Last update on December 20 2024 10:27:04 (UTC/GMT +8 hours)

Write a PHP script to delete a cookie named "username".

Sample Solution:

PHP Code :

<?php
$cookieName = "username";

// Set the cookie expiration time to the past to delete the cookie
setcookie($cookieName, "", time() - 3600);

echo "Cookie named 'username' has been deleted.";
?>

Sample Output:

Cookie named 'username' has been deleted.

Explanation:

In the above exercise -

The variable $cookieName contains the cookie name we want to delete, "username".
To delete the cookie, we use the setcookie() function with the same cookie name, an empty value, and a past expiration time (specifically, one hour ago). Setting the expiration time to the past causes the cookie to be immediately expired and removed from the browser.
After deleting the cookie, we display a message indicating that the cookie named "username" has been deleted.
