You should use ord() on each of the $cont{} ones..
printf ("%02x %02x %02x %02x", ord($cont{0}), ord($cont{1}),
ord($cont{2}), ord($cont{3}));
That'll probably work much better..
...
PHP != C++, or C for that matter.. C was designed to be as close as possible
to ASM, but high-level.. PHP is designed to be an easy to use web
application language.. One char in PHP is a string with the length of 1, not
a small integer.. Meaning that 'a' != 67 in php.. In C they would be equal..
Strings will be converted to integers by php, but you won't get the ascii
code, you'll get something like the results of atoi() or something like
that..
