Simple cURL example

function DownloadUrl($Url){
 
    // is curl installed?
    if (!function_exists('curl_init')){ 
        die('CURL is not installed!');
    }
 
    // create a new curl resource
    $ch = curl_init();
 
    /*
    Here you find more options for curl:
    http://www.php.net/curl_setopt
    */
 
    // set URL to download
    curl_setopt($ch, CURLOPT_URL, $Url);
 
    // set referer:
    curl_setopt($ch, CURLOPT_REFERER, "http://www.google.com/");
 
    // user agent:
    curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
 
    // remove header? 0 = yes, 1 = no
    curl_setopt($ch, CURLOPT_HEADER, 0);
 
    // should curl return or print the data? true = return, false = print
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 
    // timeout in seconds
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
 
    // download the given URL, and return output
    $output = curl_exec($ch);
 
    // close the curl resource, and free system resources
    curl_close($ch);
 
    // print output
    return $output;
