}

if(preg_match("/^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\z/",@$_GET['ip']) == true)
{
    dnsbllookup($_GET['ip']);
}
?>

and what this does it checks an IP if is listed on certain blacklists

http://127.0.0.1/check4_html.php?ip=123.123.123.123

Not listed on 123.123.123.123.access.redhawk.org!
Not listed on 123.123.123.123.b.barracudacentral.org!
Not listed on 123.123.123.123.bl.csma.biz!
Not listed on 123.123.123.123.bl.emailbasura.org!

bu i have a little problem, i want to flush the output every time a check has been made, how can i do this?

The first thing that happen when the script runs, i wait 20 secs and then 20 checks pops up, then 1 per second, why is that?

Any help would be appreciated.

    This Concept works for me :)

    ini_set('output_buffering','on');
    ini_set('zlib.output_compression', 0);
    ini_set('implicit_flush',1);
    ob_implicit_flush();
    
    echo ("<html><head><head><body>");
    for($i=0;$i<20;$i++) {
          echo $i;
          echo str_repeat(" ", 500);
          ob_flush();
          flush();
          sleep(1);
    }

    flush() doesn't appear to be part of "output buffering" (ob).. Use ob_flush(). Also there should be no need for ob_end() and ob_start() if you use the proper function. :)

    void ob_flush ( void )

    This function will send the contents of the output buffer (if any). If you want to further process the buffer's contents you have to call ob_get_contents() before ob_flush() as the buffer contents are discarded after ob_flush() is called.

    This function does not destroy the output buffer like ob_end_flush() does.
