在PHP中将嵌套（多维）数组更改为key => value对

Question

I have an multidimensional array that looks like this:

Array
(
    [0] => Array
        (
            [ClientID] => ec2173de2134fdsfg4fsdffcb4b5205
            [Name] => ABC Widgets
        )

    [1] => Array
        (
            [ClientID] => e5dfgfdg2d760f640aadfgdfgdfg47b
            [Name] => Acme Co
        )

    [2] => Array
        (
            [ClientID] => b9dfgsdfg419085c3sdgffdsgfdg313
            [Name] => 4321 Corp
        )

)

I would like to change to the following:

Array
(
  ec2173de2134fdsfg4fsdffcb4b5205 => ABC Widgets
  e5dfgfdg2d760f640aadfgdfgdfg47b => Acme Co
  b9dfgsdfg419085c3sdgffdsgfdg313 => 4321 Corp
)

What is the best way to do so? Also, would I be better off storing the array in its original format and converting to other formats as needed? Thank you for any assistance

Answer 1

$flat = array();
foreach($multidim as $item)
    $flat[$item['ClientID']] = $item['Name'];

Whether you'd be better off storing the original form cannot be answered generally. You should store it if you need it.
