For the record, name does not turn into 0, 1, nor TRUE here, but simply
becomes 'name' which is what you should have typed in the first place.
Set error_reporting(E_ALL) to get more details.

You are passing 'Europe' as $subcat, and then trying to treat it like an
array when you do $subcat['name'].
PHP will let you treat a string as an array of characters, if you insist.
At this point, PHP *does* turn 'name' into the index 0 because you can
only index strings as character arrays using integer indices.
$subcat['name'] => 'Europe'['name'] => 'Europe'[0] => 'E'
