## #1736 — Sterling Hughes — 2003-05-19T17:00:50+00:00

Hi,

Attached is a patch which adds a new function
fast_call_user_function().  fast_call_user_function allows you to cache
the lookups of function calls, this way when you call the same function
repeatedly (as in `usort()` or any callback code), it doesn't need to be
looked up over and over and over and over and over again.

I've ported `usort()` and friends over to using fast_call_user_function()
and it resulted in around a 15% speedup.  If no one objects I'm going to
commit this to Zend, and then make the necessary changes in the code (at
least in ext/standard).
