[Mapserver-users] A QUERY only mapfile, PHP/Mapscript, get not results

[woodbri at swoodbridge.com]

Hi all,

My brain must have gone on vacation or something, because I have what 
I thought should be a trivial example to put together and I can not 
seem to get it to work!

Built a simple php script to do a query of a query only mapfile and 
print the results. I have included below the results, query.map, 
t2.php

So, does anyone have any ideas on what stupid thing I have 
overlooked. Oh, the world_countries_shp file is good and in units DD.
I have tried this with 12 different layers all with the same results. 
I just stripped that down to this simple example. And I have tried it 
on php-4.3.1 and MS-3.7_dev with the same results.
