    PHP 5 Syntax

    The PHP script is executed on the server, and the plain HTML result is sent back to the browser.

    Basic PHP SyntaxA PHP script can be placed anywhere in the document.

    A PHP script starts with :

    The default file extension for PHP files is ".php".

    A PHP file normally contains HTML tags, and some PHP scripting code.

    Below, we have an example of a simple PHP file, with a PHP script that uses a built-in PHP function "echo" to output thetext "Hello World!" on a web page:

    Example

    My first PHP page

    Run example

    Note: PHP statements are terminated by semicolon (;). The closing tag of a block of PHP code also automatically implies asemicolon (so you do not have to have a semicolon terminating the last line of a PHP block).

    Comments in PHPA comment in PHP code is a line that is not read/executed as part of the program. Its only purpose is to be read bysomeone who is editing the code!

    Comments are useful for:

    To let others understand what you are doing - Comments let other programmers understand what you were doing ineach step (if you work in a group)To remind yourself what you did - Most programmers have experienced coming back to their own work a year or twolater and having to re-figure out what they did. Comments can remind you of what you were thinking when youwrote the code

    PHP supports three ways of commenting:

    Example

    Run example

    Example

    Run example

    However; in PHP, all variables are case-sensitive.

    In the example below, only the first statement will display the value of the $color variable (this is because $color, $COLOR,and $coLOR are treated as three different variables):
