php模拟post提交数据,用处很多,可用来网站的采集,登陆等等
  1. //以程序登陆一个论坛登录为例
  2. function bbslogin($user_login, $password, $host, $port = "80") {
  3. //需要提交的post数据
  4. $argv = array('cookie' => array('user_login' => $user_login, 'password' => $password, '_wp_http_referer' => '/bbpress/', 're' => '', 'remember' => true));
  5. foreach ($argv['cookie'] as $key => $value) {
  6. $params[] = $key . '=' . $value;
  7. }
  8. $params = implode('&', $params);
  9. $header = "POST /bbpress/bb-login.php HTTP/1.1\r\n";
  10. $header .= "Host:$host:$port\r\n";
  11. $header .= "Content-Type: application/x-www-form-urlencoded\r\n";
  12. $header .= "Content-Length: " . strlen($params) . "\r\n";
  13. $header .= "Connection: Close\r\n\r\n";
  14. $header .= $params;
  15. $fp = fsockopen($host, $port);
  16. fputs($fp, $header);
  17. while (!feof($fp)) {
  18. $str = fgets($fp);
  19. //以下是自己的逻辑代码,这里主要是模拟cookie,可用来同步登陆
  20. if (!(strpos($str, "Set-Cookie:") === false)) {
  21. $tmparray = explode(" ", $str);
  22. $cookiearray = explode("=", $tmparray[1]);
  23. $cookiepaths = explode("=", $tmparray[6]);
  24. $cookiename = urldecode($cookiearray[0]);
  25. $cookievalue = urldecode(substr($cookiearray[1], 0, strlen($cookiearray[1]) - 1));
  26. $cookietime = time() + 3600 * 24 * 7;
  27. $cookiepath = urldecode(substr($cookiepaths[1], 0, strlen($cookiepaths[1]) - 1));
  28. setcookie($cookiename, $cookievalue, $cookietime, $cookiepath);
  29. }
  30. }
  31. fclose($fp);
  32. }
  33. ?>
  1. // PHP POST数据的三种方法
  2. // php有三种方法可以post数据,分别为Curl、socket、file_get_contents:
  3. /**
  4. * Socket版本
  5. * 使用方法:
  6. * $post_string = "app=socket&version=beta";

  12. if (!$socket) die("$errstr($errno)");
  13. fwrite($socket, "POST $remote_path HTTP/1.0\r\n");
  14. fwrite($socket, "User-Agent: Socket Example\r\n");
  15. fwrite($socket, "HOST: $remote_server\r\n");
