Subject: Overriding Default Functions
From: acox@broadwick.com (Alan Cox)

Hello - 
  Is there a way to build an extension that overrides the default
behavior of a built-in PHP function?  Would it be possible to add an
extension that removes a PHP function, so that I could redefine it in my
PHP code?

  What I want to do is override the time calculations.  We are running
unit tests on a testing server that are dependent on time.  For
instance, there is one behavior before the 15th of the month and another
one on or after the 15th.  I'm not able to change the system time, since
this testing server is used by a lot of people.  What I'd like to be
able to do is load a module in the unit test that makes it so that a
custom time() function is used.  This time() function wouldn't look at
the system clock for the time.

Thanks for your help.
Alan
