thanks for everyone's help...

> How do you mean its part of your code library?

I mean that the function I'm having to call is passed an array (coming from
a databse) and it has an option to do an ereg_replace() on the incoming
array. Due to the amount of other code relying on it, is very hard to change
without causing something strange to happen elsewhere :(

If all the code was mine, then I wouldn't have any reservations on changing
it in an instant. I'm having to improve the code gradually (good luck to me)
