That PHP one is a port of a web-based javascript one:  
http://dean.edwards.name/packer/
It does a good job of minimising (and obfuscating) your javascript, but  
does require you to be a bit stricter with your coding. Ending lines with  
a ; is optional in js, but the packer requires it. As PHP coders, I would  
think that would be 2nd-nature anyway (was for me), but having to put a ;  
after a function or object definition is a little odd, and I had to go  
through quite a lot of code adding them for it to work. Prototype and  
scriptaculous code won't, from the standard distribution, work after being  
packed like this, although people have provided modified versions that do.
