[Asterisk-Dev] PHP vs C

[Kenneth Shaw]

PHP.

Use an Optimizer/Cacher like Turck MM Cache. This is essentially
compiling to byte code, and then running the PHP code.

PHP Has tons of benefits, similar to the benefits of using Java, Python
or similar. The great benefit of PHP, we've found is its easy
integration with web services, which can't be beat. Surprisingly, PHP
won't slow down your system that much in terms of call connect time.
This of course is dependent on how many simul. connections you're
expecting. 

What you can always do is do some kind of load balancing, if it becomes
an issue. In terms of cost, the extra hardware is more cost effective
than your developer's time would be. Estimate the amount of hours it
would take you to implement something in PHP/Java/Python/Whatever vs.
Standard C, and you'll probably realize that the "inefficiency" is a
good enough tradeoff. 

Currently, we're using nothing but PHP internally for our call agents.
They interact with a web based custom CRM solution, and the optimized
call routing is determined by our CRM libs, not by Asterisk. At peak, we
get maybe 2-3 connections per second, which handled across two 2.8 ghz
machines (one is DB/Web, the other is an Asterisk server), we are never
bogged down.

Developing a nice little LCR system for Asterisk would be nice, and we'd
use if it you cared to develop it, but there's no real necessity to
develop it.
