Library for converting projection transformation in PHP

Question

I would like to transform data from lat/long ETRS89 to y/x UTM ETRS89 through PHP.

Any ideas?

Answer 1

A internet search on PHP and projection turned up a PHP port for PROJ.4.

proj4php

The page says that it's a translation from a Javascript version of PROJ.4. I'm not familiar with it so I can't give you any more details.
