1623	[PHP] Add Geos function : Contains	assefa	jmckenna@dmsolutions.ca	"{{{
Add geos function contains  (see also Bug 1327). Here is an e-mail from Steve 
explaining how it works :

 For grins I added the conains operator to the geos wrapper and to Swig-based
mapscript. That support is in CVS head (not 4.8, too late for that, sorry).
I hesitate to touch the PHP wrapper though. You'll have to convince one of
the other developers to make that change (or have them ok me doing it).

Anyway in a language like Perl you can do:

shape1 = mapscript::shapeObj::fromWKT('POLYGON((0.0 0.0, 0.0 2.0, 2.0 2.0,
2.0 0.0, 0.0 0.0))') or die(""Shape 1: "". mapscript::msGetErrorString(""\n"")
.""\n"");
$shape2 = mapscript::shapeObj::fromWKT('POLYGON((0.5 0.5,0.5 1.5,1.5 1.5,1.5
0.5,0.5 0.5))') or die(""Shape 2:"". mapscript::msGetErrorString(""\n"") .""\n"");

print $shape1->contains($shape2) .""\n"";
print $shape2->contains($shape1) .""\n"";
print $shape2->contains($shape2) .""\n"";

Which outputs:

1
0
1

as expected. This is only exposing the operator. Nothing is itegrated into
the MapServer query functions. However, in MapScript you could:

1) use the bounds of shape 1 to do a rect-based query and then
2) loop through the result set doing contains

I'm not going to do a full implementation of GEOS until I convert the cpp
interface to c (sometime soon). However, it seems like contains might be
interesting to folks in the meantime so...
