PHP Version in cPanel

For WordPress sites, we recommend PHP 8.1 or 8.2. These versions offer excellent performance, full compatibility with WordPress core and most plugins. PHP 8.2 brings up to 20% speed improvement over PHP 7.4. WordPress 6.x officially supports PHP 8.0-8.5, but PHP 8.1 and 8.2 have the best plugin and theme compatibility. Avoid PHP 7.4 which no longer receives security patches.

Yes, changing the PHP version can cause issues if your plugins, themes or custom code use deprecated PHP functions. That is why it is important to: take a full backup before changing, test on a staging environment if possible, check plugin compatibility, and have a rollback plan. On BeoHosting, you can easily roll back to the previous PHP version via cPanel if issues arise.

Several ways: in cPanel open MultiPHP Manager and you see the PHP version for each domain. In WordPress, go to Tools → Site Health → Info → Server where the PHP version is shown. You can also create a phpinfo.php file with and open it in the browser. Do not forget to delete phpinfo.php after the check — it reveals sensitive server info.

We recommend updating PHP every time a new stable version becomes available and your plugins confirm compatibility — typically 2-3 months after release. Each PHP version has active support for 2 years and security patches for one additional year. Follow the PHP lifecycle page for support deadlines. On BeoHosting, new PHP versions are available after the initial stabilization period.

OPcache is a PHP extension that caches compiled PHP code in memory, which dramatically speeds up script execution. On BeoHosting, OPcache is enabled by default and optimally configured. You can check status in phpinfo() or via cPanel. Key settings: opcache.memory_consumption=128, opcache.max_accelerated_files=10000, opcache.revalidate_freq=60. Do not disable OPcache except for debugging.
