PHP Post data with Fsockopen

by

There are many small errors in your code. Here’s a snippet which is tested and works.

<?php

$fp = fsockopen('example.com', 80);

$vars = array(
    'hello' => 'world'
);
$content = http_build_query($vars);

fwrite($fp, "POST /reposter.php HTTP/1.1\r\n");
fwrite($fp, "Host: example.com\r\n");
fwrite($fp, "Content-Type: application/x-www-form-urlencoded\r\n");
fwrite($fp, "Content-Length: ".strlen($content)."\r\n");
fwrite($fp, "Connection: close\r\n");
fwrite($fp, "\r\n");

fwrite($fp, $content);

header('Content-type: text/plain');
while (!feof($fp)) {
    echo fgets($fp, 1024);
}

And then at example.com/reposter.php put this

<?php print_r($_POST);

When run you should get output something like

HTTP/1.1 200 OK
Date: Wed, 05 Jan 2011 21:24:07 GMT
Server: Apache
X-Powered-By: PHP/5.2.9
Vary: Host
Content-Type: text/html
Connection: close

1f
Array
(
    [hello] => world
)
