I'm not sure why this is still open as a documentation bug.

The string behavior is documented in:
http://www.php.net/manual/en/language.types.string.php

and the == and === behavior is documented in:
http://www.php.net/manual/en/language.operators.comparison.php

The conversation is useful. I know this because HTML form
parameters, MySQL result sets are strings even if they are
represent numbers.

But there some cases for which the conversation is not
useful. If the result is MAXINT, MININT or NaN, it would
be better not converting the operands and making a
string comparision. A warning message whould be also
useful.

this autoconversion is usefull when dealing with html form input
(for which php is used every once in a while afaik :)
as html has no numric input elements, just text

maybe it would make sense to have this behaviour configurable
in the ini file, but i'm afraid that this would only increase the WTF
factor even more

Ok, I accept this. But I don't think that is a good idea
to compare apples with pears with the answer 'yes they are
fruit' without any warning.

Ok, it should remain open as a documentation problem...

This is a defined behavior (and does have strong reasons). It's not a bug.
If you're interested in a byte-by-byte string comparison, you should use strcmp().
