Re: [PHP] Users Online?
Why all this mess for such a simple thing? All you need is to allocate the last activity timestamp with userid in the users table, add 'last_activity' column to the users table then update it with every page load at the administration panel. Then all you need to do in order to print out the current logged in users is to SELECT `username` FROM `users` WHERE `last_activity` > time() - 60*15 60*15 means that users which had an activity during the last 15 minutes will be shown as logged in ;) This is the way I would do that if you have no session handling system.

[PHP] mirroring website
Hey I have the following issue! I want to develop my website on my local machine, and then upload the entire developed site to a production server. What is the best strategy to do that? I have been looking at a php mirroring script but that was about 5 years old! Is'nt there a better/newer approach? By the way...

Re: [PHP] mirroring website
Create 2 different configuration files, load the appropriate one after checking whether $_ENV['dev'] is set to 1 or 0 then all you have to do is to set the environment variable 'dev' to 1 or 0 through .htaccess file. After setting this up all you have to do is to rewrite the files whenever you want to update the files in the production server or vice versa.

And, if you don't have ssh access to the web server -- but rather, just ftp -- there's `ftpsync` which I use. When Googling for `ftpsync` , ignore the windo$ hits. There's a name collison there.

[PHP] Passing Values between C App and PHP
Hi, I've recently written an eMail regarding I2C and PHP - since I haven't found a nice solution yet, I'm considering writting the I2C part (opening device, writing, reading,...) in C (that's simple) and to recieve (and returning) the values through PHP and Javascript. E.g. Website (PHP/Javascript) -> set a new motorspeed -> PHP passes the new speed to C Application -> C AP opens and writes the new speed onto the I2C Bus -> Motor executes -> returns ack -> Is this somehow, and not complicated possible?

[PHP] Problems with APC, possible cache-corruption?
(Resend from around 1 week ago, because of no responses) Hi All, Over the weekend I setup a test of APC intending to benchmark a Moodle installation with various APC settings to see how well I could get it to perform. I successfully installed Moodle 1.9 and 2.0 under Apache 2.2.3 (installed via apt on Ubuntu 9.04), and with PHP 5.2.9 compiled from source. I should note, that Ubuntu had an older version of PHP installed from apt with Suhosin hardened PHP built in. Moodle 2.0 required at least PHP 5.2.8, so I uninstalled the original PHP module before compiling and installing the 5.2.9. No issues there; PHP worked well and performance was (mostly) acceptable. Progressed onto installing APC, firstly by downloading the APC 3.1.2 source from PECL and following the usual 'phpize, configure, make, make install' process which worked as expected, stop and start Apache and APC was present in my phpinfo();. I started with the reccomended PHP config exept with error_display turned on and E_ALL | E_STRICT enabled, and also the reccomended APC config also. I copied the 'apc.php' from the source tree to my webroot and changed the password as suggested. The issue arose when I attempted to benchmark my Moodle install with 'ab' (I realise it only downloads the single page, but it's good enough for what I need for now though) and the result was no different to before I had installed APC. View the apc.php page, and the only page cached is apc.php itself.. Certainly not what I've witnessed in the past. Then what would happen was if I viewed my seperate info.php page containing simply the opening PHP tag and a single line with phpinfo(); in the file - the cache would appear to reset, and it would firstly not load the info.php into the cache, it would reset the counter on the apc.php file back to 0. Through all of this, there was no errors displayed on the screen and no errors listed in the Apache error log either. Increased the Apache log level up to Debug, and no related information was displayed. Moodle itself worked as expected with no errors, and on a seperate RHEL installation I have Moodle working with APC and it is caching all it's files as expected. At this point, I thought it may be an issue with the module I compiled myself. I backed up the module, and allowed PECL to install the module, it installed 3.0.19. Restarted Apache and verified the version was as PECL had built and installed. This had no effect, and yeilded the same behaviour. I'm stumped as to what the issue could be, however I did see this issue of APC not caching files on an installation of Red Hat Enterprise Linux in the past - however at the time we assumed it was an issue with the framework we were using and due to time constraints simply ran without APC and didn't investigate further. Has anyone seen this issue in the past and perhaps even rectified it? Any information would be appreciated.

Well, index.html wouldn't be cached because it's not parsed by the PHP engine. But yes, if it were index.php for example each compiled PHP file is then cached in the opcode cache - include files and everything. This is how it works on every other APC installation i've tried :) This installation is not doing that, even though this is the default behaviour. > if apc has support for output caching, ive not yet used it so im not sure how > much i could help there (sort of sounds like youre shooting for output > caching the way you describe things above). No, i'm not looking for output caching. Apologies if my original email was poorly worded. > maybe you could dump out your ini settings for apc and share them here? No need. they're all default as reccomended by PHP and APC. Thanks, James -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Problems with APC, possible cache-corruption?
Can you do a phpinfo(); and tell us the value of the setting apc.filters (or every apc.* if you can)? Just curious, but I've seen apps set that setting to avoid APC opcode caching.

Though I'm not sure that would be the case as APC is caching all Moodle files on my development server here. That being said I'll grep the codebase anyway to see if it's setting any filters.
