PHP Sessions

 PHP Sessions

Sessions allow you to store data on the server that can be accessed across multiple pages. PHP provides built-in functions to start and manage sessions.

Example:

php

// start a session

session_start();

// store data in a session

$_SESSION["name"] = "John";

// retrieve data from a session

if (isset($_SESSION["name"])) {

    echo "Hello " . $_SESSION["name"];

}

// destroy a session

session_destroy();
