<code class="php">array (0 => 
  array (
    'id' => '20110209172713',
    'Date' => '2011-02-09',
    'Weight' => '200',
  ),
  1 => 
  array (
    'id' => '20110209172747',
    'Date' => '2011-02-09',
    'Weight' => '180',
  ),
  2 =>

    'Date' => '2011-02-11',
    'Weight' => '195',
  ),
)</code>

<code class="php">$weights = array_column($array, 'Weight');</code>

<code class="php">$minValue = min($weights);
$maxValue = max($weights);</code>

<code class="php">$weights = array_map(function($row) { return $row['Weight']; }, $array);

$minValue = min($weights);
$maxValue = max($weights);</code>

<code class="php">$minValue = array_reduce($array, function($minimum, $current) {
    return min($minimum, $current['Weight']);
}, PHP_INT_MAX);</code>
