(Read the update below before starting to copy-paste) To install Xhprof on PHP5.4 on Ubuntu (assuming you’ve already got PHP5.4 from Andrej or somewhere safe) in order to measure the load of Chamilo 1.10 dev (you need to have a mercurial clone, otherwise the “tests” directory will not exist), follow this procedure (all lines prefixed […]
If you happen to develop large sites in Drupal, you might fall upon a case like this one, where different servers (namely at least one reverse proxy and one web server) interact, causing a series of chain reactions every time you change something. It might be frustrating, at times, to try and boost a coordinated […]
Just as a self reminder, and because I don’t fancy too much looking into the Drupal core for debugging, here is a short explanation of how the Drupal 7 bootstrap mechanism works. First of all, a bootstrap mechanism is a mechanism by which you work progressively your way through the full loading of a system, […]
Just as a self reminder, this blog post explains why php-cgi might hang/stop silently when your load increases, and how to fix it, where it explains (in short) that fast-cgi should have the parameter PHP_FCGI_MAX_REQUESTS should equal 1000 or more (this can be done in /etc/default/php-fastcgi on my Ubuntu server). Also worth a look […]
Due to a licensing issue, the PHP bindings for Xapian were removed from Debian Squeeze. See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=513796 for more information about this. Though, it is not really hard to build your own package from source. Here is how: sudo apt-get build-dep xapian-bindings sudo apt-get install php5-dev php5-cli apt-get source xapian-bindings cd xapian-bindings-1.2.* rm debian/control env […]
Edit: as of July 2014, there is a recent article discussing the use of php5-memcache instead of php5-memcache to store sessions on this blog. There are many posts around on the web about using memcached to store sessions data on high-availability servers, but few actually cover the whole topic and there are some elements that […]
For some reason I find myself having to work with CentOS a lot these days. I hate to say I hate something, but I can’t help saying I don’t like CentOS at all. Its packaging system is just so inconsistent and error prone I can’t understand how this could ever be considered an appropriate server […]
This command is to be improved progressively… sudo apt-get install apache2 libapache2-mod-php5 mysql-server mysql-client php5-mysql php5-xcache php5-gd php5-xdebug screen phpmyadmin php5-imagick mercurial git php-pear php5-dev
There’s a short but great article about setting up PHPEclipse with Xdebug here: http://bogdan-albei.blogspot.com/2010/06/php-remote-debugging-with-xdebug-and.html I really don’t want to forget this one!
I’ve been trying to find the kind of PHP library that allows you to quick-generate an HTML form a basic XML structure. Apparently there is no such thing, so here you can find some code that will help you do that (you still have to build the form tags from outside the function). This code […]
Update 2010-12-21: A really serious security flaw has been detected in Exim 4 < 0.70. Please make sure your version is secure: https://forum.bytemark.co.uk/comments.php?DiscussionID=2701 If you’re a developer who works with Ubuntu or Debian, or at least with PHP and Apache, you will have the problem at some point that you want to send e-mails from […]
Let’s say you want to install Chamilo on your netbook for a demo… Because Apache uses a lot of memory (and so does MySQL), it is generally considered a good practice to try and use something a bit lighter for your web server This procedure might also work, with a few minor alterations, for OLPC’s […]
