About PHP

PHP is a server-side scripting language designed for web development. It powers more than 75% of all websites with a known backend technology — WordPress, Wikipedia, Slack, Mailchimp, Etsy, and Shopify all run substantial PHP. Created by Rasmus Lerdorf in 1994 and now maintained by The PHP Group, modern PHP 8.x is a fast, JIT-compiled language with optional strict typing, readonly properties, enums, named arguments, first-class callable syntax, and mature frameworks like Laravel, Symfony, Yii and CodeIgniter. Run any PHP 8 script in this browser-based compiler — no XAMPP, MAMP, or Docker required.

Hello World in PHP

<?php
// Hello World in PHP
$languages = ['Python', 'Rust', 'Go', 'PHP'];
foreach ($languages as $lang) {
    echo "Hello from $lang!\n";
}

// Bonus: PHP 8 match expression
$year = 2026;
$era = match(true) {
    $year >= 2020 => 'modern PHP',
    $year >= 2010 => 'PHP 5 era',
    default       => 'classic PHP',
};
echo "We live in the $era.\n";

When to use PHP

Use PHP for server-side web development: REST APIs, WordPress themes and plugins, Laravel and Symfony applications, e-commerce back-ends, content management systems, and database-driven dynamic websites. PHP shines for rapid prototyping of CRUD apps thanks to its 'embed inside HTML' design and massive ecosystem. Pair it with MySQL or MariaDB for the classic LAMP stack, or PostgreSQL for modern Eloquent ORM workflows. It's also the standard scripting language for sysadmin tasks on most shared hosting providers.

Common questions

Which PHP version does this online compiler run?

PHP 8.x — the latest stable line. It supports JIT compilation, readonly properties, enums, first-class callable syntax, named arguments, and the full modern type system. Older PHP 7.x and 5.x scripts also run since 8.x is largely backward-compatible for typical use.

Can I use Composer packages in this online PHP compiler?

Standalone single-file scripts run without Composer setup. For framework-style code (Laravel, Symfony, Slim) you need a full project structure that this single-file compiler isn't designed for — use a local dev environment or a hosted sandbox like 3v4l.org for that. Built-in PHP extensions (PDO, JSON, mbstring, OpenSSL, GD, cURL) are all available.

Why is PHP still relevant in 2026?

Ecosystem mass. WordPress alone runs about 43% of the web, Laravel is the most-loved PHP framework on the Stack Overflow developer survey, and Shopify, Wikipedia, Slack, Etsy, Mailchimp, and Tumblr all run substantial PHP in production. The language itself has modernised aggressively: PHP 8.4 brought property hooks and asymmetric visibility, closing the gap with C# and Kotlin on language ergonomics.
