Can I display the array key and value without using foreach?
$down = array (
    "file.rar" => $l->get()->fileDesc(),
    "file1.rar" => $l->get()->clientDesc()
);

foreach ( $down as $key => $value )
     $data .= $key . ' = ' . $value . '<br/>';

//echo $data;
    file.rar = File Description One
    file1.rar = Client Description

function print_array($down) {
   $data = '';
   foreach ( $down as $key => $value )
      $data .= $key . ' = ' . $value . '<br/>';
   return $data;
}

<?php
  $data = print_r($down, true);
?>
