New Comment:
treat it as feature request if it helps you sleep at night. However this issue
is
critical in face of current mailicous code boom. Eval (by base64_encode etc)
does
not allow for any scanning and detection. This funcionality of php had begun
its
downfall really. People are migrating to other languages just because
infections
there are rare and code cannot be just like that obfucated!

"eval is not a function but language construct" - that might be the reason why
disable_functions don't work on it now but that does not mean it could not or
should not.
I would not dismiss this isssue so easily. Eval problem caused that php is
currently (almost) only one language is so often infected. It allows for
attacker to hide code, purpose, use ecodings (like base64) to diminish any hope
of detection by searching for common traits (like antivirus software does).
Eval is a functionality of php and could be disabled if apropriate
modifications
to php source code were made.

Why can't you simply add a new core directive for disabling this language
construct?

as I said, eval is not a *function*, so disable_*functions* has no effect to
eval..

A reason why a bug exists is not a reason why it is not a bug.

eval is not a function, if you want to disable it, you may refer to Suhosin
