I already complained about that issue several times on IRC
and now that it's time for PHP-5.1 to come, I'll just throw
this question/rant in...
Using is_a() throws a notice (E_STRICT IIRC) in PHP5, which
should be fine, because it was deprecated in favour of the
instanceof operator. But there's quite an ugly problem with
the instnceof operator - it needs the class to be checked
already loaded, while is_a() didn't -- *and* instanceof
let the script _die_ if there's no such class.
To replace
is_a($obj, 'ClassName')
calls one would need to write
class_exists('ClassName') && ($obj instanceof ClassName)
The point is, that I don't see the point why is_a() has been
deprecated (and replaced) by an operator that doesn't provide
the same functionality and can even be harmful (with fatal errors).
Regards,
Mike
