Class 'App\Controller\Debugger' not found error with cakephp ver3

问题

I am using cakephp 3.0.2. I tried to use Debugger::dump($date_taken_year); and encountered the error Error: Class 'App\Controller\Debugger' not found. If I remove the line that uses Debugger::dump(), the error disappears and the controller function runs smoothly.

I have checked that inside app.php, I have this line 'debug' => true,. Do I have to do anything else to use Debugger class? I had no problems when using cakephp ver2.x

回答1:

It seems, you only forgot to import namespace, proper use would be

use Cake\Error\Debugger;
// ...
Debugger::dump($date_taken_year);
