php cookie不刷新及时生效的实现代码

<?php
/**
 * 不刷新 cookie及时生效
 */
cookie("mycookie","cookievalue",time()+60);
cookie("mydemo",array('name'=>"demovalue_1",'address'=>"demovalue_2"),time()+60);
var_dump($_COOKIE["mycookie"]);
var_dump($_COOKIE["mydemo"]);    

//PHP COOKIE设置函数立即生效，支持数组
function cookie($var, $value='', $time=0, $path='', $domain='')
{
    $_COOKIE[$var] = $value;
    if(is_array($value)){
       foreach($value as $k=>$v){
          setcookie($var.'['.$k.']', $v, $time, $path, $domain, 0);
        }
    }else{
        setcookie($var, $value, $time, $path, $domain, 0);
     }
}
?>
