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);
    ?>
