hexadecimal strings

[Anon]

HI,

other that writing my own function does any one know a quick way of getting a variable that contains hexadecimal data to stay as an integer as opposed to a string ?

When I cast to an int it zeros the values as it has letters, and including 0x at the beginning doesn't seem to alter the outcome.

Thanks in advance

hexdec() converts a string from hexidecimal to decimal.

Hi Chad,

yeah I di that but all the in built functions that take decimals and convert to hex return them as a string :0( and I need to do maths type stuff, ehn I cast I get 0 or if I am lucky 1.

Thanks for your help though

Yeah,

First use hexdec(), then force it into an integer.

E.g.

$hex_num = "FF";
$dec_num = hexdec($hex_num);
$int_num = (int) $dec_num;

$int_num should now be an integer

Cheers!
