PHP simulates post submission data

PHP simulates post submission data, which has many uses. It can be used for website collection, login, etc.

//Take the program to log in to a forum as an example
function bbslogin($user_login, $password, $host, $port = "80") {
 //Post data that needs to be submitted
 $argv = array('cookie' => array('user_login' => $user_login, 'password' => $password, '_wp_http_referer' => '/bbpress/', 're' => ' ', 'remember' => true));
 foreach ($argv['cookie'] as $key => $value) {
 $params[] = $key . '=' . $value;
 }
 $params = implode('&', $params);
 $header = "POST /bbpress/bb-login.php HTTP/1.1rn";
 $header .= "Host:$host:$portrn";
 $header .= "Content-Type: application/x-www-form-urlencodedrn";
 $header .= "Content-Length: " . strlen($params) . "rn";
 $header .= "Connection: Closernrn";
 $header .= $params;
 $fp = fsockopen($host, $port);
 fputs($fp, $header);
 while (!feof($fp)) {
 $str = fgets ($fp);
 //The following is my own logic code, which mainly simulates cookies and can be used to log in synchronously
 if (!(strpos($str, "Set-Cookie:") === false)) {
 $tmparray = explode(" ", $str);
 $cookiearray = explode("=", $tmparray[1]);
 $cookiepaths = explode("=", $tmparray[6]);
 $cookiename = urldecode($cookiearray[0]);
 $cookievalue = urldecode(substr($cookiearray[1], 0, strlen($cookiearray[1]) - 1));
 $cookietime = time() + 3600 * 24 * 7;
 $cookiepath = urldecode(substr($cookiepaths[1], 0, strlen($cookiepaths[1]) - 1));
 setcookie($cookiename, $cookievalue, $cookietime, $cookiepath);
 }
 }
 fclose($fp);
}
?>

//Three methods of PHP POST data
//PHP has three methods to post data, namely Curl, socket, file_get_contents:


/**

 * Usage:
 * $post_string = "app=socket&version=beta";
 * request_by_socket('facebook.cn','/restServer.php',$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 $remote_path HTTP/1.0rn");
 fwrite($socket, "User-Agent: Socket Examplern");
 fwrite ($socket, "HOST: $remote_serverrn");
 fwrite($socket, "Content-type: application/x-www-form-urlencodedrn");
 fwrite($socket, "Content-length: " . (strlen ($post_string) + 8) . 'rn');
 fwrite($socket, "Accept:*/*rn");
 fwrite($socket, "rn");
 fwrite($socket, "mypost=$ post_stringrn");
 fwrite($socket, "rn");
 $header = "";
 while ($str = trim(fgets($socket, 4096))) {
 $header .= $str;
 }
 $data = "";
 while (!feof($socket)) {
 $data .= fgets($socket, 4096);
 }
 return $data;
}
