You are trying to access the field values, correct?  The PHP MapScript
docs explains how to get to them:

--------8<--------
   int     numvalues (read-only)
   array   values    (read-only)

   The values array is an associative array with the attribute values
   for this shape.  It is set only on shapes obtained from 
   layer->getShape().
   The key to the values in the array is the attribute name, e.g. 
     $population = $shape->values["Population"];
-------->8--------

Note that you also have to make sure that you select the columns you're
interested in in your PostGIS select statement.  I'm not sure of the
details to do this, someone more experienced with PostGIS might be able
to help.
