PHP, how to use instanceof on an array

I did a var_dump on a variable called $row, and I got this:

array (size=1)
  'name' => string 'Glenn' (length=5)

Select all Open in new window

So I know it is an array. But when I do this:

echo $row instanceof array;

Select all Open in new window

I get a syntax error: Parse error: syntax error, unexpected 'array' (T_ARRAY).

Now I know there is the is_array, but is there no way I can use instanceof on an array?
