[PHPMapscript ]please add method mapObj->getAllGroupNames()

[thjack]

please add all methods of mapscript I use pmapper and like keep using it

[sdlime]

@geographika and @jmckenna, what do you think? This request is to fill a gap between PHPMapScript and Swig. It's a map-level method and wraps msGetAllGroupNames()... I don't see anything similar where we return an array of strings in Swig.

@sdlime from https://mapserver.org/mapscript/mapscript.html -

There are yet no mapscript methods that return arrays or sequences or accept array or sequence arguments.

I think the C# bindings do have one though - https://github.com/mapserver/mapserver/blob/branch-7-2/mapscript/csharp/csmodule.i#L125

We'd have to create typemaps for the other language bindings to support these (as I understand it, unless newer versions of SWIG support this automatically).

The typemap for Python from GDAL could probably be modified and used:

https://github.com/OSGeo/gdal/blob/master/gdal/swig/include/python/typemaps_python.i#L1026

I'm not sure about PHP - it looks as though the PHPMapScript could maybe be adjusted and added to SWIG as a typemap.

Any thoughts on use/support of Ruby, Java, TCL, and Perl bindings?

I was hoping for - newer versions of SWIG support this automatically... ;-) Seems like a pretty common need IMHO but it doesn't look to be the case based on the docs,

In terms of other languages, I would bet TCL see's almost no use - the others probably do. PHP-only could be considered as an initial target though. The other bindings don't know what they are missing...

@thjack : maybe you can use this workaround ?

function getAllGroupNames($mapObj)
{
    $aGroups = [];

    for ($i = 0; $i < $mapObj->numlayers; $i++) {
        $layerObj = $mapObj->getLayer($i);

        if (in_array($layerObj->group, $aGroups) === false) {
            $aGroups[] = $layerObj->group;
        }
    }

    return $aGroups;
}
```
