php values of one array to key of another array [duplicate]

Question

I have 2 arrays

$arr1 = Array
(
    [0] => 12
    [1] => 4
    [2] => 8
    [3] => xx
    [4] => 1
    [5] => 1year
    [6] => 7
)
$arr2 = Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => 7
)

I want to create a new array with the values of a2 as keys in $arr1. My resultant array should be like this

$arr3 = Array
(
    [1] => 12
    [2] => 4
    [3] => 8
    [4] => xx
    [5] => 1
    [6] => 1year
    [7] => 7
)

@Pekka how to array_combine($arr2, $arr1)? ;)

$arr3 = array_combine($arr2, $arr1);
print_r($arr3);

Next time please consult the manual first.

You are very clever to snidely make your point by using a word that is not in the dictionary and a sentence that would make a grammar book curl its pages in horror ;)
