PHP Compatibility Scanner helps you assess whether your site’s code (plugins and themes) is likely to run on newer versions of PHP. It performs static analysis using PHP_CodeSniffer and the PHPCompatibilityWP ruleset to flag code patterns that are incompatible with the selected target PHP version.
What the plugin does (at a glance): 
– Compares your current runtime PHP (baseline) to a selected target PHP version (8.0–8.4). 
– Scans plugins and themes, then highlights only the new issues that would appear on the target version (the “delta”). 
– Shows results in a clear report on the Tools screen and adds small badges on the Plugins list screen. 
– Lets you pause, resume, or stop a running scan.
Important limitations of static analysis: 
– Static analysis can miss issues in dynamic code paths and can generate false positives. Treat results as guidance, not guarantees. Always test site functionality on a staging environment before upgrading PHP in production.

A valuable piece of information is missing on the plugins management page in WordPress. The WordPress version the plugin has been tested up to.
This plugin fixes that, it adds a new column on the plugins page which shows the version of WordPress that your plugins have been tested up to ( according to the plugin author ). It also applies colors to spot potentially problematic plugins.
The following colors are used:
<ul>
<li>Bold Green – Tested on the exact same version you are using. ( No issues )</li>
<li>Green – Tested on the latest major release. ( Issues highly unlikely )</li>
<li>Yellow – Tested on the latest major release but not in the last 4 or more patch releases. ( Issues unlikely )</li>
<li>Red – Not tested on the latest major release. ( Issues are possible )</li>
</ul>
