How to reset indexes in array_diff result?

Question

I have two arrays: Array ( [0] => 2 [1] => 3 ) and Array ( [0] => 2 ).

I want to get the value, which is not in second array. So I have used the array_diff function but my result will get Array ( [1] => 3 ) Actually this is the result. But a small problem here, its position is (key) 1. I want the result in to a new array starts from 0th position, i.e., Array ( [0] => 3 ).

How can I achieve this?

Could you explain why having the original keys in place causes a problem? — salathe

you can use array_values(array_diff($arr1, $arr2)); if order doesn't matter

You should run array_values() on the result and this would give you a new array with indexes starting at 0.

This is a known shortcoming of array_diff(), check the php docs.
