[SOLVED] Addin in HEXACECIMAL

[Tonic-_-]

Well anyways this has been on my mind for awhile not many good php examples for hex period but I want to add hex strings together...

 

like

 

$a = dechex(0x0055a048);

$b = dechex(0x08800000);

$hex = $a+$b;

 

That should e

echo $hex;

 

That is supposed to echo 08d5a048 but of course doesn't.

 

Figured you guys would know..

$a = 0x0055a048;
$b = 0x08800000;

echo dechex($a).' + '.dechex($b).' = ';

$hex = $a+$b;

echo dechex($hex);

or

$a = '0055a048';
$b = '08800000';

echo $a.' + '.$b.' = ';

$hex = hexdec($a)+hexdec($b);

echo dechex($hex);
