[Q] How to use xdebug_enable() parameter

From Troubleshooting Techniques

Hello, members.

Could you tell me how to use xdebug_enable parameter?
Do I need an extra module or something?

When I append the following config into config.php, It shows a blank(white) page.
And PHPlist doesn’t work as I expected.

define('VERBOSE', true);

I got the following error.

Uncaught Error: Call to undefined function xdebug_enable() in /var/www/html/lists/config/config.php:123
Stack trace:
#0 /var/www/html/lists/admin/index.php(74): include()
#1 {main}
  thrown in /var/www/html/lists/config/config.php on line 123

Best regards.
