 New Comment:

Why are you passing an empty string in place of a number there?  You 
are essentially asking for an empty string to be printed with 0 decimal

places and you are getting back an empty string.  You also get a big 
warning about that, of course.  How about "a",0 what do you expect that

to return?  

I think the right solution for you here is to be explicit about casting

your weird inputs to a float.  number_format((float)$weird,'0') will 
take care of it.

Description:
------------
php -r 2>/dev/null 'print number_format("",0) . "\n";'
on our old PHP 5.1.6 Solaris 8 box (that we are transitioning off of)
returns 0.

Now, we're testing our code, and we run into this behavior change:
php -r 2>/dev/null 'print number_format("",0) . "\n";'
on our new RHEL5 with 5.3.1 from the REMI repository returns NULL. Is
this the default behavior expected? If so, why did this change happen?
If not, where did we go wrong?

Reproduce code:
---------------
php -r 2>/dev/null 'print number_format("",0) . "\n";'

Expected result:
----------------
We expect to see 0 returned, not NULL.

Actual result:
--------------
NULL is returned.
