php字符串取字串怎么做好；

[wh176781788]

如题，初学php，我现在想把 Set-Cookie: token=Z7JkalM7XNRH9skISadIuA00; Path=/
的token 和path的值取出来，该如何写好呢？如果以后可能有一个domain属性，能否也能取出呢。谢谢高人帮忙写一个。

$sTmp = 'Set-Cookie: token=Z7JkalM7XNRH9skISadIuA00; Path=/';
$s='/Set-Cookie:\s*token=(\w+);/i'
preg_match($s, $sTmp, $arr); 
echo $arr[1];

$sTmp = 'Set-Cookie: token=Z7JkalM7XNRH9skISadIuA00; Path=/';
$s='/Set-Cookie:.*path=([\/\.\w]+);/i'
preg_match($s, $sTmp, $arr); 
echo $arr[1];

$_COOKIE['token'];
$_COOKIE['Path'];
$_COOKIE['domain'];

$str = 'Set-Cookie: token=Z7JkalM7XNRH9skISadIuA00; Path=abackdead';
$strArr = explode(':', $str);
$valArr = explode(';',$strArr[1]);
$returnArr = array();
foreach($valArr as $key => $value){
$kv = explode('=',$value);
$returnArr[trim($kv[0])] = $kv[1];
}
要获取某个 key 的值的话只要:
比如是获取 domain
$returnArr['domain'];就可以了
