How to take input in PHP online

myCompiler supports standard input (stdin) for PHP programs. Use PHP's standard input functions to read user input. Enter your input data in the stdin panel before running your program.

This works for both single-line and multi-line input. You can read strings and convert to numbers using the language's built-in I/O functions.

Try it yourself

main.php stdin supported

<?php
$name = trim(fgets(STDIN));
$age = intval(trim(fgets(STDIN)));

echo "Hello $name!\n";
echo "You'll be " . ($age + 1) . " next year.\n";

stdin

Alice
25

Output

Hello Alice!
You'll be 26 next year.

What is PHP?

PHP is a widely-used, open-source server-side scripting language originally created by Rasmus Lerdorf in 1994. PHP was purpose-built for web development, it is embedded directly in HTML, runs on the server, and generates dynamic web pages. Today, PHP powers over 75% of all websites with a known server-side language, including WordPress, Facebook (which started on PHP), and Wikipedia.

Modern PHP (PHP 8.0+) is a mature, type-safe language with features like named arguments, match expressions, union types, enums, fibers, and readonly properties. PHP 8 with the JIT compiler significantly improved performance. The Laravel and Symfony frameworks have elevated PHP's reputation as a platform for building sophisticated, well-architected applications.

What is PHP used for?

PHP is used for web application development with frameworks like Laravel and Symfony, content management systems (WordPress powers 43% of all websites, Drupal and Joomla also run on PHP), e-commerce platforms (Magento, WooCommerce), REST API backends, and server-side templating. Laravel in particular has a comprehensive ecosystem with authentication, queues, WebSockets, and ORM.

PHP for beginners

PHP is one of the most accessible languages for learning web development. A PHP script runs immediately on any shared hosting server, making deployment trivially easy. The language's permissive syntax and immediate visual feedback (output appears in the browser) make it approachable for beginners. Use myCompiler's online PHP compiler to learn PHP fundamentals, arrays, functions, classes, and string manipulation, without setting up a LAMP stack locally.

PHP vs other languages

Compared to Python/Django or Ruby/Rails, PHP is more tightly integrated with web servers and has lower hosting costs due to widespread shared hosting support. Compared to Node.js, PHP has a more traditional synchronous execution model but Laravel's ecosystem rivals Express/Fastify for building APIs. Modern PHP 8 has addressed many historical criticisms about the language's design.

Why use an online PHP compiler?

An online PHP compiler, also called a PHP sandbox or PHP fiddle, lets you run PHP code directly in your browser without installing PHP or a web server. This is useful for testing PHP functions, practicing object-oriented PHP, experimenting with string and array manipulation, and quickly validating PHP logic without a local development environment.

myCompiler's online PHP IDE runs modern PHP with support for classes, interfaces, traits, named arguments, match expressions, and the PHP standard library. Write multi-file PHP programs, provide stdin input, and save and share your programs via URL, completely free.

Why is PHP so popular?

PHP's dominance of the web is largely attributable to WordPress, which alone runs on 43% of the world's websites. Despite competition from Python, Node.js, and Ruby, PHP remains entrenched in web infrastructure that powers millions of businesses. The Laravel framework has revitalized PHP's reputation among developers, offering an elegant, expressive syntax and a full ecosystem for building modern web applications. PHP's near-zero cost of hosting on shared servers keeps it the pragmatic choice for web developers worldwide.

PHP career opportunities

PHP skills lead to web developer, WordPress developer, Laravel developer, backend PHP engineer, and full-stack developer roles. The enormous volume of PHP-powered websites creates consistent demand for PHP developers. Laravel expertise is particularly valued, as it has become the benchmark for modern PHP development.
