Thanks Andy, I think we both mean well.

It is true that at the moment I can't confirm yet all these sites with
their "benchmarks" stating such a big performance improvement from PHP 7.
I also can't confirm how this will impact map drawing speeds through
PHPMapScript.  I guess the point of these alphas and my work is to push
this along, help PHP 7 + MapServer community along.  This was a big hurdle
for me (PHP 7 required the latest Visual Studio compiler, and if you have
ever tried to compile on Windows, that means the whole MapServer and GDAL
stack, and don't forget I also compile the whole Apache+modules and
PHP+extensions stack on Windows, which is quite a massive effort - even the
PHP dev team is aware of my MS4W work now on Windows).

This was a big first step, and I agree it could be taken as sort of a tease
("well ok, but where is PHPMapScript?"), ha, of course, good point.  I hope
this helps advance things, help things move along, as (when I first
mentioned MapServer + PHP 7 back in December last year) I really feel that
this is very important for the MapServer community, but spoken of very
little.

I did get a response back from the Mapbender dev team already, and I'm sure
other dev teams will be working towards PHP 7 and keeping this momentum
going.
