Using fsockopen to POST to a GET query URL

Question

Whats wrong with this raw HTTP call using fsockopen?

POST /api/?action=report HTTP/1.1
Host: www.webhosting-performance.com
Content-Type: application/x-www-form-urlencoded
Conent-Length: 9
Connection: close

test=test

The remote script says var_dump($_POST) is empty.

A snippet of my php code looks like this:

if (ini_get('allow_url_fopen') > 0) {

  $parts = parse_url($url);
  $fp = fsockopen($parts['host'], isset($parts['port']) ? $parts['port'] : 80, $errno, $errstr, 30);

  if (!$fp) throw new Exception("Problem with $url, $errstr");

  $post_string = $post_fields ? http_build_query($post_fields) : '';

  $out = ($post_string ? "POST " : "GET ") . $parts['path'] . ((isset($parts['query'])) ? "?" . $parts['query'] : false) ." HTTP/1.1\r\n"
       . "Host: ". $parts['host'] ."\r\n"
       . ($post_string ? "Content-Type: application/x-www-form-urlencoded\r\n" : false)
       . "Conent-Length: ". strlen($post_string) ."\r\n"
       . "Connection: close\r\n"
       . "\r\n" . $post_string;

  fwrite($fp, $out);

  // ...

} else {
  // use curl
}

Answer 1

You basically just have a typo:

Conent-Length: 9

See the missing t in Content-Length:

The real question is (not to malign your efforts at constructing something yourself), why aren't you using cURL or PEARs HTTP Request class?
