What is PHP?

PHP (Hypertext Preprocessor) is an open-source, general-purpose server-side scripting language created by Rasmus Lerdorf in 1994. Powering over 75% of websites with known server-side languages—including WordPress, Wikipedia, and Laravel—modern PHP 8 is fast, strongly typed, and feature-complete. It features Just-In-Time (JIT) compilation, union types, attributes, fibers, and rich database drivers.

PHP Code Examples & Syntax Cheat Sheet

Explore modern PHP 8 patterns below. Click "Try Now" on any example to instantly execute it in the online editor:

1. Hello World with Modern PHP 8 Features

Clean PHP script demonstrating string interpolation and version information.

<?php
$platform = "ToolPix";
$version = PHP_VERSION;

echo "Welcome to {$platform} Online PHP Compiler!\n";
echo "Running on PHP Version: {$version}\n";
?>

2. PHP 8 Match Expressions & Named Arguments

Replacing traditional verbose switch statements with modern match expressions.

<?php
function getStatusCodeMessage(int $status): string {
    return match ($status) {
        200, 201 => "Success: Request completed",
        400 => "Client Error: Bad Request",
        401, 403 => "Auth Error: Unauthorized",
        404 => "Not Found: Resource does not exist",
        500 => "Server Error: Internal server issue",
        default => "Unknown Status Code",
    };
}

echo getStatusCodeMessage(200) . "\n";
echo getStatusCodeMessage(404) . "\n";
?>

3. Associative Arrays & JSON APIs

Handling dictionaries, associative arrays, and JSON serialization with json_encode.

<?php
$apiResponse = [
    "status"  => "success",
    "service" => "toolpix-compiler",
    "data"    => [
        ["id" => 1, "tool" => "PHP Compiler", "active" => true],
        ["id" => 2, "tool" => "Python Compiler", "active" => true],
        ["id" => 3, "tool" => "Rust Compiler", "active" => true],
    ],
    "timestamp" => time(),
];

echo json_encode($apiResponse, JSON_PRETTY_PRINT) . "\n";
?>

4. Object-Oriented PHP: Constructor Promotion

Clean class definitions in PHP 8 without boilerplate property declarations.

<?php
class ServerNode {
    public function __construct(
        public readonly string $hostname,
        public readonly string $ip,
        public int $load = 0
    ) {}

    public function getStatus(): string {
        return "Node: {$this->hostname} ({$this->ip}) - Load: {$this->load}%";
    }
}

$server = new ServerNode(hostname: "web-01.toolpix.dev", ip: "10.0.0.1", load: 35);
echo $server->getStatus() . "\n";
?>

5. Regular Expressions & String Parsing

Validating email formats and extracting data with preg_match.

<?php
$email = "developer@toolpix.dev";
$pattern = '/^([a-z0-9_\.-]+)@([\da-z\.-]+)\.([a-z\.]{2,6})$/';

if (preg_match($pattern, $email, $matches)) {
    echo "Valid email address: {$email}\n";
    echo "Username: {$matches[1]}\n";
    echo "Domain: {$matches[2]}.{$matches[3]}\n";
} else {
    echo "Invalid email format.\n";
}
?>
