DRY:

  $frq = array(
    12 => array(13.4, 17.4, 20.0),
    13 => array(3.5, 6.7, 17.3),
    19 => array(3.1, 194.45, 10.909)
  );

Since PHP 5.4:

  $frq = [
    12 => [13.4, 17.4, 20.0],
    13 => [3.5, 6.7, 17.3],
    19 => [3.1, 194.45, 10.909]
  ];

        ^^
  echo '<pre>' . print_r($frq, true) . '</pre>';

<http://php.net/print_r>

With the Xdebug extension enabled,

  var_dump($frq);

will generate the output using a fixed-width font by default, and you have 
more control over the output, such as the nesting level.

Avoid this in PHP programs unless you are sure that you want what follows to 
be sent to the standard output.
