如何用 PHP 在 aaa.com 设置 bbb.com 的 cookie 呢？:doge:

[lxjsmdc]

<?php
setcookie("name1","value1",time()+3600*24,"/",'v2ex.com');
setcookie("name2","value2",time()+3600*24,"/",'.v2ex.com');
setcookie("name3","value3",time()+3600*24,"/",'www.v2ex.com');

setcookie("name4","value4",time()+3600*24,"/",'v2ex.com',true);
setcookie("name5","value5",time()+3600*24,"/",'.v2ex.com',true);
setcookie("name6","value6",time()+3600*24,"/",'www.v2ex.com',true);
?>

<a href="http://www.v2ex.com/">http://www.v2ex.com/</a>

除了用 js 和 iframe ，单单用 php 能否设置任意第三方网站的 cookie 呢？
