Couldn't it be solved with just a warning when a function is defined also in user level space and use the user-defined function instead of the one provided by php? Then old systems could work fine, and also the author could notice that a new function is added to php with the same name. I had the same problem before with array_search and was a real pain updating all the sites and sending patches to customers after they installed new version php. Just an idea... Arpi
