LIX. IRC Gateway Functions


With IRCG you can rapidly stream XML data to thousands of concurrently connected users. This can be used to build powerful, extensible interactive platforms such as online games and webchats. IRCG also features support for a non-streaming mode where a helper application reformats incoming data and supplies static file snippets in special formats such as cHTML (i-mode) or WML (WAP). These static files are then delivered by the high-performance web server.

Up to v4, IRCG runs under these platforms:

  • AIX

  • FreeBSD

  • HP-UX

  • Irix

  • Linux

  • Solaris

  • Tru64

  • Windows

注: 本扩展已被移动到 PECL 库中且自以下版本起不再被绑定到 PHP 中:5.1.0.


Detailed installation instructions can be found at We urge you to use the provided installation script.

It is not recommended, but you can try enable IRCG support yourself. Provide the path to the ircg-config script, --with-ircg-config=path/to/irc-config and in addition add --with-ircg to your configure line.

I have posted the last BSD-Licensed version of ircg at
2005/08/09/ircg-27-last-bsd-licensed-version/ (link broken into two lines)

I haven't tried the IRC packages in PEAR, but I'd suspect that ircg is much faster and better in handling high amounts of connections, since these things are rather tricky to do in php.

In fact, this IRCG is shareware (which limit to 10 connections at one time only) and useless!
The real solution is the Net_SmartIRC PEAR Package
The Net_SmartIRC package provide all the function that you need with IRC and it is possible for you to send a raw command to the IRC server. I highly recommand you to use Net_SmartIRC instead of IRCG!

Yes, the newer versions are shareware, but the older version is not so I don't see why this should be removed. And it is still freely available on his website here:

But as the URL might indicate to you, it's Win32 servers only.

ircg 3 and 4 are shareware, but ircg 2 was bsd-licenced. I still have that version (sasha schumann pulled it from his website - i wonder why). Send me an email if you want it.

watch out, ircg is shareware as it seems.
Quoting from :
The IRCG 4 Free Trial does not allow more than 10 concurrent connections
Answer: The IRCG 4 Free Trial is limited to 10 concurrent connections. You can buy an unlimited license by contacting us here.

Poor job, documentation team. Do you like promoting shareware in your manual just because its from a core developer?

If you just need an IRC client/bot in PHP without this IRCG extension, you want to look at the PEAR::SmartIRC class. Here the direct link to this class:

This is an example to show how to connect to a IRC server, how to join a channel, send and receive messages.


/* change it to your own nickname                                              */
$nickname              = "myOwnNick";
/* choice your irc server                                                      */
$server                = "";
/* change to your channel                                                      */
$channel                = "#linux";
/* do not change it if you do not know what means :-)                          */
$port                  = "6667";

/* as ircg cannot resolve hosts, we use PHP internal function to get the IP    */
$ip                    = gethostbyname($server);

/* connection                                                                  */
$id                    = ircg_pconnect($nickname,$ip,$port);

/* checking if  connected                                                      */
if (!ircg_is_conn_alive($id))
"Cannot connect<br>";

/* joining a channel                                                            */
if (!ircg_join($id,$channel))
"Cannot join to $chanell<br>";

/* getting messages - you must have this in your php file                      */

/* send messages to your channel and you                                        */
ircg_msg($id,$channel,"Hello $channel!!");
ircg_msg($id,$nickname,"This message goes to me!!!");

You may face problems with php 4.20 configure script when using "--with-ircg-config" without providing any path to script file. When it tries to configure ircg it just starts printing --ldflags continuously.

checking for IRCG support... yes

So always provide path to ircg-config file as in --with-ircg-config=/user/local/bin/ircg-config
