Some PHP4 code I have to work on includes several global variables, that are constantly being referenced everywhere. I've somewhat avoided it, in that I'll wrap a particular global with a get() method, and in all the remaining functions just use what that get() returns, rather than referencing the global variable directly anywhere else but inside the get() method. So, if there are gotchas out there in referencing a global variable like global $MyGlobal; without using the $GLOBALS array, I need to understand. -- CRB Let me introduce you to my very own DMCA-protected encryption key: BC 1B 64 4A 8D DE 49 E8 C3 7D CC EE 1A AD EE F5 (compliments of Freedom-to-Tinker http://www.freedom-to-tinker.com/?p=1155)
