Your First Script

Running a script

Create a file called app.php:

<?php

$name = "world";
echo "Hello, $name!\n";

$numbers = [1, 2, 3, 4, 5];
$doubled = [];
foreach ($numbers as $n) {
    $doubled[] = $n * 2;
}
echo implode(", ", $doubled) . "\n";

Run it:

$ zphp run app.php
Hello, world!
2, 4, 6, 8, 10

Serving an application

Create a file called server.php:

<?php

$method = $_SERVER['REQUEST_METHOD'];
$path = $_SERVER['REQUEST_URI'];

echo json_encode([
    'method' => $method,
    'path' => $path,
    'message' => 'Hello from zphp',
]);

Serve it:

$ zphp serve server.php --port 3000
listening on http://0.0.0.0:3000 (14 workers)

$ curl http://localhost:3000/api/hello
{"method":"GET","path":"\/api\/hello","message":"Hello from zphp"}

That's a production HTTP server running from a single command. See Serving an Application for the full details.
