How It Works
- 1
Paste JavaScript or Node.js Code
Input your JavaScript functions, ES6 classes, Express routes, or async/await patterns. The converter handles both frontend JavaScript and Node.js backend code.
- 2
AI Analyzes Async Patterns and Class Structures
The AI identifies Promise chains, async/await blocks, arrow functions, template literals, and destructuring. It maps JavaScript array methods to PHP equivalents and converts ES6 class syntax to PHP class definitions.

Review PSR-Compliant PHP Output
Receive PHP code with proper type hints (PHP 7.4+), PSR-2 formatting, namespace declarations, and synchronous execution patterns. Express routes convert to framework-agnostic routing logic compatible with Laravel or Symfony.
JavaScript vs PHP: Language Comparison
| Feature | JavaScript | PHP |
|---|---|---|
| Execution Model | Event-driven, non-blocking | Request-response, blocking |
| Type System | Dynamic, optional TypeScript | Dynamic with type hints (PHP 7+) |
| Async Handling | async/await, Promises | Synchronous or ReactPHP/Amp |
| Package Manager | npm, yarn | Composer |
| Server Framework | Express, Koa, Fastify | Laravel, Symfony, Slim |
| Array Methods | map, filter, reduce | array_map, array_filter, array_reduce |
Code Examples
Example 1: Async Function to Synchronous PHP
// JavaScript with async/await
async function fetchUserData(userId) {
const response = await fetch(`/api/users/${userId}`);
const data = await response.json();
return data.name;
}
const users = [1, 2, 3].map(id => fetchUserData(id));<?php
// PHP synchronous equivalent
function fetchUserData(int $userId): string {
$response = file_get_contents("/api/users/{$userId}");
$data = json_decode($response, true);
return $data['name'];
}
$users = array_map('fetchUserData', [1, 2, 3]);Key Changes:
Note how JavaScript's async/await pattern converts to synchronous PHP function calls. The fetch API becomes file_get_contents or cURL. Template literals convert to PHP string interpolation. Arrow functions and array methods (map) translate to array_map with callback functions. Type hints are added for PHP 7.4+ compatibility.
Example 2: ES6 Class to PHP Class
// JavaScript ES6 class
class UserRepository {
constructor(database) {
this.db = database;
}
async findById(id) {
const user = await this.db.query('SELECT * FROM users WHERE id = ?', [id]);
return user[0];
}
static create(config) {
return new UserRepository(config.database);
}
}<?php
// PHP class with type hints
class UserRepository {
private $db;
public function __construct($database) {
$this->db = $database;
}
public function findById(int $id): ?array {
$stmt = $this->db->prepare('SELECT * FROM users WHERE id = ?');
$stmt->execute([$id]);
$user = $stmt->fetch(PDO::FETCH_ASSOC);
return $user ?: null;
}
public static function create(array $config): self {
return new self($config['database']);
}
}Key Changes:
JavaScript ES6 class syntax maps directly to PHP classes with similar structure. The constructor method converts to __construct with property initialization. Async methods become synchronous with PDO prepared statements replacing promise-based database queries. Static methods retain the static keyword. PHP requires explicit visibility modifiers (private, public) and supports return type hints (?array for nullable).
Frequently Asked Questions
JavaScript's async/await converts to synchronous PHP code by default. Non-blocking I/O patterns become blocking calls. True asynchronous execution requires PHP extensions like ReactPHP or Amp. Promise chains convert to sequential function calls. Event loop patterns need significant restructuring for PHP's request-response model.
No. All JavaScript to PHP conversion happens entirely in your browser using client-side AI models. Your code never leaves your machine, is not logged, and is not transmitted to any external servers. The tool works offline once loaded.
The converter handles core language syntax with 95%+ accuracy. Express routes convert to PHP routing patterns compatible with Laravel/Symfony. However, npm packages require manual mapping to Composer equivalents. Database ORM calls (Sequelize to Eloquent) need review. Complex middleware patterns may require adjustments for PHP's execution model.
