[mapserver-users] Swig mapscript troubles

[Jeff McKenna]

Hi Eric!

First sorry for my poorly formatted response, in fact your email never 
made it to my inbox, as the email server for this list is hosted on a 
machine that was recently tagged on a spam 'blacklist' (see 
https://trac.osgeo.org/osgeo/ticket/2475), so I'm piecing together a 
response to you manually ha.

Regarding upgrading to MapScript SWIG, the MapServer migration guide 
actually lists 2 very important points regarding PHP that must now 
always be followed (see 
https://mapserver.org/MIGRATION_GUIDE.html#mapserver-7-2-to-7-4-migration). 


    1) all of your PHP scripts (that leverage MapServer objects and 
functions) must now always first include the generated 'mapscript.php' 
file containing MapServer constants:

        // required SWIG include (contains MapServer constants for PHP7)
        include("C:/ms4w/apps/phpmapscriptng-swig/include/mapscript.php");

    2) take note of the change in how to declare your new objects with 
the "new ..Obj" syntax :

        // open map
        $oMap = new mapObj("C:/ms4w/apps/phpmapscriptng-swig/


Regarding the required file 'mapscript.php', if you are compiling 
MapServer yourself, it will be generated in your build folder alongside 
the generated 'php_mapscriptng.so' (such as in

     /mapserver-master/build/mapscript/phpng/

By odd chance, earlier today I added a working example for how to create 
a new point object (with an inline feature) through PHP mapscript SWIG: 
https://ms4w.com/trac/wiki/SWIGMapScriptNewLayer

The important parts of the example PHP script are:

   <?php

   // define variables
   define( "MAPFILE", "C:/ms4w/apps/phpmapscriptng-swig/sample.map" );

   // required SWIG include (contains constants for PHP7)
   include("C:/ms4w/apps/phpmapscriptng-swig/include/mapscript.php");

   // open map
   $oMap = new mapObj(MAPFILE);

   //******
   // create new point layerObj
   //******
   $oPointLayer = new layerObj($oMap);
   ...

   // draw map
   $oImage = $oMap->draw();

   ?>

Hope that makes a little sense ha!
