Converting arrray values to integer from request in laravel

Question

I want to array_diff() two arrays in Laravel. The first array looks like this:

    array:4 [
  0 => 7248
  1 => 7249
  2 => 7250
  3 => 7251
]

the second one:

array:4 [
  0 => "7248"
  1 => "7249"
  2 => "7250"
  3 => "7251"
]

this one I get with $request->request->get('ids', []);.

How can I convert one array to either strings or integers? As these arrays can grow large, I don't really want to convert every single value one at a time.

Update:

array_diff() is doing it's job, altough there are strings vs. integers.

Thanks in advance!

You don't need to convert anything. array_diff() uses (string) $item1 === (string) $item2, so it works right out of the box. — Joel Hinz

$newArray = array_map('intval', $request->request->get('ids', []));

This code will convert your string fields to int so you can compare.

Hmmm why is the downvote for this answer? It will work for OP's question.

Actually, that's correct answer, because it answers on OP's question precisely that is "How can I convert one array to either strings or integers?". Saying that array_diff won't work was just a distraction :)

Thank you. Although its not really necessary, but it makes the resulting array better. :)
