[RESOLVED] sanity check

[sneakyimp]

Forgive me for posting such a stupid question, but am I correct in thinking this array_key_exists check is pointless:

		foreach ($arr as $key => $value) {
			if (blah_blah($key) && array_key_exists($key, $arr)) {
				$this->$key = $value;
			}
		}

Since we are doing a foreach loop on $arr, array_key_exists is ALWAYS AND FOREVER going to return TRUE, yes?

My faculties are much diminished today due to too much time in front of the workstation.

Looks unneeded to me -- unless by some chance blah_blah() modifies $key, and it's passed by reference to blah_blah().

I agree with NogDog; the only issue is if blah_blah messes with the value of $key so that there's a need to check that it's still a key in the array.

Thank you, gentlemen.
