unregister functions

[Anon]

Is there a way to unregister a function from the user-functions-array? Why would anyone need this.

Well, I get function-redeclared-errors all over the place because I am basically executing the code from the same file a second time... since functions seem to be declared BEFORE the actual parsing process they collide with my engine which first parses the code (to translate custom-tags, templates and stuff like that) and then executes it... of course then all functions will be declared twice...

Is there a way to either hinder PHP from registring function up to a certain point or unregister function at runtime?

Well the bad news is that

"PHP does not support function overloading, nor is it possible to undefine or redefine previously-declared functions."

The good news (a workaround) won't probably won't come from me; I'm just having trouble picturing your situation. Would it be possible to treat the first load of functions as a big text string (to prevent PHP from executing it), process it there and then eval() it to declare them? Would it perhaps be a matter of replacing an include() with an include_once()?
