title: failed to open stream: No such file or directory in PHP
body: <p>I have  php files in My includes folder like this,<br>
  <code>newclass.int.php</code></p>
  
  <pre><code>&lt;?php
  class NewClass extends ParentClass {
      }
  ?&gt;
  </code></pre>
  
  <p><code>parentclass.int.php</code></p>
  
  <pre><code>&lt;?php
  
  class ParentClass{
      public $name = "Hey There!";
  }
  ?&gt;
  </code></pre>
  
  <p>and <code>index.php</code> like this</p>
  
  <pre><code>&lt;?php
  include 'includes/parentclass.int.php';
  include 'includes/newclass.int.php';
  $object = new NewClass;
  ?&gt;
  
  
  &lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;oop php&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;?php
  echo $object-&gt;name;
  ?&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
