How to check if variable is array?... or something array-like

In PHP, you can use the "is_array" function to check if a variable is an array. For example:

If you want to check if a variable is something array-like, you could use the "is_iterable" function, this function checks if the variable is an array or an object that implements the Traversable interface, starting from PHP 7.1.

<div class="alert alert-info flex not-prose"> <span class="hidden md:block">Watch a video course </span> Learn object oriented PHP</div>

You can also use the instanceof operator to check if the variable is an instance of the ArrayObject or ArrayIterator classes, but it's less recommended.
