Hi Jens,
Thank-you for the complements.
In the MS4W 5.0-beta2 announcement I mentioned that I had created a
Migration Guide on the wiki, that I recommend that you take the time to
go through in detail: https://ms4w.com/trac/wiki/MigrationGuide5.x
There you will find a section on SWIG MapScript, that also includes 4
working PHP scripts for MS4W 5.0-beta2, with a note about changes to
setting metadata using the new hashTableObj way. I also now added a
working example for *getting* a metadata value (see the last 'echo'
command below), such as:
<?php
//set metadata using the new 'metadata' hashTableObj keys and value
directly
$oWMSLayer->metadata->set("wms_name", "popplace");
$oWMSLayer->metadata->set("wms_title", "Cities");
$oWMSLayer->metadata->set("wms_srs", "EPSG:3978");
$oWMSLayer->metadata->set("wms_server_version", "1.1.1");
$oWMSLayer->metadata->set("wms_format", "image/png");
//get metadata using the new 'metadata' hashTableObj keys directly
echo $oWMSLayer->metadata->get("wms_title");
?>
As always, I kindly ask you that you add to that wiki page, by adding
your examples and notes so others can learn from your tips. (it's a wiki
on purpose, to hopefully get everyone editing it and adding migration
examples, as you modify your mapfiles for MS4W 5.0).
I hope this brings you out of the 'darkness', ha, and that you have a
nice, quiet weekend.
Thank-you for using MS4W.

Dear list and especially dear Jeff,
thank you for creating and supporting MS4W. Although MS4W doesn't
completely fit our demand, it is marvelous how easy it is to set it up. :)
I wanted to have a look at the new Mapserver/PHP-Combo and tried to make
one of our projects work with it. After fixing some deprecations here
and there, I encountered some difficulties with MapScript I was not able
to circumvent. :(
When switching to PHP7 I had to include the php_mapscript.dll and (I
guess that was the SWIG-Version then?!) a mapscript.php.
Sven brought this up in a message in december. This time there is no
more mapscript.php and if I include the old one it raises an error, that
the classes are already there, which is plausible. But if I don't it
seems that there is something (i.e. some functions and attributes [e.g.
mapObject->numLayers]) missing. But in general MapScript is loaded and
does work.
Since I wasn't sure if it is a problem with my software setup, I used a
plain version of MS4W (5beta2) on another machine to reproduce it. Took
about 5 Minutes to unzip and about 5 seconds to make it work... Wow!
An example to reproduce my problem is to add the following lines to
quickmap.php at line 20 and comment the rest of the file.
$layer = $oMap->getLayer(0);
echo "Layer: ".$layer->name."<br>";
print_r(get_object_vars($layer->metadata));
echo $layer->metadata->wms_title."<br>";
$layer->getMetaData("wms_title");
Getting the layer and printing the name ("ocean") does work. The
metadata actually is a hashTableObj, but get_object_vars gives an empty
array. Directly accessing the attribute just returns NULL. Calling
getMetaData() like we used to leads to the "Fatal error: Uncaught Error:
Call to undefined method layerObj::getMetaData()" although is it
mentioned in both the SWIG and PHP MapScript API.
Don't know if these a bugs or features. =) Could it be that there have
been some changes in the code that are not yet documented? Maybe one of
you can bring some light into the darkness?!
Kind regards,
Jens
