PHP Post data with Fsockopen
fsockopen, php, sockets
Solution
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

Problem
I am attempting to post data using fsockopen, and then returning the result. Here is my current code: ``` <?php $data="stuff=hoorah\r\n"; $data=urlencode($data); $fp = fsockopen("www.website.com", 80, $errno, $errstr, 30); if (!$fp) { echo "$errstr ($errno)<br />\n"; } else { $out = "POST /script.php HTTP/1.0\r\n"; $out .= "Host: www.webste.com\r\n"; $out .= 'Content-Type: application/x-www-form-urlencoded\r\n'; $out .= 'Content-Length: ' . strlen($data) . '\r\n\r\n'; $out .= "Connection: Close\r\n\r\n"; fwrite($fp, $out); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp); } ?> ``` It is supposed to echo the page, and it is echoing the page, but here is the script for script.php ``` <?php echo "<br><br>"; $raw_data = $GLOBALS['HTTP_RAW_POST_DATA']; parse_str( $raw_data, $_POST ); //test 1 var_dump($raw_data); echo "<br><br>": //test 2 print_r( $_POST ); ?> ``` The outcome is: HTTP/1.1 200 OK Date: Tue, 02 Mar 2010 22:40:46 GMT Server: Apache/2.2.3 (CentOS) X-Powered-By: PHP/5.2.6 Content-Length: 31 Connection: close Content-Type: text/html; charset=UTF-8 string(0) "" Array ( ) What do I have wrong? Why isn't the variable posting its data?
