thanks for the help

@crypto-maniac I think you should try to google a little bit before asking for help (cause you would have figured it out if you tried), but here's some code to get you started:

$document = file_get_contents('urls.txt');
$hosts = explode(PHP_EOL, $document);
$ports = [21, 25, 80, 81, 110, 143, 443, 587, 2525, 3306];

foreach($hosts as $host){
	//just copy pasta from line 8 to 22
}
