I think, hexdump manipulation functions are very useful string functions.
I have been using hexdump(), packhex() and smart hex functions,
written on PHP, and including it in many projects more than 2 years,
and at last I've implemented it into php core.
It helps in debugging:
- communication protocols
- any algorithms with binary data
- any kind of logging
etc

why to the core? because `pack()` function is already in the core. It's
good function, but it's a little bit complex for every minute using.

hexdump manipulation is like md5, crc32 etc. It is every minute
function, I think.

Well, what about PEAR package then?
I don't see any certain reasons to add them into the core, if they can be easily implemented in PHP.
While I can understand your needs, I'm against adding to the core each & every function that can be 
useful for a couple of persons using PHP, especially if this function can be implemented in PHP.

So -1 from me.

Yes, sounds like great one for PEAR. Especially that it seems to be 
debugging function, i.e. not performance-critical, so no problem doing 
it in pure PHP.

Ok, let's do this way. I'll alter the sources into PEAR.
