sprintf("%04x", $x)

[powers]

%x is hexadecimal representation
but what is %04x?

this function is outputing the value of $x as what?

so if x=234sd
what should the ouput be?

how about x=2234?

thanks.

Pad with up to 4 zeros, I think.

if i have a number

56908

what is the output?

6908? or 56908?

and i imagine that the number 32 becomes 0032

correct?

but the 'x' says to use hex right?

is it padding as an int or hex? i.e, do i pad the int and get the hex of that, or get the hex of the int and pad that up to four?
