I am currently using

preg_replace('/[^a-zA-Z0-9]+/', '_', $str)

what would be the alternative function using preg_replace_callback?

    Why do you want to do that? This would only call an unnecessary function call which you don't need here Commented Jul 16, 2015 at 9:02
  • What have you tried? You already have most parts (esp. the regex), a function that returns '_' shouldn't be too difficult to implement - or is it? Commented Jul 16, 2015 at 9:03
  • Yes, can you please do it for me? Commented Jul 16, 2015 at 10:02

I did it myself

function url_title($mystr){
	$result = '';
	$result .= preg_replace_callback(
                '/[^a-zA-Z0-9]+/',
                function ($matches) { return '_'; }, 
                $mystr);
						
	return strtolower($result);
}

$mystr = "some string here";
echo url_title($mystr);
