把curl回来的cookies处理成数组

把curl返回的cookies处理成数组
目的只是将Curl返回的Header里面的Cookies转化成数组和获取Location

例子：
……
Cache-Control: private,no-cache="set-cookie"
Expires: -1
Pragma: no-cache
Location: http://example.com/
Set-Cookie: B=1; Path=/
Set-Cookie: C=5; Path=/
Set-Cookie: R=5; Path=/
转成
array("B" => "1","C" => "5","R" => "5" )
并取出 Location 为 $l="http://example.com/";

谢谢了
------解决方案--------------------

$s = <<< TXT

Cache-Control: private,no-cache="set-cookie"

Expires: -1

Pragma: no-cache

Location: http://example.com/

Set-Cookie: B=1; Path=/

Set-Cookie: C=5; Path=/

Set-Cookie: R=5; Path=/

TXT;



$res = array();

foreach(preg_split("/[\r\n]+/", $s, -1, PREG_SPLIT_NO_EMPTY) as $row) {

  switch($k = strtok($row, ':')) {

    case 'Location':

      $res[$k][] = trim(strtok(''));

      break;

    case 'Set-Cookie':

      $res[$k][trim(strtok('='))] = trim(strtok(';'));

      break;

  }

}

print_r($res);

Array
(
[Location] => Array
(
[0] => http://example.com/
)

[Set-Cookie] => Array
(
[B] => 1
[C] => 5
[R] => 5
)

)
