title: fopen file in appdata folder (wamp)
body: <p>I have some csv file in this path:</p>
  
  <pre><code>C:\Users\myusername\AppData\Roaming\some_file.csv
  </code></pre>
  
  <p>I want to open this file by <strong><code>fopen()</code></strong> from my www dir (wamp).
  Here my try:</p>
  
  <pre><code>$my_file = fopen('C:\Users\myusername\AppData\Roaming\some_file.csv', 'r');
  </code></pre>
  
  <p>Here what I get:</p>
  
  <blockquote>
  <pre><code>"failed to open stream: No such file or directory"
  </code></pre>
  </blockquote>
