 * Hello,
    In a plugin file there is an action defined as follows. It contains a
   parameter of type array as you can see:
 * `do_action('vse_da_update',$id,$data[$rkey],$status);`
 * I’m trying to handle this by reaching it in function.php. However, I cannot reach
   it. am i making a mistake? Is the parameter as an array being accessed in a different
   way?
 *     ```
       add_action('vse_da_update', 'new_vse_da_update', 10, 2);
       function new_vse_da_update ($id, $data){
       $new_value[$id] = $data[$rkey];
       }
       ```

 * This just means that the action is passing whatever value is inside `$data[$rkey]`
   as a variable. It will be a normal single variable in the callback function that
   you can access, with whatever name you choose:
 *     ```
       add_action('vse_da_update', 'new_vse_da_update', 10, 2);
       function new_vse_da_update ($id, $data){
       	$new_value[$id] = $data;
       }
       ```
   
 * This is the same as if you pass a value to a function:
 *     ```
       funtion do_something( $value ) {
       	echo $value;
       }
   
       $data = [
       	'key' => 'value',
       ];
   
       do_something( $data['key'] ); // 'value'
       ```
