Replacing values in array from another array

Question

I have this array structure:

And this array structure:

Array
(
    [0] => stdClass Object
        (
            [fs] => SQ
            [iata] => SQ
            [icao] => SIA
            [name] => Singapore Airlines
            [active] => 1
        )
    [1] => stdClass Object
        (
            [fs] => VX
            [iata] => VX
            [icao] => VRD
            [name] => Virgin America
            [active] => 1
        )

)

Basically what I want to do is take the first array and find its matching IATA/FS code in the second array and replace it with the ICAO code. So for example, with the first array, I want to replace the VX with VRD. I want to be able to apply the same concept to other airline/routes, too...not just VX.

If it helps, I'm getting this information from a JSON return: http://pastebin.com/2w0kQQ26

I looked into array_replace(), but because my PHP skills are almost nothing, I didn't know how to continue.

If someone can point me to the right direction, I'd appreciate it.

With array1 being your first array and array2 being the second array you described.

$comp_arr = array()
foreach ($array2 as $arr) {
  $comp_arr[$arr[fs]] = $arr[icao];
}

foreach($array1 as $key => $arr){
  if(array_key_exist($arr[carrierFsCode], $comp_arr){
       $array1[$key][carrierFsCode] = $comp_arr[$arr[carrierFsCode]];
  }
}
