  array (
    'id' => '20110209172713',
    'Date' => '2011-02-09',
    'Weight' => '200',
  ),
  1 => 
  array (
    'id' => '20110209172747',
    'Date' => '2011-02-09',
    'Weight' => '180',
  ),
  2 => 
  array (
    'id' => '20110209172827',
    'Date' => '2011-02-09',
    'Weight' => '175',
  ),
  3 => 
  array (

foreach ($array as $key => $value) {
  $result[$key] = $value['Weight'];
}
$min = min($result);
$max = max($result);

echo " The array in Minnumum number :".$min."
";
echo " The array in Maximum  number :".$max."
";
