DEMO of Setting PHP data array as cookies by using a form input text box

Create related cookie values

Bracket notation creates related values that PHP can read as a nested cookie array on the next request.

<?php
$options = [
    'expires' => time() + 3600,
    'path' => '/',
    'secure' => true,
    'httponly' => true,
    'samesite' => 'Lax',
];

setcookie('Plus2netCookie[name]', 'Alex', $options);
setcookie('Plus2netCookie[city]', 'Hyderabad', $options);
?>

Cookie note: Secure cookies require HTTPS. Choose SameSite and HttpOnly settings according to how the cookie is actually used.

Current example first; the detailed tutorial examples below are retained for additional learning and comparison.
