Unsupported operand types? How to solve?
I am getting Unsupported operand types only when $array01 is empty... How do I get around this?
//Array for the a newly create group
$newgroup = array();
$newgroup = array_add($newgroup, $justcreated_group, '1');
//Array for existing group selections
$array01 = Input::get('group_ids');
//Merge the 2 (give me Unsupported operand types when array01 is empty)
$merge = $newgroup + $array01;
$finalarray = array_keys($merge);

@RachidLaasri that give me the following ErrorException (E_UNKNOWN)
array_merge(): Argument #2 is not an array

Is it possible, that $array01 isn't empty, but null, when you get the error?

Use this line to see the content of the $array01 variable, i think it's either empty or not an array.
dd($array01);

@RachidLaasri @Lily Belle Its null. Any quick fixes?

$array01 = Input::get('group_ids') == null ? [] : Input::get('group_ids');
Level 25
Even simpler:
$array01 = Input::get('group_ids', []);
