php自动提交表单的方法(基于fsockopen与curl)


            本文实例讲述了php基于fsockopen与curl实现自动提交表单的方法。分享给大家供大家参考，具体如下：

fsockopen和curl都可以做php自动提交表单

1. fsockopen方法:

php代码:





<?php

/*-----------------------------------------------------------

*功能：使用PHP socke 向指定页面提交数据

*作者：果冻  说明：post($url, $data)

*

*    $url   = 'http://www.xxx.com:8080/login.php';

*    $data[user] = 'hong';

*    $data[pass] = 'xowldo';

*    echo post($url, $data);

*-----------------------------------------------------------*/

function post($url, $data) {

  $url = parse_url($url);

   if (!$url) return "couldn't parse url";

   if (!isset($url['port'])) { $url['port'] = ""; }

   if (!isset($url['query'])) { $url['query'] = ""; }

  $encoded = "";

   while (list($k,$v) = each($data)) {

    $encoded .= ($encoded ? "&" : "");

    $encoded .= rawurlencode($k)."=".rawurlencode($v);

   }

  $fp = fsockopen($url['host'], $url['port'] ? $url['port'] : 80);

   if (!$fp) return "Failed to open socket to $url[host]";

  fputs($fp, sprintf("POST %s%s%s HTTP/1.0n", $url['path'], $url['query'] ? "?" : "", $url['query']));

  fputs($fp, "Host: $url[host]n");

  fputs($fp, "Content-type: application/x-www-form-urlencodedn");

  fputs($fp, "Content-length: " . strlen($encoded) . "n");

  fputs($fp, "Connection: closenn");

  fputs($fp, "$encodedn");

  $line = fgets($fp,1024);

   if (!eregi("^HTTP/1.. 200", $line)) return;

  $results = ""; $inheader = 1;

   while(!feof($fp)) {

    $line = fgets($fp,1024);

     if ($inheader && ($line == "n" || $line == "rn")) {

    $inheader = 0;

   }

   elseif (!$inheader) {

    $results .= $line;

   }

   }

  fclose($fp);

   return $results;

}

/*

$url = 'http://video.xxx.com:80/game_vm.php';

$data['gid'] = '1';

echo post($url, $data);

*/

?>







2. Curl方法：

php代码:





<?php

  $url = 'http://localhost/curl/result.php';

  $params = "param=123&param2=333"; //What will be posted

  $user_agent = "Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)";

  $ch = curl_init();

  curl_setopt($ch, CURLOPT_POST,1);

  curl_setopt($ch, CURLOPT_POSTFIELDS,$params);

  curl_setopt($ch, CURLOPT_URL,$url);

  curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);

  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

  $result=curl_exec ($ch); //execut

  curl_close ($ch);

  echo "Results: <br>".$result;

?>







result.php (just for test)





<?php

print_r($_POST);

?>
