Bumpcheck tells you which plugins and themes would stop working, before the switch. Pick a PHP version from 8.0 to 8.6 and run the scan. Each plugin and theme gets one of three results: * **Breaks**: it calls something that the chosen PHP version removed or no longer ships. The page shows the file, the line and what to use instead. * **Works, uses deprecated code**: it runs, but PHP will log deprecation notices. * **Ready**: nothing found. #### What makes it different * **It reads the files on your server.** Premium plugins, custom plugins and your own theme are checked like everything else. * **Nothing leaves your site.** No account, no outside service, no data sent. * **It covers PHP 8.0, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6.** * **It does not time out.** The scan runs in short steps. In our test, 21,000 files took 13 seconds. * **It knows about old fallback code.** Many plugins keep a branch for ancient PHP versions that never runs on your site. Those lines are listed apart and do not count against the plugin. #### What it checks Removed and deprecated functions, constants and INI settings. Array offsets with curly braces. The `(unset)` and `(real)` casts. Constructors named after their class.`" ${var}"` in strings. Missing return types on `ArrayAccess`, `Iterator`, `Countable` and `JsonSerializable` methods. `Serializable` without `__serialize()`. Parameters that are nullable only through a null default. Required parameters after optional ones. `get_class()` without an argument. A third argument to `define()`. Deprecated` mb_convert_encoding()` encodings. Functions of the IMAP, pspell and OCI8 extensions, which PHP 8.4 no longer ships. #### What it cannot check The scan reads code and does not run it. Problems that depend on values at run time are out of reach, for example passing `null` to a function that needs a string, or properties created on the fly (deprecated in PHP 8.2). A clean result means nothing known was found. Test on a staging copy before you switch a busy site. #### Bumpcheck Pro A separate add-on adds a weekly or daily scan with the result by email, CSV and JSON export, and a WP-CLI command.

Deleting the plugin removes that result. ### Does it check WordPress itself? No. WordPress core supports the PHP versions listed on wordpress.org. Bumpcheck checks what you added: plugins, must-use plugins and themes. ### A plugin shows “already true on my PHP version”. What does that mean? The code uses something that was removed in a PHP version you already run. If that code ran, it would fail today. It is almost always an old fallback branch, so it does not count as a result of the upgrade. ### Is a “Ready” result a guarantee? No. See “What it cannot check”. ### A plugin breaks because PHP 8.4 no longer ships the IMAP extension. Is that certain? PHP 8.4 moved the IMAP, pspell and OCI8 extensions out of PHP. A host can still install them separately. Bumpcheck cannot see what your host will install after the upgrade, so ask your host. If the extension stays available, that plugin keeps working. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Bumpcheck – PHP 8 Compatibility Check” is open source software.
