To install new php modules on your Ubuntu/Debian, all you need to type in is:
sudo apt-get install php5-curl php5-gd php5-mcrypt
If you need to check what is installed php-wise you can:
dpkg --list | grep php
this could look like this:
:~# dpkg --list | grep php ii libapache2-mod-php5 5.5.9+dfsg-1ubuntu4.7 amd64 server-side, HTML-embedded scripting language (Apache 2 module) ii php5 5.5.9+dfsg-1ubuntu4.7 all server-side, HTML-embedded scripting language (metapackage) ii php5-cli 5.5.9+dfsg-1ubuntu4.7 amd64 command-line interpreter for the php5 scripting language ii php5-common 5.5.9+dfsg-1ubuntu4.7 amd64 Common files for packages built from the php5 source ii php5-json 1.3.2-2build1 amd64 JSON module for php5 ii php5-mysql 5.5.9+dfsg-1ubuntu4.7 amd64 MySQL module for php5 ii php5-readline 5.5.9+dfsg-1ubuntu4.7 amd64 Readline module for php5
If you want to add the gd library for example, try: php5enmod gd
root@blubb:~# php5enmod gd WARNING: Module gd ini file doesn't exist under /etc/php5/mods-available
In this case, it didn’t work, so let us install the library using ” apt-get install php5-gd”. The output may look like this:
root@blubb:~# sudo apt-get install php5-gd Reading package lists... Done Building dependency tree Reading state information...

Now you may enable the phpmodule and restart the apache:
root@blubb:~# php5enmod gd root@blubb:~# service apache2 restart * Restarting web server apache2
i use a small php test.php script to have a look at the php configuration in a well formated, it looks like this:
<?php
echo phpinfo();
?>put it in your webspace and check the output by typing in: www.yourdomain.de/test.php
The installed and enmoded php extension should now be available.
good luck and have fun!
