When using MapScript to render the map, the saveImage and saveWebImage
calls take a transparency argument that has priority over the mapfile
setting.  See the saveImage() and saveWebImage() functions in the
imageObj class docs at
http://www2.dmsolutions.ca/mapserver/php_mapscript/php_mapscript_docs.html

And to use the transparency value from the mapfile, you can use
something like this:

  $url = $image->saveWebImage($map->transparent, $map->interlace);
