php使用curl存储cookie的示例

<?php
$curl = curl_init();
$url = http://www.jb51.net/admin/gateway/login;
$data = array(
 username=>admin,
 password=>123
);
$cookie = tempnam(./temp,cookie);
curl_setopt($curl,CURLOPT_URL,$url);
curl_setopt($curl,CURLOPT_POST,count($data));
curl_setopt($curl,CURLOPT_POSTFIELDS,$data);
curl_setopt($curl,CURLOPT_COOKIEJAR,$cookie);
ob_start();
curl_exec($curl);
$result = ob_get_contents();
ob_end_clean();
curl_close($curl);
