PHP versions are critical for WordPress hosting, impacting both performance and security. However, like checking smoke detectors, many site operators neglect PHP updates until problems arise. With PHP 7.4 reaching its security support end on November 28, 2022, the urgency to upgrade becomes paramount.
PHP is a scripting language that powers over three-fourths of all websites, including WordPress. It processes the code that renders your WordPress pages, affecting core files, themes, and plugins. The version your server runs can significantly influence your site’s speed and security.
WordPress 6.0, released in May 2022, requires PHP version 7.4 or greater. While older versions may technically work, they pose security risks. PHP versions receive full support for two years, followed by a year of security updates. After this period, they reach end-of-life, leaving sites vulnerable to unpatched vulnerabilities.
Why Upgrade Your PHP Version
Upgrading PHP is essential for multiple reasons. Outdated versions slow down your site, whereas newer versions enhance speed. Security optimization is critical; using unsupported PHP versions is akin to leaving your front door open on vacation—an invitation for trouble. New PHP releases also bring features that theme and plugin developers leverage, such as those in PHP 8.0. Moreover, some hosts require updated PHP versions to offer their own support services.
How to Upgrade PHP Versions Safely
Checking your current PHP version is straightforward. Pressable and other hosts offer tools within their control panels. Alternatively, WordPress admin users can navigate to “Tools” and “Site Health” to find this information. Ensuring your hosting provider supports newer PHP versions is crucial; Pressable guarantees compatibility with the latest versions.
Before switching PHP versions, create a site backup. This precaution protects against potential issues from updates to plugins and themes. It’s advisable to update your WordPress installation to the latest version before changing PHP versions. Managed hosting plans typically handle this automatically.
To switch PHP versions, log into your hosting account and follow the provider’s instructions. Pressable users receive specific guidance for this process. Ideally, perform the upgrade on a staging site first to verify compatibility before applying changes to the live site.
Resolving Potential Post-Upgrade Issues
After upgrading PHP, check for errors by reviewing PHP error logs. Problems often stem from themes or plugins. Troubleshoot by switching to a default theme and deactivating plugins, reactivating them one by one to identify the source of any issues. Custom code may also require adjustments.
