echo "<pre>";
echo PHP_EOL . $_GET["url"];
echo PHP_EOL . htmlentities($htm);
echo PHP_EOL;


// A FUNCTION TO RUN A CURL-GET CLIENT CALL TO A FOREIGN SERVER
function my_curl
( $url
, $timeout=3
, $error_report=TRUE
)
{
    $curl = curl_init();

    // HEADERS AND OPTIONS APPEAR TO BE A FIREFOX BROWSER REFERRED BY GOOGLE
    $header[] = "Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";

    // SET THE CURL OPTIONS - SEE http://php.net/manual/en/function.curl-setopt.php
    curl_setopt( $curl, CURLOPT_URL,            $url  );
    curl_setopt( $curl, CURLOPT_USERAGENT,      'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6'  );

    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, TRUE  );
    curl_setopt( $curl, CURLOPT_TIMEOUT,        $timeout  );

    // RUN THE CURL REQUEST AND GET THE RESULTS
    $htm = curl_exec($curl);

    // ON FAILURE HANDLE ERROR MESSAGE
    if ($htm === FALSE)
    {
        if ($error_report)
        {
            $err = curl_errno($curl);
            $inf = curl_getinfo($curl);
            echo "CURL FAIL: $url TIMEOUT=$timeout, CURL_ERRNO=$err";
            var_dump($inf);
        }
        curl_close($curl);
