Re: [UMN_MAPSERVER-USERS] php help

Steve,
I interpreted your outline as best I could into PHP code, but my code
is dying at the inner loop.  I don't think I am calling the individual
lines from the shape correctly....

Here is my code:
        $new_shape = ms_newShapeObj(MS_SHAPE_LINE);
         foreach ($oShapeObjectList as $Shape)
         {
               foreach ($Shape as $line) {
                 $new_shape->add($line);
               }
         }

         $buffered_shape = $new_shape->buffer($dfTolerance);
         $shapefile = ms_newShapeObj(MS_SHAPE_POLYGON);
         $shapefile->add(buffered_shape);

Any Ideas?
Sincerely,
Bryon

You can only add lines to a shape so the psuedo code would look like (I think 
you're missing the inner loop):

new_shape = new shapeObj(MS_SHAPE_LINE)
for each shape in the list {
  for each line in the shape {
    new_shape->add(line)
  }
}

buffered_shape = new_shape->buffer(width)

shapefile = new shapefileObj()
shapefile->add(buffered_shape)

I am retrieving a list of shapes from a line shapefile file using the
following code:

for($x=0;$x<count($oShapeList);$x++)
{
   $oSelectedShape = $oRelationLayer->getshape(-1, $oShapeList[$x]);
   array_push($oShapeObjectList,$oSelectedShape);
}

I want to merge this list of shapes into one shape (i.e. one line).  I
thought I could do it using the following code but it returns a "Fatal
error: Object has an invalid _handle_ property":

$oLine = ms_newShapeObj(MS_SHAPE_LINE);
For($x=0; $x<count($oShapeObjectList);$x++)
{
   $oLine->add($oShapeObjectList[$x]);
}

The goal here is to create one line, then use the GEOS - buffer(width) to
create a polygon object that I can save to a new shapefile.

Does anybody have any ideas? OR CODE!!!

Sincerely,

Bryon
