body: <p>I have successfully uploaded my image to a folder and rename to serial number (eg:12345.jpg).</p>
  
  <p>It is possible to rename the file after being upload to folder??</p>
  
  <p>I am getting:</p>
  
  <p>Warning: rename(/ABT1/uploads/Bicycle/test.jpg,/ABT1/uploads/Bicycle/test2.jpg): The system cannot find the path specified. (code: 3) in C:\xampp\htdocs\xampp\bicycleTheft\ABT1\test2.php on line 4</p>
  
  <p>I have tried:</p>
  
  <pre><code>if(isset($_POST['btn-update']))
  {
      rename("/uploads/Bicycle/test.jpg", "/uploads/Bicycle/test2.jpg");
  
  } 
  </code></pre>
