PHP (Hypertext Preprocessor)Simple and powerful SSSLDynamic web pages.PHP scripts are executed on the serverPHP files have a file extension of ".php", ".php3",
or ".phtml".
PHP Introduction
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
Can be placed any where within a document.PHP is easy to learn and runs efficiently on the
server side
Why PHP
Server Side ScriptingCan be used from a command line interfaceEspecially suited for web developmentCan be embedded into HTMLRuns on a web serverCan be deployed on most web serversSupports almost every operating system and
platform free of charge.
PHP Features
<?php echo ”HELLO PHP”; ?>OR<? echo “HELLO PHP”
?>
Basic PHP program structure
How PHP works?

(scanning continues
untill <?php is
encountered)

Web Browser
SERVER
OUTPUT
PHP variables must begin with a “$” signCase-sensitive ($Foo != $foo != $fOo)Global and locally-scoped variables
Global variables can be used anywhereLocal variables restricted to a function or class
Certain variable names reserved by PHPForm variables ($_POST, $_GET)Server variables ($_SERVER)Etc.
Variables in PHP
Function headers are of the format
Note that no return type is specifiedUnlike variables, function names are not case
sensitive (foo(…) == Foo(…) == FoO(…))
Functions
function functionName($arg_1, $arg_2, …, $arg_n)
Sessions store their identifier in a cookie in the client’s browser Every page that uses session data must be proceeded by the
session_start() function Session variables are then set and retrieved by accessing the
global $_SESSION[]
Ex :-
<?php session_start(); if (!$_SESSION["count"]) $_SESSION["count"] = 0; if ($_GET["count"] == "yes") $_SESSION["count"] = $_SESSION["count"] + 1; echo "<h1>".$_SESSION["count"]."</h1>";?>
PHP Sessions
MySQL is the most popular open source Database server.
MySQL is developed by SUN Microsystems.MySQL is a Database and defines structure for
storing information.MySQL can retrieve data from Database.MySQL can Insert, delete & update records in
a database.
MYSQL (Database server)
In PHP, connection is established using the mysql_connect() function.
Syntax mysql_connect(servername,username,password); Ex :- <?php $con = mysql_connect("localhost",“root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } // some code ?>
Connecting To MySQL
• The connection is closed as soon as the script ends. To close the connection use the mysql_close() function.
Eg. <?php $con = mysql_connect("localhost",“root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } // some code mysql_close($con); ?>

JOB PORTAL WEBSITE PROJECT
Objective & ScopeProblem DefinitionSystem Analysis & Design Hardware and Software Data Flow DiagramTESTING
JOB PORTAL WEBSITE PROJECT
Objective The purpose of designing the online job portal
is to give the job seekers a platform for finding a right and a satisfactory job according to their qualification. It also connects the job seekers with the major agencies
Scope
The scope of the online job portal includes The Online job Portal System that is to be developed provides the members with jobs information, online applying for jobs and many other facilities. The basic scope of the project is given as under
Job Seekers Area Agency's Area Administrator's panel
Objective & Scope
An Online Job Portal where the job seekers can register themselves at the website and search jobs which are suitable for them where as the employers register with the website and upload jobs which are vacant at their company.
Viewing available jobs, or applying for the job at the agency can be done for which job seekers has to go to the agency and check the available jobs at the agency. Job seekers check the list of jobs available and apply the job. Then the agency will show available jobs for the job seeker for his qualifications and then updates the jobs database
Problem Definition
System development life cycle
The System Development Life Cycle framework provides system designers and developers to follow a sequence of activities. It consists of a set of steps or phases in which each phase of the SDLC uses the results of the previous one. A Systems Development Life Cycle (SDLC) adheres to important phases that are essential for developers, such as planning, analysis, design, and implementation, and are explained in the section below. A number of system development life cycle (SDLC) models have been created: waterfall, fountain and spiral build and fix, rapid prototyping, incremental, and synchronize and stabilize. The oldest of these, and the best known, is the waterfall model: a sequence of stages in which the output of each stage becomes the input for the next.

The DFD takes an input process output view of a system. That
is data objects flow into the software is transformed by
processing elements, and resultant data injects flow out of the
software. The purpose of the DFD is to provide a semantic
bridge between users and semantic developers.
Similarly database design depicts the various tables that are
created according to the system to be developed. Theses tables
are collection of intenerated data organized in tabular form.

Before actually implementing the new system into operations, a test run of tile system is done removing all the bugs, if any. It is all important phase of a successful system. After codifying the whole programs of the system, a test plan should be developed and run on a given set of test data. The output of tile test run should match the expected results. Unit test: When tile programs have been coded and compiled and brought to working conditions, they must be individually tested with the prepared test data. Any undesirable happening must be noted and debugged (error connections).
