This document discusses PHP web programming basics including includes, GET, POST, and sessions. It explains that includes allow inserting one PHP file into another, GET passes URL parameters in an array, POST passes form data in an array, and sessions store user information across multiple pages using session variables. The document provides code examples and compares GET and POST, noting that POST is more secure but both require security efforts.

Get
• What is GET ?
An associative array of variables passed to the current script via the
URL parameters.
• Example:
 www.mysite.com/index.php?p=home&s=1
• How can i catch the data ?
$page = $_GET[‘p’] ;
$start = $_GET[‘s’];
• When to use ?
when Information that sent is visible to everyone.
• What about security ?
Not Safe ! Need some efforts ..

POST
• What is POST?
An associative array of variables passed to the current script via the
HTTP POST method.
• Example:
using form tag.
• How can i catch the data ?
$name = $_POST[‘name’];
$pass = $_POST[‘pass’];
• When to use ?
when Information that sent is invisible to others.
• What about security ?
Not Safe ! But better than GET Need some efforts ..

GET vs POST
• Both GET and POST create an array
This array holds key/value pairs, where keys are the names of the form
controls and values are the input data from the user.
• Both GET and POST are treated as $_GET and $_POST.
These are “superglobals”, which means that they are always accessible,
regardless of scope - and you can access them from any function, class
or file without having to do anything special.
• $_GET is an array of variables passed to the current script via the URL
parameters.
• $_POST is an array of variables passed to the current script via the
HTTP POST method.

Session
• A PHP Session variable is used to store information about the user, or
change settings for a user session.
• Session variables hold information about one single user, and are
available to all pages in one application.
• session_start() Start new or resume existing session.
• session_destroy() Reset your session and you will lose all your stored
session data.
• Example :
$_SESSION['views']=1;
