My issue with defining a user level function is:

a. the actual variable in question could not be passed
b. it incurs the overhead of calling a user-level function

I do admit that this may be a plausible solution for the majority of my 
examples in initializing the incoming script variables, but does not 
address the general problem of developing with E_NOTICE turned on - for 
instance, accessing globals or deep arrays that may or may not exist.

It is one of the great features of PHP - accessing an undefined variable, 
but one that is completely removed when E_NOTICE is turned on.


What is the overhead of calling a simple UDF in php?
