php.ini-s packaged : development and production
php.ini-development and php.ini-production, which come with the PHP 5.3 package, are really just examples of recommended settings. You should review the settings and make sure that they apply to your use and copy them to the regular php.ini file location. On my Ubuntu 10.04.1 LTS (lucid) server, here’s where I find mine:
# locate php.ini-development
/usr/share/doc/php5-common/examples/php.ini-development
The alternative example, php.ini-production, is in the same directory.

Enable mod_rewrite

mod_rewrite?

Install - enable mcrypt
Also on Ubuntu, make sure you actually have php5-mcrypt installed. You can install it with:
sudo apt-get install php5-mcrypt
If you get any errors, you may need to enable the 'universe' repository, explained here:
https://help.ubuntu.com/community/Repositories/Ubuntu

Unable to lock the administration directory
After execute command :
sudo apt-get install php5-mcrypt
Error message appear :
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
Answer :
As per the other answers there is a package management app holding the lock. When unsure do not manually remove the lock, first run:
sudo fuser -cuk /var/lib/dpkg/lock; sudo rm -f /var/lib/dpkg/lock
This will kill any processes opening the file before removing it.

Install PEAR
PEAR is PHP’s equivalent of
Perl’s CPAN. It offers hundreds of ready-to-use code modules that can make projects go much more quickly than having to hand code everything. However, it never seems like PEAR is easy to get running.
Installing the Needed Software
In Ubuntu, installing the following packages will quickly get you started with PEAR: php5-cli, php5-dev, and php-pear.
Make sure that you read the next section about problems with using PEAR to install PEAR packages if you are running 9.10, Karmic Kaola.
Here’s an example of how to quickly install those packages from the terminal.
$ sudo apt-get install php5-cli php5-dev php-pear

XSL with PHP in Ubuntu
XSL support in php5 is deactivated by default. Go to Synaptic Package Manager and search for php5-xsl. Mark the package for installation, apply the changes and once it’s finished, don’t forget to restart the server!
sudo /usr/sbin/apache2 -k restart
More XSL stories later on… time to experiment :)
