Many web hosts only update PHP when it becomes absolutely necessary, further complicating version management.

The panel not only provides information on your PHP version but also enables you to make version changes and manage modules. Utilizing cPanel remains the recommended approach for checking your PHP version, especially for its security and simplicity.

After obtaining the necessary PHP version information, it is essential to prioritize website security. Delete the “phpversion.php” file you created to prevent unauthorized access. Leaving such files accessible could expose your website to potential security threats, as hackers may exploit information about your PHP version to identify vulnerabilities.

Conclusion:

Understanding and managing the PHP version of your WordPress site is vital for ensuring optimal performance, security, and compatibility with plugins and themes. The dynamic relationship between PHP and WordPress underscores the importance of staying current with PHP versions.
