Hi Ian,

<?php
        $projInObj = ms_newprojectionobj("init=epsg:4326"); original 
epsg code
        $projOutObj = ms_newprojectionobj("init=epsg:23033"); 
destination epsg code
        $poPoint = ms_newpointobj();
        $poPoint->setXY(13, 38); //original coordinates
        $poPoint->project($projInObj, $projOutObj);       
        echo $poPoint->x.",".$poPoint->y; //echo new coordinates
