MyClass.php in the components folder

      public function get_my_info() {
      $value = '1';
          return $value;
     }

    }

Declare in the config folder

'components'=>array(

        'user'=>array(
            // enable cookie-based authentication
            'allowAutoLogin'=>true,
        ),

                'myClass' => array(
                    'class' => 'ext.components.MyClass',
                ),

And use in the view file

<?php  
        $myInfo = Yii::app()->myClass->get_my_info(); 
        echo $myInfo;

?>

Check your file permissions. Update it to 755 and then check. I know its a late comment, but it may help some one else — Awais Mustafa, May 16 '19 at 18:07

Have you put the file in correct component directory?. As per your alias the path should be /protected/extensions/components/MyClass.php
