getFeature is the method to use to retreive a feature from a layer. It is a
layer method and
exists for both PHP and the SWIG-based bindings. It replaces the getShape
method which
I created with stupid parameter orderings that made it impossible to not pass a
tile index.
I see that it is missing from the PHP/MapScript docs but is present in the Swig
docs. I'll file
a ticket on that one... There's already a note at the bottom of the page but it
hasn't been
noticed.
