title: Get substr from string
body: <p>I have this code</p>
  
  <pre><code>&lt;?php echo $fileInfo[2] ?&gt;
  </code></pre>
  
  <p>So  <code>$fileInfo[2]</code>  outputs:</p>
  
  <pre><code>/1/VIDEO/HEY-SMITH_.mp4
  </code></pre>
  
  <p>I only want this part of the string  <code>VIDEO/HEY-SMITH_.mp4v</code>, so how do I remove <code>/1/</code> ?</p>
