WordPress Suggestions

PHP needs to be up to date regularly, identical to WordPress core, themes, and plugins.

With PHP, every model receives assist for 2 years after its preliminary launch, then there’s a interval of one other yr the place solely important safety updates are launched, as wanted.

After this three yr interval, that model of PHP is now not supported.

As of July 2021, the present really helpful PHP model for WordPress is 7.4 or better.

High quality internet hosting suppliers will usually require you to make use of the WP really helpful model of PHP with a purpose to use their servers, and can show you how to modify your website to make sure that the newest model of PHP is not going to break it.

This implies greater than one-third (37.2%) of WordPress websites are at present operating variations of PHP which can be now not actively supported.
