    I just upgraded our servers from PHP 7.4 to PHP 8.2 and our frontend and admin screens are working okay, no noisy warnings, but when I use the wp-cli provided by my host (Cloudways) I’m getting lots of warnings. Here is a portion of the warnings I’m getting when I run ANY wp-cli command. You’ll notice that basically every constant that is defined my wp-config.php gets two lines of warnings.

    myuser@333333 ~/public_html $ wp eval --skip-themes "var_dump(WP_DEBUG);"

    For clarity, these warnings are not emitted when I have the server configured to use PHP 7.4, it only started when I upgraded the server to PHP 8.2.

    I’ve definitively narrowed the noisy offending plugin down to wp-security-hardening by using the wp-cli’s “–skip-plugins” option, so I get these warnings every time until I run it with –skip-plugins=wp-security-hardening.

    In terms of environment that I’m running, my host is Cloudways and the WP-CLI executable is provided by the hosting provider and the version of it is WP-CLI 2.9.0.

    I believe I have partially figured out what is going on, the /modules/hooks.php file has this code at the top:

    require_once(ABSPATH."/wp-includes/pluggable.php");
    require_once(ABSPATH."/wp-load.php");

    When I comment those lines out the warnings I’m complaining about go away.

    Does anybody know why the plugin needs to require these two files here? It seems like it works without these lines.
