var_dump(is_a([], "array"));
The above code displays "false".
But,
echo gettype([]);
Displays "array".
Am I doing something wrong or missing out on something here?

is_a() function checks if the object is of this class or has this class as one of its parents
To check if something is an array, you should use is_array().
Based on the question and what has been described in the comments, it sounds like you're looking for a way to identify if something (i.e an array or object) is iterable.
In PHP, this can be achieved with is_iterable(), which will return true if the passed-in parameter supports iteration via foreach.
From the docs:
Verify that the contents of a variable is accepted by the iterable pseudo-type, i.e. that it is either an array or an object implementing Traversable
In the case of the array you mentioned in the question:
is_iterable([]));
Outputs:
bool(true);
