What is PHP?
PHP (a recursive acronym for PHP: Hypertext Preprocessor) is a server-side programming language. Its main job is to generate dynamic web pages and interactive web applications. Every WordPress site uses PHP as its base language.
When does it make sense to change the PHP version?
Like WordPress, PHP keeps evolving —with performance improvements, new features and security patches. Updating your version may be necessary or beneficial when:
- WordPress requires a newer PHP version to work properly.
- Your current PHP version is outdated and poses a security risk.
- A newer PHP version offers performance or stability improvements you want.
Which PHP version should you use?
In most cases, use the version your hosting provider recommends. If you don't have a specific reason to use a different one, follow the system's recommendation —at DISSAU (and other leading providers) the currently recommended version is PHP 8.3.
Why run the latest stable version
- Better loading and startup performance.
- Greater compatibility with modern WordPress plugins and themes.
- Built-in security improvements.
- Active support and guaranteed updates.
