Here comes an end to the years of debate for the WordPress minimum version requirement. Since only 2% of the WordPress sites run on PHP 5.2 and 20% sites run on versions PHP 5.5 or earlier, WordPress officially announced to end the support for the PHP versions 5.2 to 5.5.
The minimum required PHP version for WordPress is now PHP 5.6.2. We are indeed getting ready for another huge improvement for this popular CMS.
PHP code runs on the back-end side of the WordPress site and helps the developers to build a fully functional website. PHP thus can be said to be the backbone of the WordPress development services.
PHP runs quietly in the background and the magic you see happens on the front-end. It is the only language that WordPress relies on, which makes your site look and function in the way you expected.
Millions of people on WordPress don’t even know which version of PHP they are using currently. But recently, notifications to the users has been observed for them to upgrade to the new PHP version.
Since many site owners don’t have the technical knowledge on the PHP versions, this news is causing technical irresponsibility according to Andrey Savchenko.
The shift is not happening at a breakneck speed but had been in the discussion for long. It is considered to be the first step towards PHP version 7.
The notifications have boosted their users to update the PHP version. Yoast experimented and found that website owners upgrade the PHP version in double speed even before they were shown the notifications.
Site owners who want to remain in PHP version 5.5 or below will receive the security patches but would not be able to have the advantage of the latest WordPress version until they upgrade.
The notification also helps the site owners by providing them the information to update.
Since the latest PHP version is more efficient, it will boost the performance three to four times faster than the previous versions.
Popular platforms are on the top targets of the hackers. In order to have the latest security features for the WordPress sites, it is of utmost importance to update the PHP version. Older versions will have less support from the community when it comes to security threats.
A faster loading site along with other features get a higher rank in the search engines. They will be rewarded by the search engines.
Customers tend to leave the site which takes more time to load. If your site is more effective and is faster loading, it will retain the visitors.
These are some of the compelling reasons to update PHP today. Also, the WordPress 5.2 Beta version supports the PHP version 5.6 now.
With unsupported versions, you will not be able to upgrade to WordPress 5.2 to your site. Manually updating the WordPress version will also not be possible. WordPress also now encourages the site owners to directly update the PHP version to the recommended version PHP 7.3.
The upgrade will only be in the benefit of the site owners, improve the speed and provide better security features.
