Deprecated warnings filling up PHP log

[ad_1]

Anyone have a way to stop wordpress from filling up my log files with PHP deprecated warnings? I understand WP is not officially supported on PHP 8.1 and therefore these messages are expected at this time. I would like for them to stop filling up my logs.

My production PHP error\_reporting is:

`error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR|E_PARSE`

My wordpress wp-config.php has:

$wp_debug = false;
if ($wp_debug) {
ini_set(‘error_reporting’, (E_ALL & ~E_NOTICE | E_STRICT));
ini_set(‘display_errors’, ‘On’);
} else {
ini_set(‘error_reporting’, (E_ALL & ~E_NOTICE & ~E_DEPRECATED));
ini_set(‘display_errors’, ‘Off’);
}

Yet my log file fills up with stuff like:

(which are all core WP files)
