At least you only have ONE implementation of PHP to contend with.

When I did similar in Javascript it took me TWO BLOODY DAYS to work out
why exactly the same code worked in Firefox and not in IE6.

And it was EXACTLY the same issue. comparing what I ASSUMED were
numbers, but they got converted to strings by IE6,

But not by firefox.

It took me one and a half days to pin the thing down, and half a day to
find a construct that actually did the same thing in both browsers.

sheesh.

I even looked up the spec. It didn't cover the case. casting is
explicitly defined in ASSIGNMENTS, but not in COMPARISONS.

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to lead are elected by the least capable of producing, and where the members of society least likely to sustain themselves or succeed, are rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers.
