title: Cannot find save handler 'redis' - Ubuntu
body: <p>I am running LAMPP on ubuntu with PHP 5.6.23. </p>
  
  <p>I decided to store my sessions in the Redis and I installed it. I also installed Predis too.</p>
  
  <p>As a searched in the web I changed my php.ini to :</p>
  
  <pre><code>session.save_handler = redis
  session.save_path = "127.0.0.1:6379"
  </code></pre>
  
  <p>But when tried create a session I am taking this error:</p>
  
  <pre><code>Warning: session_start(): Cannot find save handler 'redis' - session startup failed in /path/to/the/Untitled.php
  </code></pre>
  
  <p>You can think that there is a problem in Redis but it's not. It's working properly I can set something and I can check it with Redis-CLI :</p>
  
  <p>My redis 'set' PHP code is :</p>
  
  <pre><code>&lt;?php
  
  require "predis/autoload.php";
  $redis = new Predis\Client([
      'scheme' =&gt; 'tcp',
      'host'   =&gt; '127.0.0.1',
      'port'   =&gt; 6379,
  ]);
  $redis-&gt;set('x', '42');
  $redis-&gt;set('name','test');
  
  ?&gt;
  </code></pre>
  
  <p>Results in telnet:</p>
  
  <pre><code>Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.

  x
  </code></pre>
  
  <p>Session php code:</p>
  
  <pre><code>&lt;?php
  session_start();
  
  
  $count = isset($_SESSION['cont']) ? $_SESSION['cont'] : 1;
  
  echo $count;
  
  $_SESSION['cont'] = ++$count;
  ?&gt;
  </code></pre>
  
  <p>It must increase the number every refresh but It just displays an error.</p>
  
  <p>I re-Installed Redis again (v 3.2.3) but still no difference. </p>
  
  <p>Is there any way to solve it?</p>
  
  <p>Could LAMPP be the reason of problem?</p>
  
  <p>EDIT:</p>
  
  <p>I started to use phpredis instead of predis.</p>
