Question

I currently run a PHP-script using CURL to send data to another server, to do run a PHP-script that could take up to a minute to run.
This server doesn’t give any data back. But the CURL-request still has to wait for it to complete, and then it loads the rest of the orignal page. I would like my PHP-script to just send the data to the other server and then not wait for an answer.

So my question is how should I solve this? I have read that CURL always has to wait. What are your suggestions?

This might be a useful starting point, flagrantly copypasted from here

function curl_post_async($url, $params)
{
    $post_string = http_build_query($params);

    $parts=parse_url($url);

    $fp = fsockopen($parts['host'], 
        isset($parts['port'])?$parts['port']:80, 
        $errno, $errstr, 30);

    //pete_assert(($fp!=0), "Couldn't open a socket to ".$url." (".$errstr.")");(optional)

    $out = "POST ".$parts['path']." HTTP/1.1\r\n";
    $out.= "Host: ".$parts['host']."\r\n";
    $out.= "Content-Type: application/x-www-form-urlencoded\r\n";
    $out.= "Content-Length: ".strlen($post_string)."\r\n";
    $out.= "Connection: Close\r\n\r\n";
    if (isset($post_string)) $out.= $post_string;

    fwrite($fp, $out);
    fclose($fp);
}
