I want to display the notice and warning logs on the web.

I would like to display notices and warning logs on the web in a development environment using CakePHP, but it doesn't work.

Run Environment
CakePHP 2.2
PHP 5.3

confirmed, executed
·Check with phpinfo
The display_errors item is off for Local Value and on for Master Value.

·php.ini
error_reporting=E_ALL
display_errors=On
Missing comment in the above settings

·httpd.conf
php_flag display_errors on
If you put this in the top or bottom of the conf file, no errors will be displayed

·htaccess file
I checked htaccess in the CakePHP source, but there was no description to hide PHP errors, and php_flag display_errors on did not change.

·CakePHP side
Setting the core.php DEBUG mode to 1 to 2 to 3 does not show up on the screen.
The log files under the log folder contain notices and warnings, but I want to be able to see them on the screen...

·Description in PHP file
ini_set('display_errors', 'On');
Even if you write this at the beginning of the PHP file, it does not appear on the screen.

I have checked so far, but even if it is recorded in the log file, there is no error on the screen.
I'm stuck, but I wonder if there are any other possible causes...
Thank you for your cooperation.
