This article describes the method of automatically submitting forms in PHP based on fsockopen and curl. Share it with everyone for your reference, the details are as follows:

Both fsockopen and curl can do PHP automatic form submission

1. fsockopen method:

php code:

<&#63;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 &#63; "&" : "");
    $encoded .= rawurlencode($k)."=".rawurlencode($v);
   }
  $fp = fsockopen($url['host'], $url['port'] &#63; $url['port'] : 80);
   if (!$fp) return "Failed to open socket to $url[host]";
  fputs($fp, sprintf("POST %s%s%s HTTP/1.0n", $url['path'], $url['query'] &#63; "&#63;" : "", $url['query']));
  fputs($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);
*/
&#63;>

2. Curl method:

php code:

<&#63;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;
&#63;>

result.php (just for test)

<&#63;php
print_r($_POST);
&#63;>
