Very lightweight and simple plugin that displays the currently installed PHP/MySQL version in the “At a Glance” admin dashboard widget.
In the latest plugin version you can also view the current MySQL version when hovering over the PHP version text. We chose to implement it this way as you may not need to know the MySQL version as often as the PHP version, and it just adds unnecessary visual noise.
Just hover over the PHP version label to display the installed MySQL version.
Also, on some Windows based servers the returned MySQL version can be displayed with a <code>5.5.5-</code> prefix which can be a little annoying, so this is removed for convenience.
Please <a href="https://wordpress.org/support/view/plugin-reviews/display-php-version" rel="ugc">rate</a> this Plugin if you find it useful. It only takes a moment but it’s very much appreciated. 🙂
And here’s how you can <a href='https://www.paypal.com/biz/fund?id=6EW7V4MWJP8ZE' rel="nofollow ugc">help support</a> our open source work. We couldn’t do this without you!

Plugin Compatibility Checker

very helpful to check our plugin compatibility


The plugin checks in free version up to php 8.0+ compatibility. Who needs to know if a plugin is compatible with an obsolete version of php ?


A joke ?


The free version gave me a basic idea, but the paid version was way more useful. It caught PHP issues that I wouldn’t have noticed before updating. Glad I upgraded because it saved me time fixing errors later. Definitely more helpful when running sites on newer PHP versions.


Actually prevented a break on upgrade

Scan and check your plugins for PHP and WordPress compatibility. Requires a $1/month Portal subscription to obtain a license key.
