Hi all,

I have a string of 0s and 1s, for instance "1101000010101111". I want to reverse each group of 8 chars in it. For the above example: "0000101111110101"

The application is a string of bits, and the bits of each byte must be reversed.

I'm looking for the fastest way to achieve this, on strings of small length (up to a few hundred chars). The obvius solution, which is pretty fast is with substr() on each 8 bits (in a for loop). Any better ideas ?

Thanks in advance
