I know the page you mean, and I can't find it either :-( If you have { or } embedded in a string as regular output to the user, that will need to be escaped now. The other functions were all real "weird" ones that I never used, so didn't worry about :-^ What you might want to consider doing is installing *both* PHP3 and PHP4 at one time, and leaving pages as PHP3 until you can verify what does or doesn't work in some testing. There really were very, very, very few changes from PHP3 to PHP4, considering it was a complete re-write of the engine. Your upgrade will almost certainly be surprisingly uneventful :-) -- Visit the Zend Store at http://www.zend.com/store/ Wanna help me out? Like Music?
