Thanks for the input.
You'll have to decide on static vs. dynamic based on your needs. In
either case, once the call is connected to your socket you've got
all sorts of control options. PHP has an ESL abstraction just like
the other languages so there shouldn't be any issue about PHP
lacking the ability to control calls.
But I'm having a hard time seeing how the ESL would duplicate this JS
functionality:
session.collectInput(onInputsml, "emptyobject", 7000);
How do I set the PHP callback routine, etc.?

Hi. Before I go to far down this path, I wonder if what I intend to
do is not a good practice.
I started using mod_xml_curl to use PHP on localhost to generate a
dialplan dynamically, based on the Caller-Destination-Number
variable that is posted. It prints out the XML that calls the
javascript that then controls the call. For example,
$response = <<< XML
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<document type="freeswitch/xml">
<section name="dialplan" description="example_curl_dialplan">
<context name="public">
<extension name="curl_test">
<condition field="destination_number" expression="^(\+1|1?)
(5844111)$">
<action application="javascript" data="demos/stest-examp-
st.js" />
</condition>
</extension>
</context>
</section>
</document>
XML;
Then I thought, that's silly to go back out to javascript to handle
the actions, playing files, using pocketsphinx, etc. I should just
stay in PHP, using esl.php to answer and handle the call.
Then I rethought, is that a good practice to take over the call
control from freeswitch at that point, while it is in the xml-curl
dialplan hunt?
Then I also thought, is it even possible to do some of the things I
need to do from the php esl, like the equivalent of this javascript:
session.collectInput(onInputsml, "emptyobject", 7000);

Just remember that you're dealing with two somewhat related but
still distinctly separate entities: generating a dialplan and
executing some sort of call control from the dialplan. You need some
sort of dialplan no matter what, so the issue there is whether you
need a dynamic one or not. If you're just going to drop calls to an
extension that opens an outbound socket to your call control program
then you may not need the dynamic dp generation that mod_xml_curl
gives you. You'll have to decide on static vs. dynamic based on your
needs. In either case, once the call is connected to your socket
you've got all sorts of control options. PHP has an ESL abstraction
just like the other languages so there shouldn't be any issue about
PHP lacking the ability to control calls.
I say start hacking away at it and see what happens. :) Definitely
join us in #freeswitch on irc.freenode.net if you want to discuss
this more in realtime.
