🔄 JSON to PHP Class

What is JSON to PHP Class Converter?

The JSON to PHP Class Converter is a free online developer tool that instantly converts JSON data into PHP class definitions. It automatically identifies JSON field types and maps them to PHP types, supporting nested object class generation, PHP 8 named argument constructors, typed property declarations, and getter/setter method generation. Perfect for Laravel/Symfony developers who need to quickly generate model classes from API responses, dramatically reducing manual PHP class writing. All conversion happens locally in your browser — no data is ever uploaded to a server.

Core Features

• Smart Type Mapping: Auto-detects string→string, number→int/float, boolean→bool, array→array, null→nullable types
• Nested Classes: Nested JSON objects are automatically generated as separate PHP class definitions
• Constructors: Supports PHP 8 named argument constructors or PHP 7 traditional constructors
• Getter/Setter: Optionally generate getter and setter methods for business logic extension
• Multi-Version: Supports PHP 8.x, 7.4+, and 7.x syntax variants

How to Use

1. Paste your JSON data into the input area, or click "Load Example" to try it quickly.

2. Set the class name and conversion options: PHP version, constructor, getter/setter, etc.

3. Click "Convert" or use Ctrl+Enter to execute.

4. View the generated PHP class code in the result area below.

5. Click "Copy Code" to copy to clipboard, or download as a .php file.

Use Cases

Laravel Models

When integrating APIs, paste JSON responses to instantly generate Eloquent model or DTO classes for Laravel projects.

Symfony Entities

Quickly generate entity classes from JSON Schema with Symfony, combined with ORM annotations for faster development.

API Clients

PHP backend developers calling third-party APIs can generate type-safe response classes from JSON responses.

Config Mapping

Map JSON configuration files to PHP classes for type-safe configuration access.

Technical Background

PHP 7.4 introduced typed properties, allowing type specification in property declarations. PHP 8.0 enhanced the type system with union types (e.g., int|string) and named arguments for clearer constructor calls. PHP 8.1 added enums, and PHP 8.2 supports readonly classes. In Laravel, Eloquent models typically use the $casts property for JSON field type conversion. The DTO (Data Transfer Object) pattern is increasingly popular in PHP for passing type-safe data between layers.
