Re: switch, equality and preg_match

If you look back to the original problem, switch was matching the 0 returned from preg_match to a string. However, if the return value is a boolean it would not match 0 to a string. However, I guess it would then match the true to a string. Brian Moon ------------------------------------------ dealnews.com, Inc.
