ProjectionObject Conversion Problem

MS_Users,

I'm converting my mapscript code from cgi to php. I was using the following
proj4 commands in cgi to convert from Latitude / Longitude in Radians to
meters:

	$pj = proj::pj_init($ProjParnNum, \@LatLongProjParm) ;

	$in = new projUV();
	$in->{v} = $LatRad;
	$in->{u} = $LngRad;

	$out = proj::pj_fwd($in, $pj);

Attached is the php code I wrote to try to perform the same conversion using
Mapserver ProjectionObject but the results are not the same. I'm not an
expert at Proj4/Projections so any help would be appreciated.

Mapserver 4.10.1
PHP 5.1.6

	/** Results should be
	*	[x] => 668830  meters
	*	[x] => 177066  meters
	* but are
	*	[x] => 45386984.852019
    	*	[y] => -10739937.18402
	*/
