Change values from a array while iterating

Question

the array:

('abc', 'def', 'xyz')

foreach($arr as $item)
  // change $item here

Can I do this without creating a intermediate array?

...although in almost all cases I'd argue that reducing side-effects only increases program readability... — user166390

Use a reference.

foreach($arr as &$item)
