Set WordPress to Enable Error Logging but Move Error Log Outside of /public_html/

The snippet below is for pasting into wp-config.php:

• to enable error logging into file debug.log, but move it outside of public_html
• to disable showing errors (you can switch comment below to allow display of errors)

// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );

// Enable Debug logging to the debug.log file
//define( 'WP_DEBUG_LOG', true );
ini_set( 'log_errors', 1 );
ini_set( 'error_log',  __DIR__. '/../debug.log' );

// Disable display of errors and warnings 
//define( 'WP_DEBUG_DISPLAY', true );
//@ini_set( 'display_errors', E_ALL );
define( 'WP_DEBUG_DISPLAY', false );

// Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
define( 'SCRIPT_DEBUG', true );
