使用php自动提交表单的方法

介绍了PHP自动提交表单的.方法,结合实例形式分析了php基于fsockopen与curl两种实现技巧,需要的朋友可以参考下。

fsockopen和curl都可以做php自动提交表单

　　1. fsockopen方法:

<?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 = '';

* $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)."="rlencode($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 = '_';

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

echo post($url, $data);

*/

?>

$params = "param=123?m2=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;

?>
