After numerous hours of trying to actually receive a hexadecimal digit from dechex, I decided to
give it a go myself.
I kept trying to do bitwise comparisons on the result however I was comparing strings,
<?php
function dectohex($dec){
$code='return 0x'.dechex($dec).';';
return eval($code);
}
?>
This actually returns a hexadecimal value, not a string representation.
Hopefully this saves someone else a couple of hours.
