[PHP] Best way to manage open slots for download
First of all, Happy New Year for everyone in the list. I wish 2007 brings
all us happiness, health and peace.
I want to read your advises at a point i am stuck within, i have an
application that serves downloads to clients. For some reason i am limiting
total open slot for some group of users (not related to my technical
question).
Example;
// CHECKS SLOT HERE
else { // IF THERE ANY AVAILABLE SLOTS SEND THE FILE
// INCREMENT SLOT NUMBER BY 1
$fp = fopen($pathside,"r");
if ($fp) {
while (!feof($fp)) {
echo fread($fp, 334);
$bytes_out += 334;
ob_flush();
if ($bytes_out > $size) {
// DECREASE SLOT NUMBER BY 1, BECAUSE THIS DOWNLOAD IS FINISHED
}
}
}
}
Slots are recorded and checked from a simple mysql table. Everything works
in this scenario. There is no problem if a person starts a download and
finishes it, his slots get empty upon doing so. Yet if he cancelles the
transfer, he will never reach my control structure to empty the slot. And
slots will be full of zombies.
I have thought of updating a mysql field for alive-connections in the while
loop, but it will definitely add some load on my server. Updating a system
file is not secure and good way.
What other ways can you recommend to me for the situtation?

RE: [PHP] PHP Sockets - How to detect client disconnection?
I used Process Control Functions in PHP and installed some signals to catch socket disconnection. My attempt to do this in loops were a harder way or i could not manage it. There must be some notes about this in archives or i can send some of my code so that you can have a look at them.

How do I detect a disconnected client from a socket resource? In an infinite loop, I socket_read() every open resource that passes a socket_select(). As far as I know, the only way to detect if the client disconnected unexpectedly from their socket resource is when socket_read() returns FALSE (which, during my testing, produced the warning: "An established connection was aborted by the software in your host machine."). However, socket_read() doesn't return FALSE on a disconnected client's socket resource until I first attempt to socket_write() to that resource. In brief pseudo code... socket_create(AF_INET, SOCK_STREAM, SOL_TCP) while (TRUE) foreach (resource where (false === socket_select($arrayofresources, NULL, NULL, 0, 0)) if (socket_read() === false) WON'T DETECT DISCONNECT UNTIL I FIRST socket_write() I appreciate any support you offer and thank you for your time.

RE: [PHP] remote fopen not working, despite allow_url_fopen = on
I do suppose this as a networking error rather than a php problem, or a bug which may be caused by your current combination of OS and software set. By the way, allow_url_fopen is set to OFF, not ON, as it is in the attachement of phpinfo in your previous mail. That would produce a different error i know, but an apache restart may be one more trial for this to work.

[PHP] signal handling
Hello Despite all of my results to succeed, i can not make this work. What i want to do is to write a simple socket server in PHP. My current example just prints the same character, you send to server from keyboard. It is successfull in forking, and generates child as people connect. However in any way the client exits, the child process remains defunct on system. I am trying to use signal handling, but some comments say through hanging sockets, it is not possible to handle signals. How can i stop this from happening, i am attaching the code i am working on, the 2 signals added at the bottom are just for test there, i tried all other signal types. Sending a posix_kill(posix_getpid(), SIGKILL) to the process when the client exits does not kill it too, it still is defunct. My code: http://pastey.net/2910 Thanks!

[PHP] Do Sockets Cache?
Hello :) Wonder someone can save some of my hair here. I have a daemon application listening as root on my linux server that i have written in PHP. I use it to communicate web user with the backend linux to make certain operations from web interface. I have a login/verify command that i send to socket server to log in. I send raw command something like (login user hash) ; client command -> login admin Fjsdla5dk2mDke server response -> YES/NO Server reads from a plain text file containing user/hash and gives yes or no. But it is working like a lottery, sometimes yes sometimes no through WEB. When i test through shell, telnet or etc. it is fine, through web it sometimes outputs YES, sometimes outputs nothing (does not give NO), like it is not even connecting or getting no response at all. I have test mechanisms for valid connection and data send. So i get this crazy idea of caching for connections on web.

RE: [PHP] calling a function in the same page
You can not call PHP functions through a href which is used for linking web
pages.
You need to create a new file or use a switch in your current file for
search input,
with the function in it. So that you can link to that URL, not the function
itself.
You can use AJAX as well, to send commands to a php file and get the results
in xml/text,
but again you need to call Javascript there, your logic is totally wrong.

Is this for the client application or server?
