Checking for empty arrays: count vs empty

Question

This question on \'How to tell if a PHP array is empty\' had me thinking of this question

Is there a reason that count should be used instead of e

Answer 1

Since a variable parsed as negative would return int(1) with count()

I prefer ($array === [] || !$array) to test for an empty array.

Yes, we should expect an empty array, but we shouldn't expect a good implementation on functions without enforced return types.

Examples with count()

var_dump(count(0));
> int(1)
var_dump(count(false));
> int(1)
