[PHP] Shared Memory with Yast-installed mod_php4 from SuSE.
Hi, i try to use the shared memory functions on a SuSE Linux 7.0 server with Apache and mod_php4 out of the box installed with yast. For shmop i need to configure PHP with --enable-shmop with isn't enabled in this installation. I know how to enable this when compiling and installing the source of mod_php4, what is to difficult for me, i think. But how to enable it in the SuSE-RPM-Distribution? I found a mod_php4.spec in /usr/src/packages/SPECS in wich the configuration options are, butr i don't know how to use it to install this RPM with my own configuration. Can anyone help me?

[PHP] httpd-prozess doesn't get killed
Hi,
i code a streaming chat in PHP4. Everithing works fine, it is very fast due
to use of shared memory. But i have this problem: Every time i start the
script a new httpd-process is started (Apache 1.3.12). So far so good. But
the process doesn't get killed when aborting or reloading the script. So if
you reload the stream an few times you have a task list full of Apaches.
How can i kill the old, unused process when i reload the page?
I tried if($connection_aborted()) { exit; }, but it exits the first time.
Thanks,

[PHP] Response 304
Hi,
i want a script to produce a "HTTP/1.0 304 Not Modified" or "Status 304 Not
Modified". Normally when i send this header after GET data to a script, it
should not be loaded. (in this case: an input-frame of a chat should not be
reloaded after submitting the data.). I heard the script should only send
the header without message body. so i tried:
header ("HTTP/1.0 304 Not Modified");
exit;
But this don't work. The Script is loaded and, of course, an empty page.
How can i do this???
Thank you.

[PHP] socket_write eats data
Hi,
I am deveoping a chatserver in IRC-style in PHP. For communication it uses
socket-multiplexing aka socket_select. So long so good, works perfectly.
The problem is, than when i make several socket_write's to the same client
without waiting about 0.1sec after each write, the written data gets lost
somewhere. socket_write does NOT throw any error, the data seams just
sended, but the clients never receives it.
Small example of the used code:
-
var $clients // array of 'client'-objects, each object has it's own
socket-descriptor in the object-variable $socket
function write_to_clients ($text) {
for ($i = 0; $i count ($this-clients); $i++) {
socket_write ($this-clients[$i]-socket, $text);
}
// usleep (1); if this is uncommented, all write are received by all
clients
}
for ($i = 0; $i 10; $i++) {
$this-write_to_clients (test .$i);
}
-
Okay, this doesn't check the client-sockets for readiness to write, but even
if I check (via socket_select), ALL clients are ready to write and writes
get lost too. It can't be the network-connection, because the tests run with
standalone PHP-clients on the same machine.
Is there any possibility to make fast writes without waiting after each
write? The wait limits the server to max. 10 writes per second, wich isn't
really enaugh for a good chatserver.
Thanks for your help!

Re: [PHP] socket_write eats data - solved
Hi,
i've checked a hundred things before posting this question, but i forgot the
most important thing, the buffer.
The 'eaten' writes were buffered by the network-kernel and sent as bunch of
data. If too much data for the buffer is sent, the write is broken up and
completed in the next bunch-of-data.
My receive-script hasn't diplayed the raw output, but an unserialized array,

No, it's TCP and a very uncomplicated protocol, everything is sent in clear
text. Major problem is the socket-multicasting to keep track of all clients
simultanly.

Re: [PHP] socket_write eats data - solved
IMAP? We were talking about IRC, the Internet Relay Chat.
In detail, my problems doesn't even refer to IRC directly, as i am
developing a server for a html-based webchat, but the server-structure and
the messages are nearly the same.
Once you realize the basics of socket-multicasting, it is no problem to
maintain hundreds of simultanous TCP-connects via arrays of sockets, also
called descriptor-sets. PHP seems to directly use the underlying C-
libraries, so everything you can imagine is possible.
Anyway, the major drawback of PHP in this case is speed. Currently i can
send about seven messages per second (one send means socket-connect of a
input client, some simple processing of the message and sending it to all
connected listening clients) with a dozen listening clients, but only about
three messages per second with two hundred listening clients. As C-written
IRC-servers sometimes have thousands of connected clients, i can only
imagine that it is PHP which has some not so efficent array- or
resource-handling.

Wouldn't this multiple connections be a problem for php? IMHO one of the
main draw backs of the PHP IMAP library is the fact that you have to
open and close and imap connection for each page. That issue is
multiplied ten fold in this scenario isn't it?

Is IRC UDP?

Hi,
i've checked a hundred things before posting this question, but i
forgot
the
most important thing, the buffer.
The 'eaten' writes were buffered by the network-kernel and sent as
bunch
of
data. If too much data for the buffer is sent, the write is broken up
and
completed in the next bunch-of-data.
My receive-script hasn't diplayed the raw output, but an unserialized
array,
fetched out of the received string.
Maybe this will will help someone in future.

Subject: [PHP] socket_write eats data
Hi,
I am deveoping a chatserver in IRC-style in PHP. For communication it
uses
socket-multiplexing aka socket_select. So long so good, works
perfectly.
The problem is, than when i make several socket_write's to the same
client
without waiting about 0.1sec after each write, the written data gets
lost
somewhere. socket_write does NOT throw any error, the data seams just
sended, but the clients never receives it.
Small example of the used code:
-
var $clients // array of 'client'-objects, each object has it's own
socket-descriptor in the object-variable $socket
function write_to_clients ($text) {
for ($i = 0; $i count ($this-clients); $i++) {
socket_write ($this-clients[$i]-socket, $text);
}
// usleep (1); if this is uncommented, all write are received by
all
clients
}
for ($i = 0; $i 10; $i++) {
$this-write_to_clients (test .$i);
}
-
Okay, this doesn't check the client-sockets for readiness to write,
but
even
if I check (via socket_select), ALL clients are ready to write and
writes
get lost too. It can't be the network-connection, because the tests
run
with
standalone PHP-clients on the same machine.
Is there any possibility to make fast writes without waiting after
each
write? The wait limits the server to max. 10 writes per second, wich
isn't
really enaugh for a good chatserver.
Thanks for your help!

[PHP] Close Connection to Browser
Hi, is it possible to close the connection to the client/browser without calling exit? I have an input-script for a chat-system, wich gives a Status 204 No Content to the client after submit, wich works great. The problem is, that sometimes the script needs some time to finish after sending the 204 and keeps the connection over this time, wich couses Internet Explorer and sometimes even Mozilla to crash if too much connections to the script are active.

Re: [PHP] Chat with php
I've thought about adding the text on the top, but never found a good way to
make that (not with plain HTML, it would require a java-applet to display
the stream).
Scrolling is quite simple, i use this:
head
SCRIPT language=JavaScript
!--
doscroll = true;
function Scroller() {
if (doscroll != false) {
window.scrollBy(0,15);
}
window.setTimeout(Scroller(),15)
}
Scroller();
parent.atok = 'CCOFs';
function atok(p1) {
parent.atok = p1;
}
//--
/SCRIPT
/head
body onFocus=doscroll=false onBlur=doscroll=true
onMouseOver=doscroll=false onMouseOut=doscroll=true
...
It scrolls down whenever the mouse is outside the frame with the stream.
Cya,

Hey cool,
That's working. The only problem I have now is that I want the most recent
text
at the top. But that script adds it on the bottom. Any way to change that?
At
least a way to always scroll automatically to the bottom?

[PHP] fork and childs

[PHP] socket_select() hangs sometimes; Bug?
Hi folks,
I am battling around with socket_select() for some months now and still have
an unsolved problem with random hanging.
PHP: 4.3.4 with -sockets, -sigchild, -pcntl and some other things
OS: FreeBSD 5.0 (same problem with 4.8 and 5.1)
In simple words, I have a server-daemon (runs with PHP4.3.4 now) wich uses
socket_select() for accepting new connections and dealing with existing
ones. It is an IRC-like chatserver talking with PHP-script running on a
webserver on _the same_ machine, same IP, long connects for output, short
connects for input. For debugging I use normal TCP-sockets, not
unix-domain-sockets. The select runs on all connected sockets for read and
error, write is untouched.
In testing-enviroment everything works perfect, but in production-eviroment
the server hangs after some time.
Some facts:
- in testing, even 32.000 fast connects (made synchronous with 16 processes)
couldn't get the server to hang, in production it hangs after about 3000 -
7000 connects, regardless of low CPU-load
- debug-outputs to console before and after the select show clearly the
socket_select() is hanging
- tried both blocking and non-blocking select, same effect in both cases
- both test and production are on the same machine, same PHP
- both are getting only local connects from other PHP-scripts
- socket-dumps before the select show all sockets in normal state, even if
directly before a hang
- select hangs sometimes with about 80 synchronous connections, sometimes
with only about 20
I thought it might be a bug in PHPs socket-extension, because the hangups
come random, indipendent of number of synchronous connects, number of
processed connects, id of hightest socket-descriptor, used CPU-time.
Maybe i just forgot something, but it doesn't go into my head why it hangs
exactly during the select :-/
The code should be okay, it is basically indentical to an example posted
some time ago in the php-dev-mailinglist (i've pasted it below).

[PHP] Memory-Size of Objects
Hi, does anybody know a way to get the memory-size of an object? I'm triing to seek some memory-leaks in a php-daemon-program wich cannot be reproduced easily to track them down, so i thought to monitor the size of the objects while running in a production-enviroment.
