Re^2: Multiple Conditional Statements

If you like a more direct approach,

That's a perfectly valid approach, but how is it "more direct"? (And "more direct" that what for that matter?)

You have:

An auxiliary boolean variable;
An auxiliary array (... of references which have to be taken);
Two nested loops;
A callback function (from a module);
An array slice;
n(n+1) dereferences;
n(n+1)/2 comparisons;
And it doesn't even short-circuit if the first two variables compared are the same.

That's the strangest definition of "more direct" I can think of :)

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.
