While this is implied in the definition I have verified (PHP 5.5.38, 7.1.32, 7.2.23 and 7.3.10)
that:
is_array(null) == false
So there is no need for this:
if (isset($arr) && is_array($arr)) { /* ⦠*/ }
The same can be accomplished with:
if (is_array($arr)) { /* ⦠*/ }
The value null is often a special case so I think this should be included in the documentation.
