Today, PHP is used by almost 80% of all the websites whose server-side programming language we know. Popular websites such as Slack, Etsy, Wikipedia, WordPress, Mailchimp, Canva, Indeed, Investing.com, and others are powered by PHP.
However, in the coming months, many websites that fail to upgrade to the latest version of PHP 8 will be left running unsupported versions.
PHP 7 was released back in 2015, and 68% of PHP-based websites still use PHP 7. Meanwhile, PHP 8 was released in November 2020, yet only ~ 1% of PHP-based websites currently use it!
This slow uptake of PHP 8 will become a much higher priority upgrade for organizations very soon. In fact, PHP 7 loses active support next month and loses security support in one year!
Extended support for PHP 7.4 will end on November 28, 2022. After this date, applications will continue to run; however, those applications will be out of support and at risk of security vulnerabilities that remain unpatched.
In addition, after November 28, 2022, Microsoft will no longer support PHP, and mainly Unix-based distros such as Linux will be the OS supported by future versions of PHP and continued feature, quality, and security updates.
