PHP MapScript queries

[Daniel Morissette]

Thorsten,

I'm not sure if this is related to your problem or not, but you need to
have a QUERYITEM and a QUERY object in your layer definition for your
layer to be queryable.

However, I'm still concerned by the seg. fault and would like to be able
to track it... if you're using a recent version of MapServer (less than
a month old) and still get the seg. fault, then perhaps you could zip
your PHP script and data and send it to me and I'll see if I can
reproduce the crash.
