[ciapug] php SuperGlobals issue

[Tony Bibbs]

I haven't researched as to why this is but I've noticed that the 
available supergloabls be different on different setups.  I've 
particularly noticed this when developing code that needs to run on both 
*nix and Winders.  I've even seen difference between two different 
Winders boxes.  I'm sure this is explained on php.net somewhere but my 
experience is that if you depend on a superglobal being set you need to 
rely on the phpinfo() output.
