How to update value by Events in CodeIgniter 4

This is not tested but I think you need to pass the array by reference.

PHP Code:

Events::on('add_value_to_array', function(&$array) {
    error_log("add_value_to_array" . PHP_EOL, 3, "events.txt");
    $array[] = 'new';
}); 


You can try your way with array_pust but then you making an extra function call.

What did you Try? What did you Get? What did you Expect?
