Hi,
I have some basic questions on running php (5.2.x series on Linux
2.6) as a standalone daemon using posix methods (fork() etc..):
#!/usr/bin/php
<?php
require_once ('someclass.php');
// do some initializations
.
// main 'forever' loop - the '$shutdown' will
// be set to true via a signal handler
while(!$shutdown)
{
$a = new SomeClass();
$a->doSomething()
}
// shutdown logic.
The 'someclass.php' in turn will include other files (via require_once).
The above file will be executed directly from the shell. The main loop
could be listening to new requests via sockets etc..
Few questions:
1) Does opcode cache really matter in such cli-based daemons? As
'SomeClass' is instantiated at every loop, I am assuming it is only
compiled once as it has already been 'seen'.
I am not very clear on how apc (or eaccelerator) works in such cases.
2) What about garbage collection? In a standard apache-mod-php setup,
we rely on the end of a request-cycle to free up resources - close
file descriptiors, free up memory etc..
I am assuming in the aforesaid standalone daemon case, we would
have to do this manually? In the loop above, would it be better to
'unset($a)' explicitly at the end of it before
it goes to the next iteration?
Note: I have written pre-forker deamons in php directly and
successfully deployed them in the past, but never looked at in depth
to understand all the nuances. Anecdotally, I have
done 'unset()' at some critical places were large arrays were used,
and I think it helped. AFAIK, unlike Java, there is no 'garbage
collector' thread that does all the magic?
Thanks,
Ravi

You do this all the time without realizing it!
echo "Hello, " . $name;
$rect->setTopLeft(new Point(5 * 3, 2 / 3));
These expressions are eventually assigned to function parameters or passed
to the PHP engine in the case of echo, but there are no assignment operators
present. And all of the control structures--if, while, for, etc.--take
expressions. Expressions are all around us. You can feel them when you go to
work . . . when you go to church . . . when you pay your taxes. No wait,
that's the Matrix.

We use part of Zend MVC (the dispatcher, controllers, and view scripts) here
and a lot of the other facilities such as the autoloader, config, etc. and
are very happy so far. As long as you design your application with an eye
toward portability, you won't be tied to ZF. For example, put all of your
business logic in model classes instead of the controllers themselves. That
way if you ever need to move to a new presentation layer or use the business
logic outside it (e.g. in SOAP or RPC messages), you'll be ready.

Thanks for the info everyone, this is pretty much what I was expecting to
hear about it. I think I'll probably stick to using it as a toolkit.

I'm looking at someone's code to learn and I'm relatively new to
programming. In the code I see commands like:
$code->do_command();
I'm not really sure what that means. How would that look in procedural
style programming? do_command($code); or something else?
--- End Message ---
--- Begin Message ---
Adam-
That is a function call. In Java:
class Code
{
public static void function do_command(){ }
}
Code.do_command();

Did you mean to say "That is a method call."?

Bob-
Yes, yes I did.
And note that my Java code is incorrect, that should simply be public static
void, no function.
This is what I get for taking a week to code everything in Node.js.

It's object oriented code. $code is an instance of class, and do_command() is a
method if that class. I'd advise reading up on oop php.

Not just Java, but does I've seen this in several languages.
Javascript is one. But realize that Java is to Javascript as Ham is
to Hamster. In other words, the two aren't related.

regarding Node.js after a week of working with it?

Adam-
It is unique. I'm writing code that really can't be done any other way. How it
handles events, sockets, etc is exceptional. The best part is everything now is
JavaScript. The server (Node.js) is written in JavaScript. MongoDB is
JavaScript. The frontend used to manage the WebSocket is entirely JavaScript.
I have essentially replaced J2EE as the backend with Node and I couldn't be
happier.
Of course standard JavaScript woes apply. Debugging is a royal pain in the ass.
Your code can and will suddenly fail due to odd strange errors. There are
stability concerns with Node, it is version 0.2 after all.
It won't replace PHP or Java as an enterprise level solution, but it does fill
in the gaps very nicely.
Regards,
-Josh

Thanks for the insights, Josh.
I've been intrigued by Node.js and it's architectural implications, and your
feedback helps as I evaluate potential projects/experiments going forward.
Excellent point about the debugging relative to other environments. Palm's
inclusion of Node.js in webOS 2.0 does help provide more confidence in the
code-base, even if it is relatively early in the development cycle, so I
guess I'll have to start tinkering soon :)
Thanks again,
Adam

Ok, here it goes...
I am building an app, that requires a web interface. I am using PHP
becuase I am familiar with it. Most of the app's i've been looking at,
use Python, Cherry.py and stuff, but what I was wondering, is is there a
way to create a php CLI app, that creates it's own "web server" even if
apache is installed.
i want to be able to run it on like port 8880 or something... just
looking out there fro something...

OH, i forgot to mention, if it ran on windows or linux, and required no

I had written one about two years ago for a project, but the code
belongs to the client company, so it won't make it to open source.
However, not only can it be done, but there's even some in existence.
Check this one out:

I've never used it myself, but it may be worth a shot for you.

Ok, here it goes...
I am building an app, that requires a web interface. I am using PHP
becuase I am familiar with it. Most of the app's i've been looking at,
use Python, Cherry.py and stuff, but what I was wondering, is is there a
way to create a php CLI app, that creates it's own "web server" even if
apache is installed.
i want to be able to run it on like port 8880 or something... just

I use this as a mini web server on my XP workstation just for testing
little things. I have no idea how well it will perform in real world
use nor have I tried it on any *nix setup.
Just my experiences...
