[PHP] Increasing maximum file descriptors (OS X Lion 10.7, PHP 5.3.8 via Macports)
I have a working socket server in PHP that I wish to improve (allow for more socket connections). I am running into a limit I can't crack, related to the max number of incoming socket connections. Using Macports for package management... I've recompiled PHP with the --enable-fd-setsize=2048 in the port file) … but I still get the following PHP warning once my socket server tries to accept more than 1024 clients (800, 900 are okay): PHP Warning: socket_select(): You MUST recompile PHP with a larger value of FD_SETSIZE. It is set to 2048, but you have descriptors numbered at least as high as 1027. --enable-fd-setsize=2048 is recommended, but you may want to set it to equal the maximum number of open files supported by your system, Weird right? Shows I have it set in PHP, so maybe it's a resource limit? But having changed sysctl.conf, ulimit -a shows: core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 2048 pipe size(512 bytes, -p) 1 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 709 virtual memory (kbytes, -v) unlimited So I should be able to have up to 2048 files (sockets) open, but PHP still complains. What am I missing? Any ideas what I should try next? ...Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] file_get_contents ($file) works -- file_get_contents ($url) returns false
Well thanks for trying. For anyone reading this, who wants to be a hero and
solve the impossible:
1. file_get_contents ($url) doesn't work -- (on remote URLs or local URLs)
2. file_get_contents ($file) works.
3. CURL works (on remote and local URLs).
4. as per php.ini, allow_url_fopen On
Xserve
- OS X Server 10.6.2
- PHP 5.3 (default)
So... it's as if PHP is not respecting the allow_url_fopen direction in
php.ini. If that directive were set to Off, everything would make sense (files
load, urls don't (local or remote)).
Anyone have anything to add? Anyone, anyone?

Use Curl to get in the file contents. Check your PHP that Curl is enabled.

that is stopping you form getting in the content externally.

The thing is, the file_get_contents() fails the same way on local URLs --
that is, web sites hosted on the same machine. Or even using the machine's
own IP address.

This problem can be caused due to one of the following-

Don't think this is it, since (1) the firewall settings haven't changed,
and (2) other machines on the same network can execute this same code and

3. Some times the remote host does not allow you to connect to get the

(I say and/or because I am unsure where the problem's cause really lies.) Basically, after the script has been running for a day or so (processing essentially the amount data that used to take two weeks), the CPU usage of the machine goes from 30% (normal) to 80-90%. Have you tried stracing it to see what's really happening when the load goes that high? Good advice, since I think there's nothing left for me to do but inspect the MySQL process. Incidentally, I've made some changes to the script a week ago, which has seemed to improve the situation somewhat. Now, the script has run for nearly 7 days without interruption or high CPU load. Problem solved? Again this morning, I noticed CPU went up to 90% and is staying there. (Previously, this would happen after 1-2 days.) The number of distinct MySQL connections remains low, since the script (which runs in a loop, with a sleep(1) and a timeout on the stream_socket_select()), only creates one MySQL connection in the beginning. All MySQL queries run through that. The script has run for 6-7 days, during which time it's executed 2.7 million queries (mostly SELECTs) and created 105,198 external, short- lived child processes (each lasts about a second or two, then closes after mysql_close())--I don't think this is an issue. Memory usage seems okay. By the end of 7 days, the script's memory usage has peaked at 4MB (out of 16MB max). Typically it's around 3MB. MySQL memory usage doesn't seem to be a constraint. I'm using my- huge.cnf, and the nature of the queries is fairly regular. I would say that the database structure is not an issue (though I could be wrong!)--everything is pretty well normalized and indexed. I'm logging slow queries, non-indexed SELECTs, etc. I'm really not sure what to try next. ps -aux shows MySQL as hogging the CPU, not PHP or Terminal: PID COMMAND %CPU TIME #TH #PRTS #MREGS RPRVT RSHRD RSIZE VSIZE 342 mysqld 83.3% 16:13:19 33 125 139 435M 4.75M 439M 539M 385 Terminal 4.7% 5:36:35 22 184 251 20.1M 33.5M 28.8M+ 256M 1190 php 4.3% 3:13:33 1 15 148 6.51M 8.15M 12.1M 89.0M 0 kernel_tas 1.3% 2:02:40 47 2 619 5.00M- 0B 219M- 1.26G- It's really strange and strangely consistent.

Re: [PHP] Command-line PHP script CPU usage goes sky-high, stays there--why?
That makes sense, but I'm not sure I really want to do this, since it's fairly important that Listener continue listening without interruption. I also don't think it's probably necessary, since from what I read, I'm not really pushing the envelope in terms of real load. Right now, I might have max ~250 clients connected, each sending 5-20 kb / day of data. It's not much data, nor many concurrent connections. If Jim's Listener handles 80-85k connections per day, then mine should be able to do 250 concurrently easily, and 2000 cumulative per day without a hitch.

[PHP] Bug in stream_socket_server()?
If you want a high speed socket server, use the low-level sockets instead (socket_create/bind/listen). The stream_socket_server version appears to have internal fixed 8k buffers that will overflow if you don't keep up by reading. This is a serious problem if you an application that reads the socket for messages and then, say, saves the result in a database. The delay while it is busy processing means you can't read the data in time unless you get involved in muti-threading. With the the low-level functions, the OS quietly buffers TCP/IP packets so there is no problem (tested on Windows XP Professional). ( http://php.oregonstate.edu/manual/en/function.stream-socket- server.php#67837 ) Has anyone confirmed this? I am doing tests with a stripped-down multi-client socket server, wonder if this issue is causing some of the problems I've seen. ...Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Command-line PHP script CPU usage goes sky-high, stays there--why?
Hello, I have a command-line PHP script--called Listener--that is designed to run indefinitely with a predictable CPU usage and memory footprint. In a nutshell, it's a multi-client socket server that waits for incoming connections, processes incoming data, stores results in a MySQL database, and basically gets on with its life. And it works. No errors or serious problems to speak of. And I've been running it for a couple years on an Xserve dual-G5 2GHz w/ OS X Server 10.4.11). Six months ago, the program would run for days, even a couple weeks, without a hitch. The only reason I would stop the script is for some other purpose, like a software update. However, the number of socket clients connecting in the past 3-4 months has steadily increased, and this seems to have exposed (if not created) a strange performance issue with PHP 5.2.4, MySQL 5.0.45 and/or Mac OS X Server 10.4.11. (I say and/or because I am unsure where the problem's cause really lies.) Basically, after the script has been running for a day or so (processing essentially the amount data that used to take two weeks), the CPU usage of the machine goes from 30% (normal) to 80-90%. This appears to be irrespective of the number of clients connected to the server at the time, but rather the amount of time the script has been running (and therefore cumulative cycles it's operated, data processed, MySQL queries executed, etc.). And the CPU usage stays high, even when the actual load (number of clients) decreases. At this time, if I run top, I get the following info: 22512 mysqld 91.6% 8:22:12 31 106 125 305M+ 3.20M 260M 475M 17104 php 7.2% 81:14.01 115 145 5.08M 7.80M 10.9M- 87.5M 22537 Terminal 6.6% 2:59:59 22 176 240 12.3M 21.2M 18.3M- 236M [...] At first I thought, okay, it's MySQL's fault. Maybe a lot of slow- running queries. But the slow query log is pretty clean. So maybe it's a combination of Mac OS X and MySQL and PHP? I Googled for a similar problem, and finally ran across this article: http://www.shawnhogan.com/2005/10/mysql-problems-on-mac-os-x-server.html ...where the author describes a very similar CPU usage pattern. I tried his suggested fixes and they seemed to have helped a little (or maybe it's my wishful thinking--hard to tell), since the high CPU load issue doesn't appear to happen as soon... But it still happens. Anyway, I'm really stumped as to what to do next, where to look, etc. If I stop the script, and restart it (but not the MySQL itself), CPU usage goes back to normal--for about a day or two. The only thing I thought might be connected is how many short-lived PHP child processes Listener creates--around 20-30,000 per day. Sounds higher, but on average it's just one every 2-3 seconds. Anyway, although the number of child processes isn't concurrent, would there be a problem with the number of historical child processes in view of ulimits or kern.maxfilesperproc? Anyway suggestions, tips, or links are much appreciated. Thanks. ...Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Command-line PHP script CPU usage goes sky-high, stays there--why?
Hi Jim, I have a server that listens like yours does. I get 80k - 85k connections a day to it. When I first started it, I was only getting about 3k of connections aday. Then I upped the listening pattern and it tanked. I noticed that all my mail/web/db connections just sat there. When I investigated, I found that the number of connections to the server was being overloaded. So I increased the kern.maxfilesperproc setting to 32000. All the problems went away. I have about have the horse power you do, running OpenBSD 4.1, and it runs great now as my listener / web / ftp / mail / named / database / spam filter / etc... One question about the listener program, does it maintain a connection to the DB or does it open/close a connection upon each socket connection? If it does the latter, you might look into using a constant connection rather then opening/closing on a per connection basis. Thanks for the reply. (Not many people seem to be doing what I'm doing in the way I'm doing it... so I really appreciate the feedback.) I don't think the kern.maxfilesperproc setting is a problem. I'm currently set to 102400 per Shawn Hogan's advice. And my Listener program only receives ~1000 connections per day. However, each connection involves multiple MySQL queries, often as many as 50 or so per connection each day. So perhaps your second observation applies. MySQL is showing ~ 1,500 connections per hour. And I'm using mysql_connect() in Listener. I will see if using mysql_pconnect(), and reducing the number of connections helps. My.cnf's max connections, presently at 100, may have been too low in view using mysql_connect(). If mysql_pconnect() doesn't improve things, maybe I should bump up max_connections to 500? ..Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

On 10-Dec-07, at 4:42 PM, Tom Rogers wrote: Put a usleep(1000) in the listen while() loop and give the cpu a break. Good advice, but I've already been doing that. The thing is, when the script first starts up, the CPU rarely exceeds 30%, even when many clients (200+) are simultaneously connected and sending data. When a few clients are connected, CPU is typically below 10%. Again, it's only after 24-48 hours that, all of a sudden, CPU usage increases by 40-50%. And it stays high until I stop the script and restart it. One question I have though is, is there actually any benefit to using mysql_pconnect(), since the script simply loops? My understanding is that pconnect only benefits if a script would otherwise be using mysql_connect repeatedly--and this script doesn't, since it calls mysql_[p]connect() just once, in the start tof execution. ...Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This makes me think about asking if you have to short of a timeout
on your receiving connection?
One second on stream_socket_server(), with a 900 second timeout
stream_socket_accept().
What are you using to setup your connection? fsockopen() or
stream_socket_server() ?
here is a snippet of what I have
[...]
Thanks for sharing your code. Seems pretty similar to mine at first
glance.
I don't have a timeout set on the *_recvfrom() call. I just wait
until the next connection comes in.
You don't need to use mysql_pconnect(), especially if you are
using, what in essence is, a daemon.
Yeah, after thinking about it, that's what I figured. Thanks for
confirming though.
Just don't open and close the connection constantly, leave it open.
Yes, I just open it once at the top of the script. And that's it.
Also, make sure you are not using an array that you are not re-
initializing through each iteration
of the loop. If the array keeps getting bigger, PHP might $*% on
itself. Always re-initialize
arrays to clean them up.
Hope some of this helps!
All good advice. I will check my arrays, although I don't think this
is a problem since I monitor the scripts memory usage with
memory_get_usage() and memory_get_peak_usage(), and it never tops 3MB
(max allocated is 16MB). There are a few little parts to the daemon.
One thing I'm doing that could be problematic is running an include
(); on a couple files each time a socket has new data (this allows me
to adjust the processing logic on the fly without having to start the
script and wait for clients to reconnect)--but I can see this being
expensive in terms of performance and resources. Actually, I wonder
if THAT is not what's starving the script of resources over time--
each fread() involves several includes(); I'll have to look into that...
FWIW, here's the stripped-down skeleton of the server:
As always, constructive criticism is very welcome.

[PHP] Multi-threaded port listener
Anyone find any good tutorials, code samples, etc. on such a thing? Basically, I want to write server (in PHP) that listeners on a particular port, and spins off a thread/process (essentially, execute a separate script) for each incoming connection. There won't be a lot of data to process, but there will be many simultaneous connections— upwards of 1000s of connections (each spun off as seperate threads). ...Rene
[PHP] Possible?
Simple problem: Many client apps need to send data to a server. By default each client will open a persistent TCP socket connection to a common IP address:port (10.10.10.10:1234) and write to it (which the server will save/log, etc.). My question is, what should be ready to listen at the IP:port? I was thinking of writing a PHP command-line socket server that listens at that port. But there will be a potentially huge number of clients connecting simultaneously (1000s), not transmitting a lot of data per se, but a lot of connections... Anyway, instead I thought writing a simple PHP script—say, listener.php—that gets executed by the web server and enters a socket_read loop until the client terminates the connection (set_time_limit(0)). Does this sound like a good way to do it? This way, Apache handles all the connections, and PHP is instantiated each time, but without having to fork processes, etc, and without having to do PHP CLI. Anyway, I've started looking at this, but I'm not quite sure if it's even possible. I mean, can something send a request to Apache, and continue to write data along that TCP socket? Normally, HTTP requests include GET or POST for such data, but this is not a a web browser that's opening the connection. Hope I'm somewhat clear. Just struggling through some options here Anyway, thanks in advance for any suggestions. ...Rene

Well, not if the client (actually, it's a pre-programmed physical device) is set to always open a socket connection to 10.10.10.10:1234... right? But rather than write a client and a server application from scratch, why not just use HTTP POSTs? I'm not writing the client, I just need to make a server that can accept numerous simultaneous incoming socket connections, and maintain them. Maybe stream_select() as someone suggested? I suppose my question would be, can a single PHP socket server script, executed from the command-line, maintain 1000s of concurrent connections (there is not a lot of data incoming, btw)? ...Rene

[PHP] Can this code go faster?
I've looked in the docs and don't see anything for this per se...
I need to convert a binary number of arbitrary length to a signed
integer.
This is how I'm doing it now:
CODE
function bin2int ($bin) {
if (substr($bin,0,1) == 1) {
$val = 0 - bindec(substr($bin,1)); // NEGATIVE
} else {
$val = bindec(substr($bin,1)); // POSITIVE
}
}
echo bin2int(1101).'br /';
echo bin2int(10001101);
OUTPUT
13
-13
As you can see, if the most-significant bit is 1, then the rest of the
value is negative. If the first bit is 0, then the rest is positive. Is
there a better, faster (execution-wise) way of doing this? Maybe a more
built-in function of PHP I missed? It's something that my script will
be doing thousands of times, so I am concerned about speed.

Re: [PHP] How to make a PHP Socket client crash-proof?
I managed to solve the problem with the socket client hanging when the
Server disappears.
Actually, it is not hanging. What I discovered is that once the other
end of the connection drops, it starts/continues reading on that socket
ad infinitum. (I put a little counter in it, and can watch it count
up). What I did to stop detect a gone connection, and then restart the
socket, isn't elegant, doesn't use a socket_select() or non-blocking,
but it DOES work.
$i = 0;
while(($buf = socket_read($socket,1,PHP_BINARY_READ))
!== false) {
echo $i. \n;
$i++;
$data .= $buf;
if(preg_match(/EOF/,$data)) {
$msg_recv = 1;
break;
}
if($i1) {
$connect = false;
break;
}
}
Still, one day I would like to re-architect this. Seems a bit hackish.

They can both use your local database to share data, to whatever degree
you deem necessary, but having one-way sockets for two different
scripts
is way more easier than trying to get a two-way socket to work, in my
(limited) experience.
If you MUST push forward with a two-way socket, try to determine the
state
of the world inside your infinite loop. Why aren't you breaking out of
that loop? Can you do *anything* to break out?
I suspect that once you have started SENDING data to the server, it's
going to just keep waiting for you to send more. How do you signal the
end of your data to be sent? Does the server understand that signal?

[PHP] How to make a PHP Socket client crash-proof?
Hi all, I have a Socket Client that connects to a Server. (It is not multi-socket or multi-anything.) It is VERY simple. How it works: 0. CLIENT connects to SERVER. 1. CLIENT waits for incoming data. 2. If there is no data for a while, CLIENT sends a ping to the SERVER. 3. If the SERVER responds, CLIENT continues waiting. 4. If the SERVER doesn't respond (and a few seconds pass), CLIENT closes socket and restarts (Go to Step 0.) 5. Once in a while, CLIENT must send some data to the SERVER 6. If the SERVER acknowledges the data, CLIENT begins waiting again for data from the SERVER (Go to Step 1.) 7. If the SERVER doesn't acknowledge, CLIENT closes socket and restarts (Go to Step 0.) In a perfect world, the above script would run forever without trouble. Unfortunately, the world is not perfect. Sometimes, the Server dies or disappears unexpectedly, at which point my Client hangs and starts consuming 100% CPU. (The problem.) As I understand it, I must change the Client in a couple ways. 1. Set the Client's socket to NON-BLOCKING, so that it doesn't hang the script when the Server up and vanishes. 2. Use SOCKET_SELECT(). Now, I've read the docs and several good tutorials code examples, such as: http://us2.php.net/manual/en/function.socket-select.php http://us2.php.net/manual/en/function.socket-set-nonblock.php http://dave.dapond.com/socketselect.php.txt http://labs.jed.bz/HCJ/load.php.txt http://www.amk.ca/python/howto/sockets/ sockets.html#SECTION00051 http://www.catalyst.com/support/tutorials/tcpintro/page9.html Unfortunately, all examples appear to differ from my Client in very one important way: They do not contain lines 5-7. None of them have to periodically stop listening for incoming data and check if they need to write to the socket (like mine does). My Client MUST periodically check a database for new messages waiting to be sent. If there are any, it must write them to the Server. In my old code (which hangs when the Server disappears), I simply set the socket to blocking and give it a timeout of a couple seconds. So, every two seconds the Client times out, checks if there are any messages to send to the Server, sends them if there are, and then returns to waiting If it helps, I can post snippets of my code, before (working, but not crash-proof) and after (not working at all, just looping endlessly, really fast).

[PHP] Socket trouble
I'm having some trouble with my socket client. I would like it to
notice when the server is no longer there, and then reconnect. I have
code for the reconnect, etc., but I can't figure out how to write the
socket_read code so that it notices when the server is gone and then
responds. Presently, my client just hangs (CPU goes to 100%, nothing
happens.)
Here's my code:
while(($buf = socket_read($socket,1,PHP_BINARY_READ)) !== false) {
$data .= $buf;
if(preg_match(/TERMINATING/,$data)) {
$msg_recv = 1;
break;
}
}
The PHP docs on socket_read suggest how this might be done:
Note: socket_read() may return a zero length string () indicating
the end of communication (i.e. the remote end point has closed the
connection).
Does this end of communication include cases when the socket server
dies without gracefully disconnecting? How could my code check for this
zero length string? Any help is much appreciated. Thanks!

I guess a better question would be, what is the best practices way of showing a Please wait... page while a server operation is performed (which could take 5 or 45 seconds), then make the page display the resulting data (via reload, or slow-load, or whatever)? Would love to find an article on this. ...Rene On Wednesday, June 9, 2004, at 05:56 PM, Michal Migurski wrote: When Expedia.com is searching for flights, it displays a page with a little animated GIF progress bar, then display the results.

I was thinking that they might use HTTP-REFRESH or something, and just keep hitting the database until the result is there. But is there a best way to do this? In my application, when the user clicks a certain button, it will take 10-20 seconds for the operation to completeduring that time I need the web browser to waiit for the data. The progress bar goes by too quickly for me to tell, but perhaps they are using a slow-loading resource someplace on the page? E.g., an image whose content-length is 64, whose 64th byte does not get sent by the server until the query is complete. Combine that with a bit of javascript waiting for the image to load, and you should have basic loading-bar behavior. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Can someone explain this?
OK, that makes sense. But here's the problem: I receive binary data
from SuperSPARC (big-endian), which I need to unpack according to
certain documented type definitions. For example, let's say that $msg
has the value 3961595508 and is packed as an unsigned long integer
(on the remote SPARC). But when I receive it, and unpack it...
$unpacked = unpack('Nval', $msg); // N for unsigned long integer,
big-endian (SPARC)
echo $unpacked[val];
...the output value is -71788. (???) Which tells me that PHP is
NOT unpacking $msg as an unsigned long integer, but rather as a signed
integer (since unsigned integers cannot be negative).
Now, thanks to your suggestions, I can convert that number back to an
unsigned integeror at least make it positive. But I shouldn't have to
convert it, should I?

You have it backwords.. -71788 is signed and the 3961595508 is
unsigned.
But...
?php
$dec = -71788;
$unsigned = sprintf(%ul, $dec);
print $unsigned; // == 3961595508
Do note that php doesn't have native unsigned numbers so doing
something like this wont work right:
printf(%d, $unsigned); // == 2147483647
So to convert it back you have to do something like:
printf(%d, $unsigned+0); // == -71788

[PHP] Mapping solutions
I'm looking for a good mapping solution for a PHP project I'm working on, and wondered if any of you would be able to recommend one. Basically, I would like to be able to pass this Map Module several values: Latitude, longitude, map scale (e.g., 5KM x 5KM), and map resolution (500 pixels x 500 pixels), and have it return a GIF or JPEG which I can then send to the user's browser. (Additionally, it would be useful if I could pass more than one set of latitude/longitude values and have the map software display multiple points on the same map.) It seems unlikely that I could get my Host Provider to let me run third-party software like this on their servers, so I would probably have to install it on my ownwhich would likely end up being a Mac OS X box.

[PHP] Blocking vs. Selecting
MY PROGRAM FLOW:
Enter loop
Wait incoming data
If (incoming data) {
do something
} elseif (no data delay 5 seconds) {
send ping to server
return to top of loop
}
Of course, it's very simple. :-) But to make it work, I think I need
to choose:
1. Timeout the socket_read() (nonblocking socket, etc.)
or
2. Use socket_select.
Here's my question: I have only one socket active in this application
at any time. Is it appropriate to use socket_select with just one
socket connection? And if I stop deselect that socket, and the server
sends data while the scirpt is doing something else, will the data be
lost, or will it wait o be read again once the script can give its
attention to that connection?

No, it doesn't fail the first time. It runs through the loop several
times, and fails ONLY once it timesout (because the server is sending
no more data). Then, the next time it loops, it fails again.
That said, I am going to shortly repost the program flow (in simplified

Hi Warren,
There is only one process, and I'm sure I have only one IP address.
It's just one script that loops. At the top of the loop, it waits to
socket_read some data. If no data appears, I want it to timeout so that
it can send the server a ping (which I must do). THAT is where the
problem starts. If I don't bother making the socket_read timeout, the
loop works beautifully-it just waits and waits at socket_read, and then
when data appears, it does its thing, then goes back to the top of the
loop and waits again. It's when I set the timeout option, and then it
DOES actually time out (because there is no data for several seconds),
that it no longer is able to socket_read data from the connection.

[PHP] Socket client can do one thing (loop), but not the other (loop, timeout, loop again)
Hello everyone,
I really appreciate the suggestions so far with my socket client
problem. Somebody suggested I repost the issue with the program flow
and code, to clarify the situation (a good idea). So here it is:
To sumarrize: My socket client runs fine when all it does is (1) wait
for data from the server (2) respond to server message (3) then wait
again (ad infinitum). E.g.,
---THIS WORKS--
Setup and open TCP socket
Send a Password_DS to the Server
Send a Resend_DS to the Server
Enter infinite loop:
Wait for messages from the Server
Upon receipt of a Send_DS from the Server
Respond with a Send_DS_Ack
Upon receipt of a Ping_DS from the Server
Respond with a Ping_DS_Ack
Upon receipt of a Status_DS from the Server
Respond with a Status_DS_Ack
---THIS WORKS--
Again, the client loops fine and works wellUNTIL I I try to add one
feature: If the Server doesn't send a message for more than five
seconds, the socket_read should send Ping_DS to the Server to see if
it's still alive, and then, if it is, continue to the top of the loop
and wait for another message from the Server.
---THIS DOESN'T WORK--
Setup and open TCP socket
Send a Password_DS to the Server
Send a Resend_DS to the Server
Enter infinite loop:
Wait for messages from the Server
Upon receipt of a Send_DS from the Server
Respond with a Send_DS_Ack
Upon receipt of a Ping_DS from the Server
Respond with a Ping_DS_Ack
Upon receipt of a Status_DS from the Server
Respond with a Status_DS_Ack
- Periodically, send a Ping_DS to the Server
- If the Ping_DS transmit fails
- Clean-up and restart the socket connection
- If a Ping_DS_Ack is not received from the Server
- Clean-up and restart the socket connection

Re: [PHP] Socket looping challenge
The script doesn't even get that first while condition line. It loops
a few times (while receiving messages), then when no more messages are
coming from the server, and it times-out, it breaks out of the while,
then returns to the top again, where it that while condition returns
the error Warning: socket_read() unable to read from socket [35]:

This line...
while(($buf = socket_read($socket,128,PHP_BINARY_READ)) !==

Re: [PHP] Why would a socket be unavailable?
Hi Warren,
There is only one process, and I'm sure I have only one IP address.
It's just one script that loops. At the top of the loop, it waits to
socket_read some data. If no data appears, I want it to timeout so that
it can send the server a ping (which I must do). THAT is where the
problem starts. If I don't bother making the socket_read timeout, the
loop works beautifullyit just waits and waits at socket_read, and then
when data appears, it does its thing, then goes back to the top of the
loop and waits again. It's when I set the timeout option, and then it
DOES actually time out (because there is no data for several seconds),
that it no longer is able to socket_read data from the connection.
...Rene

Can
you confirm that both of your processes are using the same IP address

the ip address of the other process)?

[PHP] Constant questions
Hi,
I have two questions involving Constants.
1. I want to refer to a refer to a Constant by its value (which is
unique), and return its name. E.g.,:
define (SEND_DS,1);
define (SEND_DS_ACK,2);
define (RESEND_DS,3);
define (STARTUP_DS,12);
For example, if I receive 3, I would like to echo RESEND_DS--the
name of the constant. Is there a simply way to do this? Or am I better
using an Associative Array (which is what I was thinking)? Then I could
such refer to an element by its key or value (both of which are
unique). I suppose this more of a performance/elegance issue, than
outright problem. Just curious what you think.
2. Let's say I have a Constant called MY_NAME, the value of which is
Rene, and I pass it to a function, such as:
function example ($val) {
echo ???;
}
example (MY_NAME);
Such that the output will be MY_NAME. If I echo $val, the output will
be Rene. But I want to see the constants Name, not Value. Any ideas?
Thanks.

[PHP] Breaking out of a loop...
Hi,
I have this code (below) that waits for particular data to come over
the socket (ENX), at which point it breaks out of the loop and does
other things. Presently, it will loop forever, until it receives
ENXa good startbut I also need it to break-out if the loop runs
longer than five seconds. This is where I'm having a problem. It seems
that it is only reading once data comes over the socket, so it is stuck
on that first 'while' line (while(($buf =
socket_read($socket,128,PHP_BINARY_READ)) !== false) {).
$timer = time();
while(($buf = socket_read($socket,128,PHP_BINARY_READ)) !== false) {
$data .= $buf;
$elapsed = time() - $timer;
if(preg_match(/ENX/, $data)) {
break;
} elseif ($elapsed 5) {
echo TOO LONG!\n;
break;
}
}
Maybe set non-blocking / blocking socket is the answer? Only problem is
I can't find much [good] documentation describing what blocking and
non-blocking sockets are good for, etc. Any ideas? Thanks.

Thanks for the help, but I now get the error PHP Warning:

/Users/test/cr.php on line 51 when I run the script. Also, it still
seems to just wait on that while line, instead of skipping to the }

want it to do). (Is it just me, or is the PHP documentation on
socket_set_block and socket_set_option a bit too sparse? I mean, where
do you find the docs on those options and values?)

blocking - wait for response or till timeout
non-blocking - return right away
If you use blocking and then set the timeout for the read, you can
just check for socket_last_error() after the loop.
socket_set_block($socket);
socket_set_option($socket, SO_RCVTIMEO, 5000); // milliseconds iirc
while(($buf = socket_read($socket,128,PHP_BINARY_READ)) !== false) {
//...
}
if ($error = socket_last_error($socket) ) {
echo socket error [$error]: . socket_strerror($error);
}
or something like that.

[PHP] To pack(), or not to pack()
Hi, I'm developing a PHP program that must send data, over a socket connection, to a server. The server requires the data in a particular format, e.g.: FORMAT: 3-byte delimiter - Message Length (N = 4 bytes) - Message Type (4 bytes) - Message Body (N - 4 bytes) - 3-byte Delimiter SAMPLE MESSAGE: STX00110018Hello WorldENX The sparse documentation *seems* to indicate that the message data must be in binary format. The reason I say seems is that the docs say the data must be in a particular byte order (bigendian, I think, 'cause the server is running on SuperSPARC). It also talks about default integer size of 32 bits, unsigned char, blah, blah, blahstuff I normally never worry about with PHP. All the sample code is in C, which I don't know. I'm a one-trick (PHP) pony. Now, as I understand it, socket_write($socket, $data) by default will send $data in ASCII formatright? But if I must send this message in binary, then would I use pack() to convert the ASCII to binary? ..Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] unsigned long int
I don't know C, but I was wondering if it is possible to: 1. Define 32-bit integer in PHP, called $val (max value of $val); 2. Assign the value of 10 to $val. 3. Pack $val to a binary variable ($bin_var); ...such that $val is only equal to 10, but it is occupying 32-bits of data... (In case you were wondering, am I quite lost, yes, I am.) ...Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Binary to ASCII
When reading from a Socket Server, my Socket Client retrieves data that
includes ASCII and binary data:
while(($buf = socket_read($socket,128,PHP_BINARY_READ)) !== false) {
$data .= $buf;
if(preg_match(/ENX/, $data)) break;
}
echo RESPONSE: .$data.\n;
The output looks like:
RESPONSE: STXThe system is up and running.ENX
Between the STX and The system is up... are 8 bytes of binary data
(which this case appear as an ampersand), which I want to extract from
$data, split into two 4 byte variables, and convert back into integers.
I suspect that I need unpack() at some point, but any ideas how to
extract and split the binary data from this string? (Sometimes, the
binary data is not visible, but it's still there.)

PS. Thanks guys for the earlier advice with pack()--which worked.

[PHP] Socket client application
Hi, I've gone through several good PHP sockets tutorials, but all of them seem to focused on making socket servers. What I actually need to do is write a socket client. There's an app runnning on a distant server that accepts incoming TCP connections at such-and-such an IP address and port, and then responds to various commands and issues standard responses, etc.---I need to build the app that talks to it. Now maybe I'm missing something really obvious, but I can't find any tutorials on what such a socket client app might look like. The client I need to build must maintain the connection once started. Any ideas?? ...Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] regular expressions
I'm trying to 'clean up' some text that is extracted from a web directory, and I need to use (I think) preg_replace or ereg_replace, etc. I've read a bunch of tutorials, but none of them seem to cover the particular thing I want to do. Here's an example of text I need to process: - J. Smith ( More Info ) map driving directions add to My Directory update or remove Did you go to High School with J. Smith? B. Dixon ( More Info ) map driving directions add to My Directory update or remove Did you go to High School with B. Dixon? M. Jones ( More Info ) map driving directions add to My Directory update or remove Did you go to High School with M. Jones? - The above is a string. I want to eliminate, for example, all the lines that say Did you... ?, but I don't know how to refer to them because they are each a little different (because of the name). I know regular expressions can do this, but I can't seem to wrap my mind around the necessary arguments... This being my first foray into regex. I've written feeble stuff like: $result = ereg_replace(Did you go\[a-zA-Z]\?,,$result); But of course it doesn't work. Any ideas? Thanks. ...Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Problems with imagejpeg
I have a function that [is meant to] check if an image is greater than a certain width and height, and if it is, downsample it. The checking part works fine. Downsampling is happening though.

[PHP] GD question
I want to write a function the creates a new image composited from a 3x3 tile. The idea is that the center tile will be a photo, and the surrounding eight images will constitute a border and shadow to the composited image. So... The eight border/shadow images will always be the same, but the center image will be unique. Anyways, I've been playing with GD functions for a little while, and would appreciate any suggestions on how to accomplish this. I haven't been able to find a good tutorial on this kind of thing specificallycompositing tiles of images into a single image. Any ideas? ...Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Sweet PHP backup / dump function for MySQL database
Right now, I'm using phpMyAdmin to periodically backup/dump a client MySQL database to a textfile (from which one can simply restore the database if it ever got corrupted). I'm also working on a super-simple CMS for the client to use themselves. I would like the client to also be able to easily backup his web site's MySQL database to a textfile and have that textfile emailed to whatever address he specifies. Sort of a two step approach: Enter email _ Backup and send database (click) I imagine someone somewhere has written a very nice function for doing this, which might take a few parameters, such as database, destination email address, etc. The main thing is that the function include complete inserts, extended inserts, backquotes, etc. Anyone have a sweet function like this they wanna share, and in so doing make the world a better place? :-) ...Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Copying an uploaded file...
Ah, man, I just found my problem, and do I ever feel stupid... Thought I'd share it to highlight the it's right in front of one's nose feeling: copy($_FILES['userfile']['tmp_name']... ...was a sample code snippet. I had just copied and pasted it without changing the userfile partand since there was no 'userfile' in my form, it would never have worked. Using my own variable pointer $fld works. Thus: copy($_FILES[$fld]['tmp_name']. ...works. And that is all. In any case, thanks for the suggestions. ...Rene On Wednesday, October 29, 2003, at 11:28 PM, John Nichel wrote: Ren Fournier wrote: I've added a path, but still no success Does your webserver (Apache?) have write permission to the directory you're trying to move the file too? -- By-Tor.com It's all about the Rush http://www.by-tor.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Copying an uploaded file...
I'm trying to get a little upload script working... But I can't seem to
copy the tmp file to my local web directory (btw, do I really need to
specify the path, or can I just use a filename, and the file will be
written to the same directory as the PHP script??). Anyway, here is
the code:
$realname = $_FILES['userfile']['name'];
if(copy($_FILES['userfile']['tmp_name'],
'/Users/rene/Sites/renefournier/titan/res/'.$realname)) {
echo $realname.' uploaded';
} else {
echo $realname.' could not be uploaded';
}
echo 'br';
echo name: .$_FILES[$fld]['name'];
echo 'br';
echo type: .$_FILES[$fld]['type'];
echo 'br';
echo size: .$_FILES[$fld]['size'];
echo 'br';
echo tmp: .$_FILES[$fld]['tmp_name'];
echo 'br';
Here is the output:
could not be uploaded
name: web_share.gif
type: image/gif
size: 13370
tmp: /var/tmp/phpNqigbO
Thanks for any ideas.

Re: [PHP] Copying an uploaded file...
Thanks John. I've simplified and improved the quote per your
suggestions, but still no dice. (I'[m running OS X 10.2.8.) Here is the
code:
// MOVE FILE
if
(move_uploaded_file($_FILES['userfile']['tmp_name'],$_FILES['userfile'][
'name'])) {
echo Success!;
} else {
echo NO!!!;
}
Here are the results:
NO!!!
Array ( [img_photo] = Array ( [name] =
apache_pb.gif [type] = image/gif [tmp_name] =
/var/tmp/phpvnTFqr [error] = 0 [size] = 2326
) )
Should the tmp directory maybe be set elsewhere? (If so, how can that
be done? I've looked at the httpd.conf file, but there is no entry for
upload tmp directory.)
Many thanks in advance.

[PHP] Tricky variable syntax...
I'm trying to refer to a variable using $$, but with a twist. So far, this works: echo 'temp file: '.$$fld.'br'; In this case, $fld equals img_photo (although it could be anything). The above statement could have thus been echo 'file name: '.$img_photo.'br'; with the same results. So here I actually echo the value of the variable $img_photo. This is what I want. But here's my problem: echo 'file name: '.$$fld_name.'br'; What I want to do is echo the value of $img_photo_name. But how can I refer to it?
