What is PHP, and how does it affect a WordPress website?
PHP is the engine that runs your WordPress website. To keep your engine running smoothly, you must keep your engine (PHP) running smoothly and up to date.
Older versions of PHP are more likely to have security vulnerabilities, which hackers could (and eventually will if you don’t update) exploit. Additionally, older versions of PHP may not support newer features and functionality, which could limit the capabilities of your website and cause it to break.
Once a PHP version reaches the end of its life, it no longer receives security updates. This leaves your website vulnerable to hacking attempts and other security breaches. Cybercriminals often target websites with outdated software because they know these sites are more susceptible to attack.
What happens if you don’t update WordPress?
Not updating WordPress leaves your site vulnerable to hackers and viruses. Your website can be taken over, malware added, and you could lose your site.
Performance and Speed
Each new PHP version brings performance enhancements and optimizations, such as improved memory usage and faster processing speeds. This results in quicker page load times for visitors and a more efficient website overall.
Compatibility:
WordPress, themes, and plugins are continuously updated to work with the latest PHP versions. Running an older PHP version can lead to compatibility issues, errors, or even broken functionalities with newer WordPress components.
New Features and Improvements:
Newer PHP versions introduce new features, functions, and improvements that can be leveraged by WordPress and its extensions to offer better functionality and user experiences.
Active Support:
PHP versions have a lifecycle, and older versions eventually reach end-of-life status, meaning they no longer receive active support or security patches. Updating ensures the website is running on a supported version that receives ongoing maintenance and security updates.
