How to separate keys of duplicate values in an array

Question

I have an $my_Array which is dynamic. What should i do to get $Final_array based on $my_Array.

    $my_Array = array(  
                ['arm'] => 'cc9f8eb4-e29f-44b4-8dcd-ac08e9b1faa6',
                ['min'] => 'cc9f8eb4-e29f-44b4-8dcd-ac08e9b1faa6',
                ['msk'] => 'cc9f8eb4-e29f-44b4-8dcd-ac08e9b1faa6',
                ['con'] => 'c72a7fb8-308a-482a-96d5-7a7853e16c49',
                ['ref'] => 'c72a7fb8-308a-482a-96d5-7a7853e16c49',
             ) 


   $Final_array = array
                (   'cc9f8eb4-e29f-44b4-8dcd-ac08e9b1faa6' => 'arm, min, msk',
                    'c72a7fb8-308a-482a-96d5-7a7853e16c49' => 'con, ref'
                )

why dont you write it yourself? It's not that hard. Come to learn and not to let other people write your code — Soundz

$data = array();
foreach( $my_Array as $key => $value) {
    if(isset( $data[ $value ] )) {
        $data[ $value ] = $data[ $value ] .', '.$key;

$Final_array = array();               
foreach($my_Array as $key => $value){
 if(array_key_exists($value, $Final_array)){

  $Final_array[$value] = $Final_array[$value]. ", ".$key;

 }else{

  $Final_array[$value] = $key;

 }
}
print_r($Final_array);        
?>

Output:

Array
(
    [cc9f8eb4-e29f-44b4-8dcd-ac08e9b1faa6] => arm, min, msk
    [c72a7fb8-308a-482a-96d5-7a7853e16c49] => con, ref
)

I tried to do this with one loop and failed, but hope its ok with you.

$new = array();
foreach ($my_Array as $key => $val) {
   $new[$val][] = $key;
}

foreach ($new as $key => $val) {
   $new[$key] = implode(", ". $val);
}
