btw: we can loop over the results - with a iteration -

 

especially i wanna know: how to do the String concatenation with PHP ; note i wanna do it with curl!

function get_page_data($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
if($output!=false && $_POST['dt']=='No')
   return $output;
curl_close($ch);
}

for($i=1;$i<=$match[1];$i++)
{
$url = "http://www.example.com/page?page={$i}";
$data = get_page_data($url);
if($data) {
   $cleaned = string_between('onload="check();">', '</body>', $data);
   return = stip_tags($cleaned, '<table><tr><td><div>');
}
}

 

any and all help will be  greatly appreciated
