Hi!
Let me turn your question around: Why on earth would someone restrict a
function to int when string works just as well?
function int foo_flexible(scalar $x) { return $x + 42; }
$foo = foo_flexible($value);
Now let's think - what happens if $x is *not* scalar? So the real code
would be like this:
function foo_flexible(scalar $x) { return $x + 42; }
if(!is_scalar($value)) {
$foo = foo_flexible($value);
} else {
// ok, what do I do now?
}
And so for each instance. Ugly.
That said, I'll be using
function foo($x) { return $x + 42; }
anyway and let PHP warnings take care of the rest ;-)
Amen to that.
