Cookies in PHP

 Cookies in PHP

Cookies are small text files that are stored on a user's computer. PHP provides built-in functions to set, retrieve, and delete cookies.

Example:

php

// set a cookie

$name = "John";

setcookie("name", $name, time() + (86400 * 30), "/"); // expires in 30 days

// retrieve a cookie

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

    echo "Hello " . $_COOKIE["name"];

}

// delete a cookie

setcookie("name", "", time() - 3600, "/");
