Last but one PHP release was a SECURITY FIX
PHP 7.1.23 is now available. It is a BUG FIX, but ...
PHP 7.1.22 was a SECURITY FIX.
Are YOU checking which version and release of PHP is being used by your Joomla! website?
We strongly recommend that you periodically check which release is being provided by your hosting provider for the PHP version used by your website.
Always request that they provide the latest available security release.
Do not settle for anything earlier than PHP 7.1 if you are using the latest available release of Joomla! CMS (recommended).
We tell you how to check which version & release of PHP is being used by your Joomla! website in our JOOMLERS.UK User Guide.
How to check which PHP version is being used
You can quickly check the version of PHP after signing into your website's control panel.
Select System > System Information from the menu at the top of the control panel screen.
If when you check you see a version of PHP earlier than PHP 7.1, contact your hosting provider and request an upgrade.
Reason: your website will perform better and it will be more secure - especially if it is using the latest release!
Note: Joomla! 3.7 and earlier will not work with PHP 7.1.
Always use the latest available release of Joomla! CMS.
