For change key of multi dimensional array according to value of inner array just put below function into your script and use it..

{

function array_keyBy($array , $keyBy)

{

if(!empty($array) && count($array) >0 )

{

$tempArray = [];

foreach($array as $key => $value)

{

if(!is_array($value))

{

$value = (array) $value;

}

if(isset($value[$keyBy]) && $value[$keyBy]!='' && !is_array($value[$keyBy]))

For example: - I have an array as like below and i want to change key of multi dimensional array by value of name key.

$person = array

  (

  array(

'name' => 'Romal',

'Age' => '34'

),

  array(

'name' => 'Anil',

'Age' => '24'

),

  );

Now i call above function like below:- 

 $newpersons = array_keyBy($person,'name'); 

Now output of $newpersons is like below..

Array
(
    [Romal] => Array
        (
            [name] => Romal
            [Age] => 34
        )

    [Anil] => Array
        (
            [name] => Anil
            [Age] => 24
        )

)
