php 模拟POST提交的2种方法详解

　　$post_data = array();

　　$post_data['clientname'] = "test08";

　　$post_data['clientpasswd'] = "test08";

　　$post_data['submit'] = "submit";

　　$url='http://xxx.xxx.xxx.xx/xx/xxx/top.php';

　　$o="";

　　foreach ($post_data as $k=>$v)

　　{

　　$o.= "$k=".urlencode($v)."&";

　　}

　　$post_data=substr($o,0,-1);

　　$ch = curl_init();

　　curl_setopt($ch, CURLOPT_POST, 1);

　　curl_setopt($ch, CURLOPT_HEADER, 0);

　　curl_setopt($ch, CURLOPT_URL,$url);

　　//为了支持cookie

　　curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');

　　curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

　　$result = curl_exec($ch);

　　$URL=‘http://xxx.xxx.xxx.xx/xx/xxx/top.php';

　　$post_data['clientname'] = "test08";

　　$post_data['clientpasswd'] = "test08";

　　$post_data['submit'] = "ログイン";

　　$referrer="";

　　// parsing the given URL

　　$URL_Info=parse_url($URL);

　　// Building referrer
