Get max value from attributes values

[tips007]

use the code below

<? php 
for ($i=0, $n=sizeof($order->products); $i<$n; $i++) { 
   for ($j=0, $n2=sizeof($order->products[$i]['attributes']); $j<$n2; $j++) {
      echo zen_output_string_protected($order->products[$i]['attributes'][$j]['value']);
   }
}
?>

you'll get the result
638

if you add the <p> to it, such as echo zen_output_string_protected($order->products[$i]['attributes'][$j]['value']) . '<p>';
you'll get
6
3
8

now i want to get the max number from 6, 3, 8
any one could help?

$attrib_max = 0;
for ($i=0, $n=sizeof($order->products); $i<$n; $i++) { 
   for ($j=0, $n2=sizeof($order->products[$i]['attributes']); $j<$n2; $j++) {
      $attrib_max = ($attrib_max > $order->products[$i]['attributes'][$j]['value'])? $attrib_max: $order->products[$i]['attributes'][$j]['value'];
   }
} 

$attrib_max will end up as the max of the attribute values.

you are a genius!
thank you

A simpler version of the comparison uses the PHP max() function:

      $attrib_max = max($attrib_max, $order->products[$i]['attributes'][$j]['value']);
