title: Replace double backslash in linux php application
body: <p>I have a rather naive question. In wamp environment I used composer in order to input some library and I use it like this:</p>
  
  <pre><code>use Hpar\PrestashopBridge\PrestashopBridge;
  </code></pre>
  
  <p>However in linux environment I get the following error:</p>
  
  <blockquote>
    <p>mod_fcgid: stderr: PHP Fatal error: Call to undefined method
    Hpar\PrestashopBridge\PrestashopBridge::redirect() in
    /var/www/vhosts/example.com/</p>
  </blockquote>
  
  <p>(it replaces the backslash with double backslash). How can I solve it? </p>
