socket programming

#1 (**permalink**) 07-15-2003

Hi to all,

Is it possible to run php in the web running in a specified port without
installing apache in Linux?

Can anyone give a sample code for this? I'm searching this for a week but i
really can find one. Please help us.

Regards,

Mike

You could use inetd and the command line PHP binary. How to do it varies
between linuz distros, basically it allows you to assign a port number to
any program in the system and all the program has to do is send it's
output to the standard output (use echo in the case of PHP).

Do you mean to host websites with ONLY php and without webserver? Or do
you mean using PHP for something else then web, to make it listen for
incomming connections?

If the second, you might want to look here:

Maybe that helps.

Actually i want to create a server utility that can be administered through
web via a certain port, i'm afraid not to use php as an apache module
because the server might have an existing webserver installed, so i came out
into an idea to use php cgi/cli to run in a specified port and view it in
the web. It is somewhat similar to some existing utilities such as WEBMIN
which use perl cgi, but i really dont have a very good start since i dont
have enough examples for this. I've already opened opened port for this as
what David said but i cant see the output in the web.

He'res what i've did in my Redhat linux 6.x

inetd.conf:
samples stream tcp nowait.1000 root.root
/usr/local/mikecarel/samples samples

services:
samples 6886/tcp

samples:
#!/usr/local/bin/php -q
<?php
echo "Content-Type: text/html;charset=iso-8859-1";
echo "\n";
echo "<html>hello </html>";
?>

Am I in a right track? or is it possible with this? Do i missed something
here?

Thanks in advance.

This is pretty easy to do, but I should warn that PHP's socket support is still
labeled as experimental, though I have found it to be very stable, and I know
of no plans to change the API.

Quite a while ago now, I wrote a simple HTTP proxy in PHP that listens on port
4887 by default. It is a single script, so it is pretty easy to follow, and
you're welcome to check it out at http://protoscope.org/. It is probably a
better example than I could come up with here.

Hope that helps.

I am not very familiar with *nix administration at all so if anyone wants
to jump in and correct anything I have said wrong feel free.

Maybe try and have the command inetd is set to execute as
/usr/local/bin/php -q /usr/local/mikecarel/samples
instead of using a shebang line and having your PHP file executable and
see if that works?

I've downloaded your scripts and tried to test it on my server. Please
correct me if im doing it right.
I've opened services and port from the server to automatically run
protoscope only during acces in the given port (http:\\myserver.com:4887)
:

inetd.conf:
protoscope stream tcp nowait.1000 root.root
/usr/local/mikecarel/protoscope.php

services:
protoscope 4887/tcp

My question's are :
1. How could i access the rest of my php script residing in
/usr/local/mikecarel/ (http://myserver.com:4887/index.php) ?
2. If ever does the POST and GET method works properly on this?
3. Do I still need to install apache?

Hope I understand your application correctly.

Mike

I always just leave it running when I use it, but your method would probably
work as well.

Well, I meant this as a simple example of socket programming in PHP more than
anything. Since the application is an HTTP proxy, you would set up your browser
to use a proxy (specifying the host and port Protoscope is running on), and
then just type http://myserver.com/index.php in your browser's location bar
(assuming a Web server is running on myserver.com).

The method you mention makes the browser think it is contacting an HTTP server,
which is a bit different, so that wouldn't work.

> 2. If ever does the POST and GET method works properly on this?

Yes, but only as an HTTP proxy.

> 3. Do I still need to install apache?

If you want to connect to myserver.com and have it handle HTTP requests, then
you will need a Web server. If this is what you're looking for, you might be
interested in another PHP project called Nanoweb, which is a Web server written
in PHP. Because this task is much more complicated, the project is more
complicated as well, so it may not be the best learning example. You can learn
more about it here:

Hope that helps.
