PHP autoload looking in current php file

Question

In file: deckclass.php , with DOCROOT set to /var/www/Proj/application/controllers

getting error: Fatal error: Class 'Cardclass' not found in /var/www/Proj/application/controllers/deckclass.php on line 38

Why is it searching current php file and not DOCROOT folder?

function __autoload($class_name) 
{
  //class directories
  $filename = DOCROOT .strtolower($class_name) . ".php";
  if ( file_exists($filename) )
  {
    require_once ($filename);
  }
  else {
    throw new Exception("Unable to load $class_name.");
  }
}

$card = new Cardclass();

Do you have any php file named as Cardclass in your controller folder? — prashant thakre

I deleted my answer as it was not a solution, I suppose for some reason the autoload method is not registered, otherwise you would be able to print the filename, unfortunately I don't know why. — Ende Neu

You can use define('ROOT', dirname(__FILE__)); and define('DS', DIRECTORY_SEPARATOR);

Tip

spl_autoload_register() provides a more flexible alternative for autoloading classes. For this reason, using __autoload() is discouraged and may be deprecated or removed in the future.

So do code should look like this:

     <?php
        define('DS', DIRECTORY_SEPARATOR);
        define('ROOT', dirname(__FILE__)); //This is full path
        spl_autoload_register('Autoloader'); //You can use annonymous function here
        function Autoloader($class_name){
          $filename = ROOT.DS.strtolower($class_name).".php";
          var_dump($filename);
          if(file_exists($filename)){
            require_once ($filename);
          }else{
            throw new Exception("Unable to load ".$class_name."in".$filename);
          }
        }

        $card = new Cardclass();

With __autoload:

<?php
        define('DS', DIRECTORY_SEPARATOR);
        define('ROOT', dirname(__FILE__)); //This is full path
        function __autoload($class_name){
          $filename = ROOT.DS.strtolower($class_name).".php";
          var_dump($filename);
          if(strpos($class, 'CI_') !== 0) {

             if(file_exists($filename)){
               require_once ($filename);
            }else{
               throw new Exception("Unable to load ".$class_name."in".$filename);
            }
          }
        }

        $card = new Cardclass();
