The array will be casted to a boolean, like if you would use if((bool) $array) { }

false is returned when the array is empty (e.g. $array = [])

true is returned as soon as at least one key is set in the array (either like ["some value"] or ["data" => "value"]

You can simply test what the returned value will be by using

var_dump((bool) $your_array);
