I was bored so came up with this.

<?php
$hexvals="40 40 51 32 35 2C 33 35 33 33 35 38 30 31 37 37 38 34 30 36 32 2C 41 31 30 2A";
$hexarr=explode(" ",$hexvals);
$sum=0;
foreach ($hexarr as $hexval) {
    $decval=hexdec($hexval);
    $sum+=$decval;
}
$hexsum=strtoupper(str_pad(dechex($sum),4,0,STR_PAD_LEFT));
echo $sum . " >>> " . $hexsum;
?>

Try to do your own homework projects in future. :wink:
