do_action_ref_array( $tag, $arg )
I can’t wrap my head around this one. If the $tag is the particular function, should the $arg be array arguments called up from that particular function or are they reference to some other function that returns a number of array values (arguments) that are used in the $tag function?
Oh boy, my brain almost seized. I think I’m over complicating things.
Can someone maybe please explain this function to me in human language with a simple example?
