How to combine 2 arrays into 1 array

Question

I have 2 arrays like that:

array1
      (
        [0] => Array
                   (
                     [id] => 133
                   )

        [1] => Array
                   (
                     [id] => 134
                   )

      )

array2
      (
        [0] => 1
        [1] => 2

      )

My problem is: how can I combine two arrays into one array like:

array3
      (
        [133] => 1
        [134] => 2

      )

Thanks for any help :D

Try

$array3 = array();
foreach ($array1 as $key => $value) {
  $array3[$value['id']] = $array2[$key];
}

$array3 = array_combine(array_map('current', $array1), $array2);

What is "current" in the map?

deceze Over a year ago

It takes the current (first) element from the child array, in essence flattening the array.

Nice tip deceze. This is a much tidier solution.

I've done it like this:

<?php
    $arrayOne = array(
        array("id" => 133),
        array("id" => 134)
    );
    $arrayTwo = array(1,2);
    $arrayThree = array();
    foreach($arrayOne as $index => $value){
        $arrayThree[$value['id']] = $arrayTwo[$index];
    }

if you do a

print_r($arrayThree);

now you will get your third array:

Array
(
    [133] => 1
    [134] => 2
)
