Hi!
I've always thought isset() was quite ugly. For something I use quite
frequently for checking the existence of array keys, I feel it is too
many keystrokes, and is ugly.
So, I decided I would create a shorthand for isset().
One option suggested was a new operator, 'expr ??', which I don't like
the idea of very much. I would also have liked 'expr ?', but that would
conflict with the ternary operator, 'expr ? expr : expr'. Then, I had
the idea of '? expr', but that also caused a conflict. So I settled on
'? ( expr )', which is used like this:
if (?($_POST['credit_card_no'])) {
// ...
} else if (!?($_POST['use_paypal']) && ?($_POST['bank_acc_no'])) {
// ...
}
And since it doesn't break the ternary operator, like this:
$number = ?($x)? intval($x) : 0;
I quite like how it combines with !, so !?() tests for non-existence,
and ?() tests for existence.
It's quite trivial, but it would save me (and probably many others)
time, and I think it would add some extra character to PHP, with its
quirky syntax. :)
Patch attached. Thoughts welcome.
