For a simple alpha-numeric check you can use:

PHP Code:


			
if(preg_match('/[^a-z0-9\s]/i', $szInput))//can also be '/[^a-z\d\s]/i'
{
    die('illegal chars found');
}

That script should also ignore white space and is case insensitive, just remove '\s' and the 'i' at the end if you want to remove these features ('\s' being White space and 'I' being case sensitivity)
