Description:
------------
The following tests were all ported from 5.3 and behave differently 
on 6.0. There are two issues with the test results. Firstly, they 
return different values from 5.3 - this may not be a problem if 6.0 
is actually making them more consistent.

However within a given function some invalid arguments return 
bool(false) and other examples return NULL. Perhaps we should be 
consistent and always return one or the other? It would make 
documenting the function easier anyway [:o)

Reproduce code:
---------------
Here is an example using fopen() - notice the different return values:
