[MS4W-Users] ms4w 4.0.0 PHP-Mapscript Test

[Jeff McKenna]

Hi Ludwig,

As the instructions that I pasted here in my previous message stated, 
PHPmapscript in MS4W verson 4 and onward requires the SWIG MapScript 
API.  This means that the mapscript function & method names may have 
changed, if you have old code that leverages the PHP MapScript API 
instead.   Therefore the SWIG MapScript API Reference document is now 
your guide to follow for all of your function & method names 
(https://mapserver.org/mapscript/mapscript.html#swig-mapscript-api-reference).

For example:

  - the old PHPmapscript API function ms_ResetErrorList() is now named 
msResetErrorList() (according to 
https://mapserver.org/mapscript/mapscript.html#mapscript-functions )

- the old PHPmapscript API constructor way for declaring new objects, 
such as ms_newLayerObj(), has changed to the syntax: new xxxObj (as you 
can see in the layerObj methods at 
https://mapserver.org/mapscript/mapscript.html#layerobj-methods )

Here is a working example:

   // create new layer object
   $oLayer = new layerObj($oMap);
   $oLayer->set("name", "cities");
   $oLayer->set("type", MS_LAYER_RASTER);
   $oLayer->set("status", MS_ON);
   $oLayer->setConnectionType(MS_WMS, NULL);
   $oLayer->set("CONNECTION", 
"https://demo.gatewaygeomatics.com/cgi-bin/wms_gateway?");
   $oLayer->setMetaData("wms_name", "popplace");
   $oLayer->setMetaData("wms_srs", "EPSG:3978");
   $oLayer->setMetaData("wms_server_version", "1.1.1");
   $oLayer->setMetaData("wms_format", "image/png");
   $oLayer->SetProjection("init=EPSG:3978");

*note that there is a missing alias for the set() method, as you can see 
around line#2118 in SWIG's generated mapscript.php file, so you can 
change "function __set" on that line to "function set"

Hope this helps.

Thanks again for your interest in MS4W.

-jeff
