[PHP-DEV] call_user_method_array

[Wez Furlong]

Hi,

I have written a call_user_method_array function that,
surprise surprise, calls a user method and passes arguments from an array - the 
object/class equivalent of call_user_func_array.

The code is below.  In the function table, I have made the second arg passed by 
reference, as it is not very useful otherwise (a shortcoming of call_user_method).

I have CVS access and will add this code to basic_functions.c sometime tonight (in a 
couple of hours), unless anyone objects!
