Add 2 arrays in PHP

Question

I have two arrays that look like this:

array 1:

    Array
    (
        [0] => name
        [1] => age
        [2] => job
    )

array 2:

    Array
    (
        [0] => name
        [1] => toan
        [2] => age
        [3] => 21
        [4] => job
        [5] => coder
    )

Now, I would like to take the values from keys 0, 2, 4 and make those values their own keys that point to the values in keys 1, 3, 5 in the array, like so:

Array
(
    [name] => toan
    [age] => 21
    [job] => coder
)

What is simple and fast way to do this?

Well, implement a small function using a loop and iterate through the second array using array_keys() and array_key_exists() or is_set()... — arkascha

Assuming that value is followed by key in array 2, which it would need to be to use array 1 anyway, you don't need array 1:

foreach(array_chunk($array2, 2) as $pair) {
    $result[$pair[0]] = $pair[1];
}
print_r($result);

array_combine($array1, array_diff($array2, $array1));

Nice! I normally go for something that doesn't require a loop but that escaped me.
