在Curl中我们有些时候需要将cookies字符串转换为数组，可以用下面的方法

public function setCookieString($string)
{
    $result = array();
    if(preg_match_all('/\s*([^;=]+)=([^;]+)/i',$string,$matches) > 0){
        if(isset($matches[1]) && isset($matches[2])){
            if(count($matches[1]) == count($matches[2])){
                foreach ($matches[1] as $handle => $key) {
                    $result[$key] = $matches[2][$handle];
                }
            }
        }
    }
    return $result;
}

参数只能放cookies字符串，如下图绿色框的部分
