[Solved] PHP reformatting array

by 


$currentKey = '';
$newArray = array();
foreach ($array as  $val) {
    if (!is_array($val)) {
         $currentKey = $val;
    } else {
         if (isset($newArray[$currentKey]) && is_array($newArray[$currentKey])) {
             $newArray[$currentKey][] = $val;
         } else {
             $newArray[$currentKey] = array($val);
         }
    }
}

I hope you understand what is happening here?
And of course it’ll work only with arrays like first from your question.
