Re: php模拟post提交数据,可用来网站的采集,登陆等等
// PHP POST数据的三种方法
// php有三种方法可以post数据,分别为Curl、socket、file_get_contents:
/**
* Socket版本
* 使用方法：
* $post_string = "app=socket&version=beta";
* request_by_socket('facebook.cn','/restServer.php',$post_string);
*/
function request_by_socket($remote_server, $remote_path, $post_string, $port = 80, $timeout = 30)
{
$socket = fsockopen($remote_server, $port, $errno, $errstr, $timeout);
if (!$socket) die("$errstr($errno)");
fwrite($socket, "POST $remote_path HTTP/1.0\r\n");
fwrite($socket, "User-Agent: Socket Example\r\n");
fwrite($socket, "HOST: $remote_server\r\n");
fwrite($socket, "Content-type: application/x-www-form-urlencoded\r\n");
fwrite($socket, "Content-length: " . (strlen($post_string) + 8) . '\r\n');
fwrite($socket, "Accept:*/*\r\n");
fwrite($socket, "\r\n");
fwrite($socket, "mypost=$post_string\r\n");
fwrite($socket, "\r\n");
$header = "";
while ($str = trim(fgets($socket, 4096))) {
$header .= $str;
}
$data = "";
while (!feof($socket)) {
$data .= fgets($socket, 4096);
}
return $data;
}
/**

* 使用方法：
* $post_string = "app=request&version=beta";
* request_by_curl('http://facebook.cn/restServer.php',$post_string);
*/

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Jimmy's CURL Example beta");
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
/**
* 其它版本
* 使用方法：
* $post_string = "app=request&version=beta";
* request_by_other('http://facebook.cn/restServer.php',$post_string);
*/
