Replacing everything but letters, numbers and hyphens

Hey there,

I asked a little while back how to replace everything but numbers and letters in a string? Well, I ended up with this code:

PHP Code:


		
			
$string = preg_replace('/ї^\wa-z0-9]/i', '', $string);

The only problem is that it removes hyphens (which is what I want) and doesn't remvoe underscorese (which is what I don't want)

Is there anyway I can make the above code not remove hyphens from a string of text?

This should do the trick:

PHP Code:


		
			
<?php

 $string = preg_replace('/[^\-\w]/i', '',  $string);

?>

Hope that helps!
