php-errors.log not working!

Hello,

I created a log file “php-errors.log”

then I edited the “wp-config.php file by adding:

ini_set('log_errors', 'On');
ini_set('error_log', '/****/****/php-errors.log');

“****=the path”

but didn’t get any error logs..

So I edited the “wp-config.php by adding:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors', 0);

and got the logs, any idea why it didn’t work with php-errors.log?
