Try the following:

foreach($post as $key => $value) {
 foreach($value as $print => $key) {
     if (is_array($key)){
         foreach($key as $print2 => $key2) {
          echo "<br>".$key2;
          }

     }else{
     echo "<br>".$key;
     }
   }
}

The string method for the array should return "Array".

It looks like you want to view the array for debugging purposes. var_dump()- your friend:)
