My content type has a node reference field that allows users to enter an unlimited amount of nodes in. I need to programmatically change what comes first in this list.

Using the code below I’m able to obtain the data from the field.

$  node = \Drupal::entityTypeManager()->getStorage('node')->load($  function); $  focus = $  node->field_focus_area->getValue(); 

And it produces:

array(2) {   [0]=>   array(1) {     ["target_id"]=>     string(2) "31"   }   [1]=>   array(1) {     ["target_id"]=>     string(3) "161"   } } 

In order to rearrange it I tried doing

$  newOrder[0] = ['target_id'=> 161];  $  newOrder[1] = ['target_id'=> 31];  $  focus->field_focus_area->rekey($  newOrder); 

But it was then when I realized that rekey was a protected function so I could use it. How would I programmatically rearrange the deltas (if that’s what you’d call it) of an entity reference field programmatically?
