PHP Editor

iwantcoding.com ships an in-browser PHP editor that runs real PHP via php-wasm — PHP compiled to WebAssembly. Type code on the left, press Run », see output on the right.

What you can do

• Run any PHP you write — echo, print_r, var_dump all stream into the output pane.
• Use the standard library — json, preg_*, str_*, array_*, DateTime, SPL, and more.
• Define classes, interfaces, traits, enums. Modern PHP 8.x syntax is fully supported.
• Pick from ready-made sample programs in the toolbar dropdown.

Things to know

• The script runs as a one-shot CLI — no Apache, no $_GET / $_POST / $_SESSION. For form examples, simulate the data: $_POST['name'] = 'Ada';.
• File I/O writes to an in-browser virtual filesystem.
• No network — file_get_contents('https://…') can't reach the internet. Use the simulated examples instead.
• Heavy extensions (PDO drivers, gd, imagemagick) aren't included.

Sample to try

<?php
$status = 'paid';
echo match ($status) {
    'paid'      => 'OK',
    'pending'   => 'Awaiting',
    'refunded'  => 'Refund issued',
    default     => 'Unknown',
};

Example
