How to exit from array iteration functions (array_reduce) in PHP

Question

I'm having an array_reduce function which I am willing to exit when specific criteria is met.

$result = array_reduce($input, function($carrier, $item) {
  // do the $carrier stuff
  if (/* god was one of us */) {
    break; //some break analogue
  }
  return $carrier;
});

How do I achieve this? Or should I use foreach instead?

Answer 1

array_reduce is used to write functional-style code which always iterates over the full array. You can either rewrite to use a regular foreach loop to implement short circuiting logic, or you can simply return the current $carrier unmodified. This will still iterate over your full array, but it will not alter the result (as you said, this is more alike to continue)
