$result = curl_post$ry_url $data array $cookie;帮我封装一下这个方法

function curl_post($url, $data, $headers = array(), $cookie = "") { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); if (!empty($cookie)) { curl_setopt($ch, CURLOPT_COOKIE, $cookie); } $result = curl_exec($ch); curl_close($ch); return $result; }

$result = curl_post($ry_url, $data, array(), $cookie);
