## #11792 — Nathan — 2004-08-01T18:35:49+00:00

Dear List,

i was using the get_defined_constants function the first time today and sadly for me i read in the man-pages that it displays _all_ defined constants. 

Wouldn't it make sense to implement a function like get_user_defined_constants which would only display those constants `define()`ed by the user during the development time? If it's not worth a function maybe an parameter would be nice, like 

// return an array of constants defined by the user using `define()`;
get_defined_constants(C_USER) 

// return an array with all defined constants 
get_defined_constants(C_ALL) 


This would also apply to the functions get_defined_functions and get_defined_vars. Maybe there is already a way to figure such things out, but i haven't found anything in the man-pages. 

I would be glad to know if something alike exists, or if not, why it wouldn't make sense.

Thanks in advance,
Nathan


PS: Please CC me, as i'm not on the list

it's a nice idea, and personally, i would prefer a simple boolean parameter
instead of constants where there's only 2 possibilities anyway..

The latter is much more readable, though.

Cheers,

The bool method is used in numerous other places, and consistancy is good.
