Cool idea! I’d genuinely never thought of “only show to my IP” type of debug rules 🙂

You can also, in the wp-config file, reduce the scope of the debug information with a test, which is based on your IP address (to be replaced by your current address of course).

Something like that:

if (“123.45.67.89” === $_SERVER[“REMOTE_ADDR”]) {
define( ‘WP_DEBUG’, true );
} else {
define( ‘WP_DEBUG’, false );
}

This reduces harmful displays on a production site (while still using the other methods mentioned)
