Observation on Unused Global Variables in WordPress Core PHP Files

[viralsampat]

Hello Team,

I have reviewed the WordPress core PHP files and noticed that some global variables are referenced in the comments but are not explicitly defined in the code itself.

So, I think that if these variables are not being used anywhere, they should be removed from the list to avoid confusion and keep the codebase clean.

Files:

---

wp-admin/includes/plugin.php
wp-includes/rss.php
wp-includes/update.php

Please review it and share your feedback.

Thanks,

I have checked above mentioned issue and resolved it. Here, I have added my patch.

Both wp-admin/includes/plugin.php and wp-includes/rss.php look OK to me.

wp-includes/update.php uses wp_get_wp_version() since r58813, so some references to the $wp_version global could be removed.

@viralsampat $GLOBALS['wp_version'] is used in plugin.php and rss.php so those should stay.

In 60493:

Docs: remove global references to $wp_version that are no longer accurate.

This commit cleans up a few global $wp_version doc-block entries for functions that switched to using wp_get_wp_version() in 6.7.

Follow up to [58848], [59192].

Props viralsampat.

Fixes #63732.
