unix socket for mysql in db

this is no feature request, just a 'why-is-this-constructed-like-this' question... some cut/paste from the parseDNS function comments: /** * protocol: Communication protocol to use (tcp, unix etc.) * phptype://username:password@protocol+hostspec:110//usr/db_file.db */ how can anyone use a unix style path in the hostspec when the next control char is a slash? i would like to use unix sockets in pear db, i would like to write a patch, i would like a discussion how to implement :) with kind regards, Joffrey van Wageningen PLAYcollective
