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);
?>
