让 PHP COOKIE 立即生效（不用刷新就可以使用） 

<?php
    function set_my_cookie($var, $value = '', $time = 0, $path = '', $domain = '') {
        $_COOKIE[$var] = $value;
        setcookie($var, $value, $time, $path, $domain);
    }
    // set_my_cookie('test', 'ryan_test');
    // echo $_COOKIE['test'];
    if ($_SERVER['REQUEST_METHOD'] == 'POST') {
        set_my_cookie('test1', 'ryan_test1');
    }
    echo $_COOKIE['test1'];
?>
