[PHP] AMF PHP
Hi! Did any of you guys work with AMF PHP? I have been using AMF PHP for flash remoting and I am unable to propagate cookieless sessions from my web application to flash. Any suggestions? I am using Tufat.com's AMF Flash Chat as the flash app. Regards, Yaswanth -- In theory there is no difference between theory and practice.

[PHP] PHP and Flash Remoting
Hi!
I am using amfchat from tufat.com, and wanted to integrate it with my
site's session data. amfchat uses flash remoting to communicate to the
server.
It initally sends
sessionid=time() to gateway.php
gateway.php starts a session using:
function session($name=false){
if($name){
$prev_name = session_name();
if($prev_name != $name){
session_name($name);
}
}
@session_start();
}
And accesses the session variables in another function thats called
using flash remoting.
as $_SESSION['username'];
I wanted to replace all this and I have made gateway.php start a
session as follows:
$prev_name = session_name();
session_start();
But I am not able to access my session variables in the functions
using $_SESSION['login']
This is the function I have modified:
$session_name = session_name();
session_start();
$username=$_SESSION['login'];
$password=$_SESSION['passwd'];
$result['description'] = User= $username, Password: $password,
Session: $session_name
When flash prints the 'result' arrary, the output for description is as follows
User= , Password: , Session: PHPSESSID
Can any one tell me if I am making a mistake some where or give me a solution?
Regards,
Yaswanth

[PHP] SQL Password() function
Hi! Is there a function (or a code snippet) in PHP for mysql password() function? I 'dont' want to use something like select * from table where table.passwd=password($passwd); Is there any other alternate way to do it?

[PHP] Server Client Architecture, best parctice
Hi! I would like to know what does the community think of the best architecture for server client communication and why? That is, if there is a server in C++ (say a game server) and the PHP has to 'read' data 'from' the server then what is the best form of communication? a) Shared Memory : Server opens the shared memory in write and the PHP scripts open it in read and gets the data b) TMPFS (just like shared memory): Server opens a file in tmpfs in write and PHP in read c) Databases: Server Updates a table in the DB and client reads from the table d) Files: Same as TMPFS Regards, Yaswanth -- In theory there is no difference between theory and practice.

Re: [PHP] Shared Memory Problem
Hi!
There is a strange problem now. This is the error message my php file gives.
kernel not configured for shared memory kernel not configured for
semaphores kernel not configured for message queues
The source is as follows:
?php
$shm_id = shmop_open(5678, a, 0, 0);
if (!$shm_id) {
echo Couldn't create shared memory segment\n : $php_errormsg;
}
print br;
print system(ipcs);
?
when I logged into my machine as user apache and tried ipcs command it
was working fine (I changed the shell of apache from /sbin/nologin to
/bin/bash)
Any clue??
Regards,
Yaswanth

The last one the the sharedmem the php will be using. the key is 5678
and as you said I
have modified my code to
$shm_id = shmop_open(intval($shm_key), a,666,0) or die(FATAL

U obtain the shm_key from a file. The key I am using is 5678 and it is
getting that value from the file. I even hardcoded the value, but the

You might want to try to open it within the same mode that the
server created it in:
1)
$shm_id = shmop_open($shm_key, a,0666,0);
2)
are you 100% sure the key is valid? the error message you are
getting seems to point in this direction since the shmop_open is
failing on the C call to shmget(), wich usually fails when either
you dont have enough memory to create it (which you arn't doing),
some other creation problems, or that the key supplied wasn't
found.
Curt.

Re: [PHP] Shared Memory Problem
Hi! I found the solution to my prob. SELinux was enabled in the server which needs disabling. After disabling SELinux it was working great. Thanks for your help guys. Another small query though, is there anyway to enable SELinux and as well use shared memory between PHP and C++? I know using Zend engine would solve the prob, but we need to buy zend which is very costly for me, any other solution is welcome.

[PHP] Shared Memory Problem
Hi!
I have a server written in C++ and my webpages are in PHP. The PHP has
to communicate with the server using shared memory. This was working
fine on the server running FC-1 with php-4.3.8. We recently migrated
to CentOS 4.1 (Equivalent to RHEL 4.1) running php-4.3.9. The error it
displays is as follows:
shmop_open(): unable to attach or create shared memory segment in
/var/www/html/sharedmem.php on line 2
The server opens the shm in 666 (originally was 644) even then it was
not working. I can see the shared mem open using 'ipcs' command.
The source code of PHP is as follows:
?php
/*Sem Key is read from this file*/
$SEMROUTE = /var/www/html/sharedmem/;
$filename = $SEMROUTE.id;
$handle = fopen($filename, r);
$contents = fread($handle, filesize($filename));
fclose($handle);
$contents = chop($contents);
$shm_key = $contents;
/*DEBUG:: The Contents of the file*/
print $shm_key.br; // These are fine
# print $shm_key;
$shm_id = shmop_open($shm_key, a,0,0) or die(FATAL ERROR:: Unable
to Access Shared Memory);
/*$shm_size = shmop_size($shm_id);
DEBUG:: print (Shared Memory Block Size: . $shm_size.\n);
*/
// Now lets read the string back
$data = shmop_read($shm_id, 0, $shm_size);
if (!$data) {
echo FATAL ERROR:: Couldn't read from shared memory\n;
exit;
}
?
