using proxy server with php

[v_i_p]

hi everyone,
i am trying to hide my ip while executing my script, so i wrote this code to this purpose;

$requestUrl=$_POST['site'];
///ip hide
  $cUrl = curl_init();
  curl_setopt($cUrl, CURLOPT_URL, $requestUrl);
  curl_setopt($cUrl, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($cUrl, CURLOPT_TIMEOUT, '900');
  curl_setopt($cUrl, CURLOPT_PROXY, '200.65.127.163:80');
  $pageContent = trim(curl_exec($cUrl));
  curl_close($cUrl);
////////////////


But something is wrong with this code. when i tried it with different stat scripts, hit which is added by my code is  changing. In fact, i want to add unique hits to script. can u help me please or tell me a way to hide my ip???
