php使用curl存储cookie的示例

代码如下:
<?php
$curl = curl_init();
$url = '//www.gxlcms.com/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);
