[Mapserver-users] premature end of script headers (php)

[Charlton Purvis]

Thanks for the map.h MS_MAXCLASSES pointer, folks, and thanks for the
user thread pointers, too.  I don't know why I have such rotten luck
finding information in the threads, but I do.

Anyway, I didn't see any clear answers to what a reasonable number of
classes would be, though.  Should I look at it w/ this attitude:  (a)
I've got 100 classes, so I need to up MapServer's anti and simply get
the job done; OR (b) I need to revisit what I'm trying to render because
100 classes is unreasonable.

Thanks,

Charlton

If you are able to recompile MapServer you can edit map.h and increase 
MS_MAXCLASSES (default is 50).  As long as you compile with a value 
greater than the max number of classes you need to use, you won't 
receive the error you described.  There were some posts about this 
recently, and about how many classes are reasonable:
