This issue arises from the loose typing in PHP with the introduction of
first class boolean type (the true and false keywords), from my
understanding the sematics being applied here are as follows (poetic license
== is (has become?) a boolean logic operator, dealing in terms of 'true'
and 'false' values, so its terms are type cast to either 'true' or 'false'.
When applied to strings, a 'false' string is zero length or contains '0',
all other strings are 'true'.
[please dont ask 'what if the string is NULL... ;-)]
If you dont want your terms to be treated as (type cast to) boolean values
use the strict equallity operator ===

The manual doesnt seem very clear on this at all, but == behaves something
like ^(A xor B)
