What Is the Lowest PHP Version I Need to Have for WordPress?

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

Active Support

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.

Security Support

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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.

How Outdated PHP Impacts WordPress Websites

WordPress relies heavily on PHP, and it plays a pivotal role in shaping every WordPress website. PHP is not only a fundamental component of the backend but also significantly influences the frontend of your WordPress interface and pages. It empowers website development by not only being present in page templates and plugins but also by composing all the files that constitute the WordPress dashboard. This versatile scripting language provides us with extensive capabilities when it comes to building and managing websites. Here are some of the most common consequences of not keeping it updated:

  1. Security vulnerabilities: Outdated versions of PHP may have security vulnerabilities that hackers can exploit. Vulnerabilities can lead to data breaches and other security issues.
  1. Performance issues: Older versions of PHP may not be optimized for modern hardware and software, leading to slow performance and poor user experience.
  1. 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.
  1. 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.

Overall, keeping your PHP version updated is essential to ensure your website or application’s security, performance, and compatibility. When PHP becomes outdated, it can severely affect your website or application. When PHP becomes outdated, it can severely affect your website or application

Remember that running an outdated PHP version can impact your WordPress website’s security, performance, and functionality. It’s generally recommended to use a PHP version supported and actively maintained by WordPress and the hosting environment.

Addressing the Most Frequent Review Objections

Q: But I do have the most reviews overall! Why should I work to get 2 reviews a week when I have 300 more than my next closest competitor?

A: Because those 300 extra reviews likely happened over 5 years. Google doesn’t care. Google cares about which business is actively engaging now. Think of it this way: In a town with two bakeries, would you trust the one that was popular in 2018 or the one that has fresh 4.8-star reviews from yesterday?

Q: How can I automation reviews without looking “spammy” or robotic?

A: The key is timing and personalization. An email sent 4 days later is spam. An email triggered 24 hours later by their POS interaction, referencing their specific visit, and saying, “We love seeing you!” feels like a personalized follow-up. Keep your request language human and humble: “We’re a local business that thrives on honest feedback…” rather than “GIVE US 5 STARS!”

Q: Will getting a 4.1-star review on my 90-day rolling average hurt me more than helpful old 5-star reviews?

A: This is nuanced. A single, recent 4.1 review won’t “tank” you, as your overall (though less-weighted) average is still high. However, if your last 10 reviews in the 90-day window average to a 3.5, you will almost certainly drop in rankings, as Google sees you as a business that is currently underperforming, despite past success. This is why automation that triggers happy customers is critical.

Q: Is it true that Google filters “glowing” 5-star reviews as fake more than “authentic” average reviews?

A: No, that’s a myth. However, Google (and users) do look at patterns. Fifty identical, one-word “GREAT!” reviews left in two days will get flagged. A steady stream of slightly detailed (e.g., mentioning a specific employee or dish), varied (e.g., some detailed 4-star, some simple 5-star) reviews left consistently over weeks is the goal. Authenticity (a mix of opinions) does increase user trust, which improves conversion rate, but Google won’t penalize a legitimate string of recent 5-star acclaim.

Q: If the 90-day window is so critical, what happens if I go on vacation and get 0 reviews for two weeks?

A: This will absolutely create a “dip” in your ranking signals. While you won’t drop from #1 to #20 overnight, your competitors who continued to receive consistent feedback during those two weeks will gain algorithmic ground. This is the ultimate argument for automation. Your automation triggers reviews while you sleep, making your presence constant.

Q: My customers are mostly older/not tech-savvy. How can I possibly automate this or get them to leave a digital review?

A: This is a real challenge, but not insurmountable. Automation can adapt. Instead of automated SMS, use simplified technology: A physical table tablet at checkout that asks for email/phone, or a single-click “feedback” kiosk that opens a form (though this must be used carefully so it’s not a “captive review”). The most effective way is to pair automation (like the email) with a human script: Have staff hand them an appointment card with a QR code and say: “We love serving you! If you get an email from us tomorrow asking for feedback, we would truly value your perspective.”

Conclusion

The old playbook of gathering as many reviews as possible is dead. In 2026, dominance on Google Maps belongs to the businesses that have integrated review generation into their operational DNA.

Success in local SEO now requires prioritizing Review Velocity over total quantity. It demands recognizing the overwhelming influence of the current 90-Day Window. By naturally automating your review acquisition—from post-appointment emails to SMS triggers at point-of-sale—you are ensuring a sustainable, steady stream of feedback that proves to Google and customers alike that your business is vibrant, reliable, and relevant today.

Stop focusing on the count. Start focusing on the flow.
