What Is PHP and Where Is It Used?

PHP is the scripting language that powers many popular content management systems, including WordPress, Joomla and Drupal. Your hosting server uses PHP to generate dynamic pages every time a visitor loads your site.

Benefits of Updating PHP

• Performance improvements from newer engines.
• Security patches that protect against known vulnerabilities.
• Access to modern language features for developers.

How to Upgrade PHP Safely

Before changing your PHP version, create a full backup and test compatibility on a staging site. Many hosting control panels let you switch PHP versions with a few clicks.

Practical Recommendation

Use a currently supported PHP branch recommended by your CMS. Avoid outdated versions that have reached end of life and no longer receive security updates.
