Convert html color to rgb?

[Anon]

How can i convert html color code, for example #FF0000, to rgb components. For example:
#FF0000 -> 255, 0, 0

And ofcourse back again:
255, 0, 0, -> #FF0000

In java its simple:

int r = Integer.parseInt(param.substring(0, 2), 16);
int g = Integer.parseInt(param.substring(2, 4), 16);

int b = Integer.parseInt(param.substring(4, 6), 16);

But unfortunally php has no parseInt() function.

Best regards,

No, but it does have a hexdec() function

Thanks! The output of hexdec is a decimal representation of the hex. Is it possible to extra the rgb components from the decimal number?

Yeah, but it's probably easier to extract the hex substrings as you were before and hexdec() each component seperately.

Thanks, works like a charm! 😉
