Class Expressions & Class Items

[Thorsten Fischer]

Ladies & gentlemen,

I am using php MapScript to display data from shapefiles. The .dbf
data files have been imported into an Oracle database for
performance and maintenance reasons.

I want to 'highlight' one or more shapes in a layer by filling
them with a different color. Using a map file, I would do
the following:

[ BLA BLA LAYER DEFINITION ]
CLASSITEM "name"
CLASS
  EXPRESSION /<whatever>/
  COLOR <a lighter color>
END
CLASS
  EXPRESSION /./
  COLOR <default color>
END
[ REST OF BLA BLA ]

Coding in php MapScript, I would now get the first class with
getClass (), set a new expression, redraw the map, and that's it.

Unfortunately, the CLASSITEM stuff is retrieved from the .dbf
file of course, which does not exist for me anymore.

Any suggestions?
