PHP

PHP (Hypertext Preprocessor) is a server-side scripting language designed primarily for web development. Created by Rasmus Lerdorf in 1994, PHP has grown into one of the most widely deployed web languages, powering approximately 77% of all websites with a known server-side language, including platforms like WordPress, Drupal, and Magento. PHP code executes on the server and generates HTML that is sent to the client’s browser.

How PHP Works

PHP is an interpreted language, meaning code is executed line by line at runtime rather than being compiled beforehand. When a user requests a PHP page, the web server passes the file to the PHP interpreter, which processes the code, interacts with databases or other services as needed, and returns the output (typically HTML) to the server for delivery to the browser.

PHP integrates seamlessly with databases like MySQL, PostgreSQL, and SQLite, making it a natural fit for data-driven web applications. It supports all major web servers including Apache, Nginx, and LiteSpeed, and runs on Linux, macOS, and Windows. Most shared hosting plans include PHP by default.

Modern PHP

PHP has undergone substantial modernization since the release of PHP 7 in 2015 and PHP 8 in 2020. These versions introduced significant performance improvements (PHP 7 was twice as fast as PHP 5.6), strict typing, named arguments, attributes, enums, fibers for concurrency, and a just-in-time (JIT) compiler. Modern PHP bears little resemblance to the language that earned criticism in its earlier years.

The PHP ecosystem includes Composer for dependency management, robust frameworks like Laravel and Symfony, and comprehensive testing tools like PHPUnit. Laravel in particular has driven renewed interest in PHP by offering an expressive, developer-friendly experience for building web applications and APIs.

When to Choose PHP

PHP remains an excellent choice for web applications, content management systems, ecommerce platforms, and APIs. Its gentle learning curve, massive community, abundant hosting availability, and extensive documentation make it accessible to developers at all levels.

For businesses evaluating web technologies, the decision often comes down to existing infrastructure and team expertise. Explore PHP web frameworks to find the right framework for your next project.
