PHP internet cookies deleting from the client: demo

Delete each array-style cookie key

Expire each child cookie with the same scope used when it was created.

<?php
foreach (['name', 'city', 'state', 'zip'] as $key) {
    setcookie("Plus2netCookie[$key]", '', [
        'expires' => time() - 3600,
        'path' => '/',
        'secure' => true,
        'httponly' => true,
        'samesite' => 'Lax',
    ]);
}
?>

Cookie settings: Use Secure on HTTPS sites, HttpOnly when JavaScript does not need the cookie, and choose SameSite according to the cross-site behavior your application requires.

Cookie is removed. You can check this by going to Reading Cookies page to check.

setcookie('Plus2netCookie', '', ['expires' => time() - 3600, 'path' => '/', 'secure' => true, 'httponly' => true, 'samesite' => 'Lax']);
setcookie('Plus2netCookie[zip]', '', ['expires' => time() - 3600, 'path' => '/', 'secure' => true, 'httponly' => true, 'samesite' => 'Lax']);
setcookie('Plus2netCookie[city]', '', ['expires' => time() - 3600, 'path' => '/', 'secure' => true, 'httponly' => true, 'samesite' => 'Lax']);
setcookie('Plus2netCookie[state]', '', ['expires' => time() - 3600, 'path' => '/', 'secure' => true, 'httponly' => true, 'samesite' => 'Lax']);
setcookie('Plus2netCookie[name]', '', ['expires' => time() - 3600, 'path' => '/', 'secure' => true, 'httponly' => true, 'samesite' => 'Lax']);

Here time() gives us the time elapsed in seconds between current time and Unix Epoch (January 1 1970 00:00:00 GMT). From this value we are subtracting 3600 seconds to give a past time as expire time for the cookie.
