Session

PHP sessions are a way to store and retrieve data for a particular user across multiple page requests. When a user visits a website, a unique session ID is assigned to them, and this session ID is stored as a cookie on their browser or passed through the URL.

The session ID allows the server to associate the user’s subsequent requests with their specific session data. This session data is stored on the server, typically in files or a database, and is accessible throughout the user’s browsing session.

Sessions are commonly used to store user-specific information, such as login credentials, shopping cart items, or preferences. The session data can be accessed and modified using the $_SESSION superglobal array in PHP.

Here’s a basic example of how to use PHP sessions:

  1. Start a session using the session_start() function at the beginning of your PHP script.
session_start();
  1. Store data in the session by assigning values to $_SESSION array keys.
$_SESSION['username'] = 'osmankayi';
$_SESSION['cart'] = ['item1', 'item2', 'item3'];
  1. Retrieve session data on subsequent pages by accessing the $_SESSION array.
echo $_SESSION['username'];  // Output: osmankayi
print_r($_SESSION['cart']);  // Output: Array ( [0] => item1 [1] => item2 [2] => item3 )
  1. Destroy the session and clear session data using session_destroy() when the user logs out or the session is no longer needed.
session_destroy();

Sessions provide a way to maintain stateful behavior in PHP applications, allowing you to keep track of user-specific information throughout their interaction with your website.
