What is PHP

PHP (Hypertext Preprocessor) is a server-side programming language for dynamic websites. Over 77% of server-side websites use PHP, including WordPress, Drupal, Joomla, Magento, Laravel, and many more.

PHP Version

PHP 8.2 or 8.3 is recommended for 2024-2025 — 3× faster than PHP 7.4 with many new features. PHP 7.4 is End of Life with no security updates, so upgrade. PHP 8.0/8.1 still receive security support, but 8.2/8.3 is best.

What is OPcache

OPcache caches compiled PHP bytecode in memory instead of parsing and compiling on every request — making PHP 3-5× faster. Good hosting enables OPcache automatically.

What is PHP-FPM

PHP-FPM (FastCGI Process Manager) is a better PHP execution method than Apache's mod_php. It runs as a separate process pool, not tied to the web server, handling more concurrent connections more efficiently. Nginx + PHP-FPM is the most popular combination.

PHP Memory Limit Timeout

Memory Limit controls how much RAM a PHP script can use. WordPress needs minimum 128MB; 256MB is recommended. WooCommerce or heavy plugins need 512MB+. Max Execution Time defines the script timeout — don't set it higher than necessary.

PHP Extension

Essential extensions: GD/Imagick (images), cURL (HTTP requests), MySQLi/PDO (database), mbstring (Unicode), openssl (SSL), zip (file compression), XML/SimpleXML (XML), intl (internationalization). WordPress requires almost all of these.

Error Reporting Production

On production servers, never display errors to users — they reveal paths, variables, and server information hackers can exploit. In php.ini: display_errors=Off, log_errors=On, error_log=/path/to/error.log.

Performance PHP Application

Key PHP performance factors: newer PHP version, OPcache, PHP-FPM, MySQL optimization (query cache, indexes), Redis Object Cache for WordPress, and CDN for static files.

PHP Version Hosting

Most hosting allows easy switching through cPanel or DirectAdmin → Software → PHP Version. Test on staging first. Verify all plugins/themes are compatible with the new PHP version before switching production.

Frequently Asked Questions (FAQ)

How is PHP 8.3 different from PHP 8.2?
PHP 8.3 is slightly faster and adds new features such as Typed Class Constants and a new Random Extension. It is mostly backward compatible with PHP 8.2. If your plugins/themes support PHP 8.3, upgrading is recommended. Security support for PHP 8.2 runs until 2026.
How much PHP RAM does WordPress need?
WordPress needs 64MB at a basic level, but typical plugins require 128-256MB. WooCommerce plus many plugins needs 256-512MB. If your site is slow or you see the error "Fatal error: Allowed memory size", increase memory_limit in php.ini or wp-config.php.
How do I check which PHP extensions are available?
Create a phpinfo.php file containing only phpinfo(), upload it to your hosting, and open it in a browser to see all enabled extensions. Delete the file after checking for security reasons. Don't leave it on production.
Can OPcache prevent edited code from updating immediately?
Yes. If opcache.validate_timestamps=0 (production optimized), OPcache won't check whether files have changed, so you must flush OPcache after editing code. The fix: set opcache.revalidate_freq=0 or clear the cache after deploy.
