title: storing incremented value in session variable and printing it
body: <p>Had googled this but maybe I'm not a good googler. My ultimate goal is to have a view more button that will read the next 6 files from a directory but before I do that I need to figure out this problem:</p>
  
  <p>at the top of my index.php i have this:</p>
  
  <pre><code>&lt;?php
    if(session_id() == '') {
    session_start();
    $_SESSION["count"] = 0;
  }
  ?&gt;
  </code></pre>
  
  <p>lower down I have this:</p>
  
  <pre><code>&lt;?php
  function album() {
     $_SESSION["count"]=$_SESSION["count"]+10;
     echo $_SESSION["count"];
  }
  ?&gt;
  </code></pre>
  
  <p>when the user clicks a button its supposed to print the session variable + 10 on each click.. so 10 20 30 40 ..ect. But it keeps printing 10, it's not updating.</p>
