For the above map Script is working fine. But while I am querying I did not getting the results. How can query the map using PHP at point and selected rectangle area.
Is any one can send the script for this.
In this project i am not using applets. Just Map querying on 7 layers using php.

You will have to provide more details on what you are trying to do
exactly if you want anyone to be able to help.
If by "query the contents of .tab layers" you mean clicking on a map
image and selecting features from a TAB layer then this works the same
way for shapefiles and for .tab files. The only difference is that you
need MapServer with OGR support, and you define an OGR CONNECTION in
your LAYER. For more details on using OGR CONNECTIONS, see the OGR
