getFilter() & setFilter() with PHP Mapscript

[Armin Burger]

Hi everybody

in PHP Mapscript the 'getFilter()' request applied on PostGIS layers 
having a filter defined in the map file returns a string already put 
into double quotes. This seems to be so since Mapserver 4.6. Since 
Mapserver 4.10 also the reverse 'setFilter()' seems to work only 
correctly for PostGIS layers if the filter is defined as string with 
literal double quotes around.

So that's not working:

   $mylayer->setFilter("field_1 = 2 AND field_2 = 2004");

That's working:

   $mylayer->setFilter('"field_1 = 2 AND field_2 = 2004"');

I wonder if this is an intended 'feature'.
