PHP中的数组映射

Question

I having two arrays say,

$array1 = array("code" => "E0089",
                "desc" => "some description");

$array2 = array("code" => "Code",
                "desc" => "Description");

resultant array should be,

$result = array("Code" => "E0089",
                "Description" => "some description");

In short, I want to map two arrays and create third array.

Answer 1

short and simple: array_combine()

just use it like this:

$result = array_combine($array2, $array1);

Answer 2

If the arrays are already in right order:

$result = array_combine($array2, $array1);

Otherwise, you will need to do some looping:

$result = array();
foreach ($array2 as $key => $val)
  $result[$val] = $array1[$key];
