OK - But I am wondering why nobody has said that on the firebird support list!
Certainly not so long ago the fix for client niggles was to ensure you were
using the same version, but I think that the idea that there could be
different copies of the same version probably got missed? The usual fix was to
ensure that there was only ONE copy of GDS32.dll in the lookup path.

? - Old clients need to be replaced with a new one if the target server
changes? And in that case every additional application needs updating with the
correct copy of the client - which is why 'personally' I'd prefer to keep to a
single client installation. And if the firebird server version was updated
(FB2.5 is coming), but the PHP client got missed THEN I can see a potential
time bomb?

As I have said - my experiences go back into Interbase only times, and there
were a number of distinct 'do not does' but that may well have been sorted in
the meantime. Again - it would be nice if someone would simply say - 'Oh yes
that was sorted in 1.0.x' or when ever. Although I suspect that it was never
formally be investigated since the 'one copy' rule fixed the original problems
and older users never tried running more than one?
