title: Easiest way to install Mongodb PHP extension in Ubuntu 13.10 (saucy)?
body: <p>I'm using Ubuntu 13.10 (saucy salamander) and I was hoping that <code>sudo apt-get install php5-mongo</code> would be enough to get the mongodb database driver installed.</p>
  
  <p>No such luck though. I'm using php5-fpm, so firstly I found I also needed to do <code>php5enmod mongo</code> but even with that, I get a error:</p>
  
  <pre><code>include(MongoClient.php): failed to open stream: No such file or directory
  </code></pre>
  
  <p>Instead, to install I have to do the following (which uses a lot more disk space):</p>
  
  <pre><code> sudo apt-get install php5-dev make php-pear
   sudo pecl install mongo
   sudo echo "extension=mongo.so" | tee /etc/php5/mods-available/mongo.ini
  </code></pre>
  
  <p>My question is why isn't  <code>sudo apt-get install php5-mongo</code> enough? Is it a problem with the Ubuntu repo? How can I look into the ubuntu repositories and find what version it uses or why <code>MongoClient.php</code> isn't included. I'm using the "<code>ubuntu:saucy</code>" docker image as my base and it includes universe by default I think.</p>
