PHP puts most of its functions into a big flat global namespace.
That leads to short function names - but creates a namespace
minefield for programmers.
Lots of the functions are legacies from the days before PHP
got object-oriented features.
For instance we currently have:

together with speed of coding in mind and therefore contains quite a few

Hi,
I'm linking into a library that has a global constant with the same
name as one in my application. My references to the constant are
being linked to the value in the library instead of the one in my
source file. Both constants are extern so I'm assuming it's undefined
which value I get. Obviously this is one of the reasons why...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
