How to use proxies in PHP code?

  $proxy = '1.1.1.1:8800';  // <-- Replace 1.1.1.1:8800 with your proxy IP:PORT
$url = 'http://www.ipcheckit.com';
$content = getUrlContents($url, $proxy);
print $content;

function getUrlContents($url, $proxy = NULL, $post_data = NULL, $timeout = 30, $userpass = NULL) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
if ($post_data !== NULL) {
curl_setopt($curl, CURLOPT_POST, TRUE);
curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data);
}
if ($proxy != NULL) {
curl_setopt($curl, CURLOPT_PROXY, $proxy);
}
if ($userpass != NULL) {
curl_setopt($curl, CURLOPT_USERPWD, $userpass);
}
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);
curl_setopt($curl, CURLOPT_MAXREDIRS, 5);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, FALSE);
$contents = curl_exec($curl);
curl_close($curl);
return $contents;
}
