PHP convert a txt string all to lowercase question

newbie alert :)

[Duke_of_Url]

I did a quick site search but didn't pull back anything to do with this (apologies if I missed it)!

I'm tinkering with php for the first time and I need to know if theres a built-in function out there I can use to take a text string (mix of upper and lowercase chars), and convert it so thats its all in lowercase.

Can anyone advise? I had a look on php.net but didnt see anything obvious :)

thanks

Hi DoU, strtolower.

Oh well, looks like I'm too slow!
