[RESOLVED] How do I check any case of a string and find it?

[RonB]

How do I check any case of a string and find it?

Say, someone entered in...

"hey what's new MaN"

and if I was looking for the word man, I wouldn't find it. So is there some kind of function that will check any case of a string that I'm looking for? Thank you.

If PHP5, you can use stripos(). I'd probably use preg_match() or preg_match_all() (depending on what you're trying to do) with the "i" modifier on the regex so that it works in any environment:

if(preg_match('/man/i', $string))
{
  echo "found it";
}

If you want to match the word "man" but not "manners" or "woman", then use the "\b" word boundary assertion:

if(preg_match('/\bman\b/i', $string))
{
  echo "found it";
}

stristr() - Searches for a string within a string, case insensitive.

http://us3.php.net/manual/en/function.stristr.php

<?php
  $email = '[e-mail]';
  echo stristr($email, 'e');
// outputs [e-mail]
?> 

Hope This Helps!
