<?php
         dl('php_mapscript.dll');

         $map=ms_newMapObj("C:/OSGeo4W/apache/htdocs/xxxx.map");

         //$roate=$map->setRotation(90);
         $roate=$map->setRotation(0.00000001);

         //************** here you see, even with a small angle, the  
map could not   rotated as expection
         //echo $roate;
