PHP and WordPress

WordPress is built with PHP, which runs on your server to generate the HTML pages visitors see in their browsers. Understanding PHP basics helps Toronto business owners make informed decisions about their website. WordPress currently requires PHP 8.0 or higher, with PHP 8.2 recommended for optimal performance and security.

PHP Version and Performance

PHP 8.2 delivers significant performance improvements over older versions — up to 2-3x faster than PHP 7.4. SiteGround offers easy PHP version switching from their control panel. Always use the latest stable PHP version supported by your WordPress themes and plugins. Outdated PHP versions are both slower and less secure, creating unnecessary performance and security risks for your Toronto business website.

When You Need Custom PHP

Most Toronto businesses never need to write PHP code — WordPress plugins handle common functionality. Custom PHP becomes necessary when you need features that no plugin provides, want to integrate with third-party APIs, need to modify WordPress default behaviour, or require custom shortcodes or widgets. When custom PHP is needed, use WPCode plugin for snippet management rather than editing theme files directly, ensuring updates don’t overwrite your customizations.
