Rodolfo,
I don't dare to oppose Andy, I believe there is a solid justification
behind his statements, but note that:
1. This post concerns the previous versions of MGOS and FDO (I do not
say that it makes difference, in fact I am not aware of changes from FDO
3.3.0 to 3.3.1)
2. Since Mapguide connects to data in an uniform manner - thru FDO,  and
you are able to accomplish your task with SDF, then it depends only on
capabilities of the FDO provider if you will succeed with SHP or any
other format
I am sorry, if I have not been helpful to you

Ivan ,
I have used as a template the redlining module from PHPSAMPLES package.
Here is part of the code :

.........
    $map = new MgMap();
    $map->Open($resourceService, $mapName);
    $mylayers = $map->GetLayers() ;
    $mylayer = $mylayers->GetItem ($layerName);
    $ftrclassname = $mylayer->GetFeatureClassName();
    $batchPropertyCollection = new MgBatchPropertyCollection();
    $propertyCollection = MakePoly($use,$plabel,$owner, $polydef);
    $batchPropertyCollection->Add($propertyCollection);
    $cmd = new MgInsertFeatures( $ftrclassname,
$batchPropertyCollection);
    $featureCommandCollection = new MgFeatureCommandCollection();
    $featureCommandCollection->Add($cmd);
    $featureService->UpdateFeatures
($myResourceID,$featureCommandCollection,false);
.......

  function MakePoly($puse,$pplabel,$powner,$polystring)
  {
    $propertyCollection = new MgPropertyCollection();
    $ownerProperty = new MgStringProperty("Owner", $powner);
    $propertyCollection->Add($ownerProperty);
    $useProperty = new MgStringProperty("Purpose", $puse);
    $propertyCollection->Add($useProperty);
    $labelProperty = new MgStringProperty("Label", $pplabel);
    $propertyCollection->Add($labelProperty);
    $wktReaderWriter = new MgWktReaderWriter();
    $agfReaderWriter = new MgAgfReaderWriter();
    $agftext = $polystring ;
    $geometry = $wktReaderWriter->Read( $agftext);
    $geometryByteReader = $agfReaderWriter->Write($geometry);
    $geometryProperty = new MgGeometryProperty("Geometry",
$geometryByteReader);
    $propertyCollection->Add($geometryProperty);
    return $propertyCollection;
  }

The coordinate data in $polystring is formatted according to the grammar
described in 
http://mapguide.osgeo.org/files/mapguide/docs/2.0/da/dc0/group___agf_tex
t.htm

Best regards : Stefan

Hi Stefan, you can add and delete features using mapguide API, however
you
can't create non add fields to the SHPs.

	For sure you can modify SHP files with Mapguide API - I have
application
	 
	which adds and deletes features.
	I have not tried to create a SHP file, but I don't think it is
	impossible
