Hi Yioit,
I believe AMFPHP was originally created to work with remoting in
Flash (not Flex). The XML handling abilities of Flash are not in the
same league as Flex, so XML was a huge pain. AMFPHP definitely makes
a big difference for Flash Development.
Since Flex is so much better with XML, the benefits may not be so
obvious depending on the specifics of your project.
I agree with you that there can be a lot of overhead in creating
client-server interfaces and working out the best way to serialise
data for transfer etc. As for your comment about having to write
classes in both PHP and ActionScript: I don't see that there is any
escaping this. Unless your application is trivially simple, then you
will surely want to create domain model objects on the server to
encapsulate logic and the database access. Same goes for the Flex side.
As for the most development time efficient method for architecting
the service interface, I'm still trying to figure that out. There are
several options for both XML and AMF in PHP and also in other
languages. WebORB for Ruby on Rails is another alternative that can
potentially save time once you get over the Rails learning curve and
learn how to install everything properly (which is a significant
investment).
You are correct that AMF serialised data is quicker to transfer and
marshal than the equivalent XML, but this probably only becomes an
issue when your dealing with quite large result sets.
With regard to your generalised database query over HTTP class: I'm
all for this type of time saving solution, but I think you need to
address a couple of issues to make it more widely useful. Namely, the
security concern of having a service that allows clients to
effectively design their own SQL queries to be executed on your
server, and secondly the fact that this approach seems to bypass the
server side domain logic.
Cheers,
Lach

hi,
i've been developing web RIA's using PHP&mysql support for data for
about 3-4 months. writing diffrent php files for every fetch type
was sucking so i've starting developing a new class communicating
with my own php file to fetch data. my class is so pre now but you
may find some info about it athttp://yboyar.blogspot.com/2006/12/
easyreq-http-service-class-which-makes.html .
anyway; my question is sth diffrent. also i read a lot about
AMFPHP , i still could not understand where it helps me reduce time
to build applications since i write every class in php & actionscript.
i've downloaded AMFPHP but although i did the database setup , it
still gives error.
So, please can someone clearly explain me how AMFPHP helps time
reduction WHILE developing the application ? (or does it ?)
as much as i understood, it help reducing transferred data size in
the running time. Am I right in this point ?
thanks a lot, by the way; what do you think about the tool i
develop; does it seem helpful or useless ?
