Using Proxy On Script

I wrote a script.
I'm using file_get_contents function.
With this function i'm getting a domain adress and taking something from this page. But i'm getting rapidly. script always uses file_get_contents
For example google.com
for example if you make 900 or more searchs per a day google blocks you.
I have same problem with another site. So i want to use proxy with my script while using file_get_contents. maybe i can solve this issue. Think like your computer. It will change proxy in the script.

How can i do it ? With which function ?
Thank you

 

1. Get a proxy list.
2. Use CURL
3. Alternate the proxies with the CURL calls.

 

I tried it but it doesn't show me the content .Am i doing something wrong ?

<?
   $cUrl = curl_init();
   curl_setopt($cUrl, CURLOPT_URL, "http://www.google.com");
   curl_setopt($cUrl, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($cUrl, CURLOPT_TIMEOUT, 'timeout_in_seconds');
   curl_setopt($cUrl, CURLOPT_PROXY, '164.58.18.25:80');
   $pageContent = trim(curl_exec($cUrl));
   curl_close($cUrl);
   echo $pageContent;
   ?>

You need to set:

set_curlopt($cUrl, CURLOPT_HTTPPROXYTUNNEL, true);

 

I pust it but no change
and not set_curlopt - curl_setopt

<?
   $cUrl = curl_init();
   curl_setopt($cUrl, CURLOPT_HTTPPROXYTUNNEL, true);
   curl_setopt($cUrl, CURLOPT_URL, "http://www.google.com");
   curl_setopt($cUrl, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($cUrl, CURLOPT_TIMEOUT, 'timeout_in_seconds');
   curl_setopt($cUrl, CURLOPT_PROXY, '164.58.18.25:80');
   
   $pageContent = trim(curl_exec($cUrl));
   curl_close($cUrl);
   
  
   echo $pageContent;
   ?>

What makes you so sure that 164.58.18.25:80 is even a valid proxy? It doesn't work from here in Firefox...
