Last update on December 20 2024 10:20:56 (UTC/GMT +8 hours)

Write a PHP script to retrieve and display the value of the cookie named "username".

Sample Solution:

PHP Code :

<?php
$cookieName = "username";

if (isset($_COOKIE[$cookieName])) {
    $cookieValue = $_COOKIE[$cookieName];
    echo "Value of cookie 'username': " . $cookieValue;
} else {
    echo "Cookie 'username' not found.";
}
?>

Sample Output:

Value of cookie 'username': Gulnara Serik.

Explanation:

In the above exercise -

First we define the variable $cookieName with the name of the cookie we want to retrieve, which is "username".
Next, we use the isset() function to check if the cookie with the specified name exists in the $_COOKIE superglobal array. If it exists, we retrieve its value using $_COOKIE[$cookieName] and store it in the variable $cookieValue.
We then display the cookie value by echoing the message "Value of cookie 'username': " concatenated with $cookieValue.
If the cookie does not exist, we display the message "Cookie 'username' not found."
