PHP Versions: Why Updating Matters
March 2, 2026
What is PHP?
PHP is the programming language many websites and CMS platforms, like WordPress, are written in.
Why Update PHP?
Security
Older PHP versions no longer receive security updates and are vulnerable to hackers.
Speed
Newer PHP versions are significantly faster. PHP 8 is up to 3x faster than PHP 5.6.
Compatibility
New plugins and themes often require recent PHP versions.
Choosing a PHP Version
Always use the newest stable PHP version that your software supports.
Before You Update
Test your website on a staging environment before updating PHP. Some older plugins don't work with newer PHP versions.
