed with 0), and can include +/- signs.

2.9.2 Floating Point Numbers

Floating-point numbers(also known as real numbers) represent real numbers and are equivalent

to your platform C compilers doubledata type. On common platforms, the data type size is 8

bytes and it has a range of approximately 2.2E308 to 1.8E+308. Floating-point numbers include

a decimal point and can include a +/- sign and an exponent value. Examples of floating-point

numbers include 3.14, +0.9e-2, etc.


14/38

2.9.3 Strings

Strings in PHP are a sequence of characters that are always internally nullterminated. When

writing string values in your source code, you can use double

quotes ("), single quotes (') or here-docs to delimit them.

Double Quotes Examples for double quotes:"PHP: Hypertext Pre-processor"

"GET / HTTP/1.0\n"

"1234567890"

Single Quotes In addition to double quotes, single quotes may also delimit strings.However, in contrast to double quotes, single quotes do not support all the double quotes

escaping and variable substitution

Examples:

'Hello, World'

'Today\'s the day'

2.9.4 Booleans

A Boolean value can be either true or false. Boolean is probably the type that other types are

most often converted to behind the scenes. This is because, in any conditional code such as ifstatements, loops, and so on, types are converted to this scalar type to check if the condition is

satisfied. Also, comparison operators result in a Boolean value. Consider the following code

fragment:

$numerator = 1;

$denominator = 5;

if ($denominator == 0) {

print "The denominator needs to be a non-zero number\n";

}

The result of the equal-than operator is a Boolean; in this case, it would be false and, therefore,

the if() statement would not be entered.

2.9.5 Arrays


15/38

An array in PHP is a collection of key/value pairs. This means that it maps keys (or indexes) to

values. Array indexes can be either integers or strings whereas values can be of any type

(including other arrays).

2.9.5.1 array() construct Arrays can be declared using the array() language construct, which

generally takes the following form (elements inside square brackets, [], are optional):

array([key =>] value, [key =>] value, ...)

The key is optional, and when its not specified, the key is automatically assigned one more than

the largest previous integer key (starting with 0). Heres an example of a nested array()

statement:

array(array("name" => "John", "age" => 28), array("name" => "Barbara", "age" => 67))

2.9.5.2 Accessing Array Elements Array elements can be accessed by using the $arr[key]

notation, where key is either an integer or string expression.

2.9.5.3 Reading array values You can use the $arr[key] notation to read array values. The next

example build on top of the previous example:

print $arr2["name"];

if ($arr2["age"] < 35) {

print " is quite young\n";

}

This example prints

John is quite young

2.10 Operators

PHP contains three types of operators: unary operators, binary operators, and one ternary

operator.

2.10.1 Binary Operators

2.10.2 Numeric Operators All the binary operators (except for the concatenation operator) work

only on numeric operands. If one or both of the operands are strings, Booleans, nulls, or


16/38

resources, they are automatically converted to their numeric equivalents before the calculation is

performed

(according to the previous table).

2.10.3 Concatenation Operator (.) The concatenation operator concatenates two strings. This

operator works only on strings; thus, any non-string operand is first converted to one. The

following example would print out "The year is 2000":

$year = 2000;

print "The year is " . $year;

The integer $year is internally converted to the string "2000" before it is concatenated with the

strings prefix, "The year is".

2.10.4 Assignment Operators

Assignment operators enable you to write a value to a variable. The first operand (the one on

the left of the assignment operator or l value) must be a variable. The value of an assignment is

the final value assigned to the variable;for example, the expression $var = 5 has the value 5 (and

assigns 5 to $var).

Operator Name Value

+ Addition The sum of the two operands.

- Subtraction The difference between the two operands.

* Multiplication The product of the two operands.

/ Division The quotient of the two operands.

% Modulus Both operands are converted to integers. The result

is the remainder of the division of the first operand

by the second operand

In addition to the regular assignment operator =, several other assignment operators are

composites of an operator followed by an equal sign. These composite operators apply the

operator taking the variable on the left as the first operand and the value on the right (the r value)

as the second operand, and assign the result of the operation to the variable on the left. For

example:


17/38

$counter += 2; // This is identical to $counter = $counter + 2;

$offset *= $counter;// This is identical to $offset = $offset * $counter;

The following list show the valid composite assignment operators:

+=, -=, *=, /=, %=, ^=, .=, &=, |=, =

2.10.5 Comparison Operators

Comparison operators enable you to determine the relationship between two operands.

When both operands are strings, the comparison is performed lexicographically.The comparison

results in a Boolean value.

Operator Name Value

== Equal to Checks for equality between two arguments

performing type conversion when necessary:

1 == "1" results in true

1 == 1 results in true

!= Not equal to Inverse of ==.

> Greater than Checks if first operand is greater than second

< Smaller than Checks if first operand is smaller than second

>= Greater than or Checks if first operand is greater or equal to second

equal to


18/38

Logical operators first convert their operands to boolean values and then perform the respective

comparison.

Operator Name Value

== Equal to Checks for equality between two arguments

performing type conversion when necessary:

1 == "1" results in true

1 == 1 results in true

!= Not equal to Inverse of ==.

> Greater than Checks if first operand is greater than

second

< Smaller than Checks if first operand is smaller than

second

>= Greater than or Checks if first operand is greater or equal to

equal to second


19/38

theyre not. You can add an else branch to an if statement to execute code only if all the truth

expressions in the if statement evaluated to false:

if ($var >= 50) {

print '$var is in range';

} else {

print '$var is invalid';

}

2.11.3 Switch Statements

switch (expr){

case expr:

statement list

case expr:

statement list

...

default:

statement list

}

switch (expr):

case expr:

statement list

case expr:

statement list

...

default:

statement list

endswitch

2.12 Loop Control Structures

Loop control structures are used for repeating certain tasks in your program, such as iterating

over a database query result set.


20/38

2.12.1 while loops

while loops are the simplest kind of loops. In the beginning of each iteration, the wh iles truth

expression is evaluated. If it evaluates to true, the loop keeps on running and the statements

inside it are executed. If it evaluates to false, the loop ends and the statement(s) inside the loop is

skipped. For example, heres one possible implementation of factorial, using a while loop

(assuming $n contains the number for which we want to calculate the factorial):

$result = 1;

while ($n > 0) {

$result *= $n--;

}

print "The result is $result";

while (expr)

statement

while (expr):

statement list

endwhile;

2.12.2 do...while Loops

do

statement

while (expr);

The do...while loop is similar to the previous while loop, except that the truth expression is

checked at the end of each iteration instead of at the beginning. This means that the loop always

runs at least once. do...while loops are often used as an elegant solution for easily breaking out of

a code block if a certain condition is met. Consider the following example:

do {

statement list

if ($error) {

break;

}


21/38

statement list

} while (false);

Because do...while loops always iterate at least one time, the statements inside the loop are

executed once, and only once. The truth expression is always false. However, inside the loop

body, you can use the break statement to stop the execution of the statements at any point, which

is convenient. Of course, do...while loops are also often used for regular iterating purposes.

2.12.3 for Loops

PHP provides C-style for loops. The for loop accepts three arguments:

for (start_expressions; truth_expressions; increment_expressions)

Most commonly, for loops are used with only one expression for each of the start, truth, and

increment expressions, which would make the previous syntax table look slightly more familiar.

The start expression is evaluated only once when the loop is reached.

Usually it is used to initialize the loop control variable. The truth expression is evaluated in the

beginning of every loop iteration. If true, the statements inside the loop will be executed; if false,

the loop ends. The increment expression is evaluated at the end of every iteration before the truth

expression is evaluated. Usually, it is used to increment the loop control variable, but it can be

used for any other purpose as well. Both break and continue behave the same way as they do

with while loops. continue causes evaluation of the increment expression before it re-evaluates

the truth expression.

for (expr, expr, ; expr, expr, ; expr, expr, )

statement

for (expr, expr, ; expr, expr, ; expr, expr, ):

statement list

endfor;

SYSTEM DESIGN

3.3 System Requirements

Requirements regarding the installation of PHP Environment has been listed below

WAMP Server

WAMP is a form of mini-server that can run on almost any Windows Operating System.

WAMP includes Apache 2, PHP 5 (SMTP ports are disabled), andMySQL(phpMyAdmin and

SQL item manager are installed to manage your databases) preinstalled.An icon on the taskbar

tray displays the status of WAMP, letting you know if; a) WAMP is running but no services are

opened (the icon will appear red), b) WAMP is running and one service is opened (the icon will

appear yellow) or c) WAMP is running with all services opened (the icon will appear white).

Apache and MySQL are considered to be services (they can be disabled by left-clicking on the

taskbar icon, guiding your cursor over the service you wish to disable and selecting "Stop

Service").

The files/web pages that are hosted on your WAMP server can be accessed by typing

http://localhost/ or http://127.0.0.1/ in the address bar of your web browser. WAMP must be

running in order to access either of the above addresses.

If you would like to share your files/web pages with others, click on the icon located on your

taskbar tray and select "Put Online." You must have access to the Internet in order to continue.

Send the people that you would like to give access to the files/web pages hosted on your WAMP

server IP Address. Your can find your IP address here:
