JSON to PHP Converter

PHP applications process JSON extensively through json_decode() and json_encode() functions, but modern PHP development increasingly uses typed class models rather than raw arrays for better IDE support and code reliability. The AllTools JSON to PHP converter generates PHP 8+ class definitions with typed properties, constructor promotion, and proper type mappings: JSON strings become string, numbers become int or float, booleans become bool, nullable values become nullable types (?string), nested objects become separate classes, and arrays become typed arrays (array with PHPDoc @var annotations for element types). Constructor promotion (public function __construct(private string $name)) reduces boilerplate dramatically compared to separate property declarations and constructor assignments. The converter produces code compatible with PHP 8.0+ features including named arguments, union types (string|int), and readonly properties. For Laravel applications, the output can serve as the basis for Data Transfer Objects (DTOs), API Resources, or Form Request validation rules. All generation happens in the browser — your API data stays on your device.

Modern PHP frameworks have sophisticated JSON handling that builds on the basic json_decode()/json_encode() functions. Laravel's API Resources transform Eloquent models into JSON responses with precise control over included fields, relationships, and conditional attributes. Laravel Data by Spatie provides TypeScript-style data objects with validation, transformation, and serialization built in. Symfony's Serializer component handles complex object-to-JSON mapping with normalizers and encoders. PHP 8.1's enum types map cleanly to JSON string values for status fields and categorical data. PHP 8.2's readonly classes create immutable value objects ideal for API response models. For REST API consumption, Guzzle HTTP client combined with typed DTOs provides type-safe API integration. The json_decode() function returns stdClass objects by default — passing true as the second argument returns associative arrays instead. For production applications, implementing JsonSerializable interface gives classes complete control over their JSON representation. The AllTools converter generates modern PHP classes that developers customize with Laravel attributes, Symfony annotations, or custom serialization logic.
