Open a shapefile and read its shapes' attributes

[Pietro Giannini]

Hi Knight,

the php_mapscript ShapefileObj object do not read the values of the shapes
(?!?), it seems.
You must to read the values in the .dbf file; the dbf entries are in the
same order of the shapes.
Your php need the "php_dbase" extension.

the code:

<?php

   $Path = '\ms4w\apps\map\routes.shp';
   //  the dbf file identifier:
   $LineDBFFile = dbase_open("\ms4w\apps\map\routes.dbf",0);
   $LineFile = ms_newShapefileObj($Path,-1);
   $numshapes = $LineFile->numshapes;
   if($numshapes > 0)
   {
      for($i = 0; $i < $numshapes; $i++)
      {
         $Line = $LineFile->getShape($i);
         $aLineValues = dbase_get_record_with_names($LineDBFFile,$i);
         $RouteName  = $aLineValues["RouteName"];
         printf($RouteName );
         $Line->free();
      }
    }
    $LineFile->free();
    dbase_close($LineDBFFile);

?>

ciao
