Minimum Recommended WordPress PHP Is 7.4
WordPress also works with older PHP versions, so you can still use them if necessary. However, it’s always best to use the latest version of PHP for security and performance reasons.
When it comes to PHP versions, it’s important to understand the concept of end-of-life for PHP versions. End-of-life refers to the point at which a particular version of PHP is no longer supported with updates or security fixes. This support ends because newer versions of PHP are available. Keeping up with these updates and transitions to more recent versions is essential to ensure your website or application remains secure and functional. Failure to do so can lead to vulnerabilities and potential issues in the future.
Two PHP Pre-End-Of-Life Support Phases
Each PHP version is fully supported for two years from its initial release date. During this phase, PHP versions receive regular patch releases that contain bug fixes and security patches. These updates are typically released monthly unless there are no bugs or security issues.
After two years of active support, PHP versions are supported for an additional year for critical security issues only. Releases during this phase are on an as-needed basis, depending on the number of problems reported.
Once the three years of support are completed, the PHP version reaches its end of life and is no longer supported.

WordPress Theme May Require 7.4 or Higher
If you’re looking to optimize your WordPress theme, it’s worth noting that some newer themes may require PHP 7.4 or higher for optimal performance, security, and features. Themes incorporating modern coding practices and leveraging the latest PHP features may even recommend or work better with PHP 7.4 or higher. This aligns with a broader trend within the WordPress and PHP communities, as developers increasingly recognize the benefits of using the latest PHP versions.
To determine which WordPress themes require PHP 7.4 or greater, you can check the theme’s documentation or contact the developer for more information. It’s important to ensure that your website uses the recommended minimum PHP version for WordPress to ensure optimal security and performance.
To check if your hosting PHP version is compatible with your WordPress theme, you can follow these steps:
- Check Theme Documentation: Start by checking the theme’s official documentation. Many themes mention the recommended or minimum PHP version in their documentation. Look for a “Requirements” or “System Requirements” section.
- Contact Theme Support: If you need help finding the PHP version information in the documentation, contact the theme’s support team. They should provide the required PHP version for the theme to function correctly.
- WordPress Theme Repository: If you downloaded the theme from the official WordPress theme repository, you might find PHP compatibility information in the theme’s description or other details.
- Review PHP Features: Themes that use newer PHP features and coding practices might be more likely to require a higher PHP version. If your theme uses features introduced in PHP 7.4 or later, it indicates that your hosting needs to support at least that version.
- Compatibility Checker Plugin: Plugins are available in the WordPress plugin repository to help you check the compatibility of your theme and plugins with your hosting environment. One such plugin is “PHP Compatibility Checker.” Install and activate it, and it will scan your theme and plugins to provide information about their compatibility with the PHP version you’re running.
- Contact Hosting Support: If you have figured out the required PHP version for your theme and need help determining which version your hosting is using, contact your hosting support. They can provide information about the PHP version on your server.
- Update PHP Version: If your hosting’s PHP version is not compatible with your theme and you want to use that theme, consider updating your hosting’s PHP version. Most hosting providers can change the PHP version through their control panel or dashboard.

- Compatibility problems: As other technologies evolve, older versions of PHP may not be compatible with newer software and hardware. Incompatibilities can lead to errors and other issues when running your website or application.
- Lack of support: As PHP versions become outdated, the community may no longer support them. This means that you may not be able to get help if you run into issues or need to troubleshoot problems.
