PHP - Create ArrayIterator with offset

Question

Maybe silly question, but I have an array and I would like to create an ArrayIterator but with an offset.

Example, I've the following array :

$fruits = [
  1 => 'banana',
  2 => 'apple',
  3 => 'orange',
  ...
  20 => 'raspberry'
]

My offset is 3.

I want to create an ArrayIterator with the $fruits array and the $offset. How can I do that ? I don't understand the ArrayIterator doc'. There is the OffsetSet() method but I don't understand how it works

You mean to skip the first x elements in an array, yes? Or what do you mean by offset? — Definitely not Rafal

How to skip the 1st key in an array loop? (you should be able to change the first given answer to skip the first x elements) — Definitely not Rafal

“Yes that's it, ignore the first x elements” - then you appear to have misunderstood what offsetSet does to begin with. See here for an explanation of what it actually does: geeksforgeeks.org/php-arrayiterator-offsetset-function — C3roe

Either skip while you're looping or use array_splice to create a new array from your offset onwards.

$obj = new ArrayObject( array_slice($fruits, 3) );
$it = $obj->getIterator();
