使用PHP将数据cookie从另一个页面获取到另一个页面

i have two sites http://domain1/getcookieshere.php && http://domain2/reqcookie/reqcookieshere.php.

I've echoed $_COOKIE['cookie_name'] on getcookieshere.php. then on the reqcookieshere.php I've used $cookies = file_get_contents('http://ip/domain1/getcookieshere.php');

then I echo the $cookie, but it does not return or display on reqcookieshere.php.

any possible solution? thank you!

You can't get cookie from another domain. I guess what you need is CURL

<?php
$ch = curl_init('http://www.google.com/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$result = curl_exec($ch);
preg_match_all('/^Set-Cookie:\s*([^;]*)/mi', $result, $matches);
$cookies = array();
foreach($matches[1] as $item) {
    parse_str($item, $cookie);
    $cookies = array_merge($cookies, $cookie);
}
var_dump($cookies);
