PHP notices and warnings when WP_DEBUG is enabled

[adeelq]

There are tons (3.42 MB per request) of annoying PHP notices and warnings when WP_DEBUG is enabled. Please see attached screenshot.

How to replicate?

• PHP version 8.2
• Wordpress version 6.3
• Query Monitor version 3.13.1
• Enable WP_DEBUG and WP_DEBUG_LOG in wp-config.php
• See debug.log files under wp-content directory

A Fix?

• It can be fixed easily by replacing line 34 with following
  $this->data = array_merge((array)$this->data, array('stats' => [$component => ['size' => 0, 'number_of_files' => 0, 'opcache_size' => 0]]));
• Line 36 to 48 can be removed since above will declare it one go.
