[UMN_MAPSERVER-USERS] Does shapeobj->union exist in php-mapscript

[Paul Moen]

I get the following error.

    PHP Fatal error:  Call to undefined method ms_shape_obj::Union()

By doing the following.

    $wktshp1 = ms_shapeObjFromWkt($wkt1);
    $wktshp2 = ms_shapeObjFromWkt($wkt2);
    
    $newshp = $wktshp1->Union($wktshp2);

PHP/Mapscript docs say.
shapeobj Union(shapeobj shape)
        Returns a shape object representing the union of the current
        shape object with the one passed as parameter.
        Only available if php/mapscript is built with GEOS
        library.

GEOS is built in.

Does union exist in PHP/Mapscript?

Thanks,
