[Mapserver-users] trying to start - mapserver and php Mapscript

Leonardo, 

A couple of things that I see with a quick scan.  

1.  IMAGEURL  
You have        IMAGEURL "c:/temp/", this looks like a path to me.  You want to use a URL.  e.g.     
IMAGEURL "/tmp/" where /tmp/ is a directory in your Web root.

2.  Because you are only displaying one data layer, comment out your projection info until you get your application working.  There is no need for projection info until you are displaying multiple layers of different projections.

3.  Change the STATUS of your layer 'quadras' to DEFAULT.

David.

Hello, I´m Leonardo Vilela, from Brazil and need too help.

 I´m trying to disponibilize a map that I have in shapefile in web with mapserver.
I´m studying the mapserver's features and reading the documentation, but it´s being very dificcult and i think that i need help.
There are some questions that I need to understand, and I expect that someone can help me:

1 - I´ve downoloaded a dll file called php_mapscript_42.dll and put it in php's extension dir, the demos of mapserver worked correct, but others examples that i study uses a archive called php_mapscript.so, what is php_mapscript.so? I need this to run In a apache/php server on windows?

2 - I have a shapefile that contains all squares of a town, I want try to view it with mapserver.
I do a .map file with the projections of the place that i found in http://mapserver.gis.umn.edu/doc40/proj.html , and create a simple file in php to generate a image.
The image was blank. There wasn´t error messages, but there wasn't any polygons...

I´m sending a copy that a file to yours, and i expect that someone can help me.
Thank´s a lot:
