Etch repositories

One of my servers runs Debian Etch, very old distrib. To upgrade php on this server I need etch repositories. All of them are on archive Debian server:
deb http://archive.debian.org/debian/ etch main non-free contrib 

deb http://archive.debian.org/debian-security/ etch main non-free contrib 

deb http://archive.debian.org/debian-volatile/ etch main non-free contrib
