PHP, 'Haystack contains Needle?'

Question

Assuming this works properly for telling if a substring is in a string, is there a more concise way to do this?

if(is_int(strpos($haystack, $needle))){
   ...
}

Answer 1

I wouldn't do it that way. Just make a strict comparison to FALSE.

$found = strpos($haystack, $needle) !== FALSE;
