Mark, thanks for your reply. The situation is, is that I am writing a
large piece of software with several hundred functions. At the beginning
of each function I have som initialization code that allows me to do
several thing.
Parse through the variables in a non standard way, and define a few
variables to be global within the function.
The only way I was able to accomplish this in the past was to call an
include from the beginning of each function (as there is no way to write a
function that uses func_get_args()). Calling this include however is quite
inneficient, and I have replaced most of what it does with my C extension.
I have also tried using the zend_register_auto_global function, but this
appears to cause a great deal of unpredictable behaviour.
Cheers,
Ken
