JSON → PHP classes

Client

Paste JSON to emit typed properties and list<T> phpdoc for arrays—add hydration with your framework or json_decode as needed.

Learn more: JSON and PHP

Generate PHP 8+ classes with typed properties and `list<…>` phpdoc for arrays—add hydration with your framework or json_decode/json_encode.

Scope

This is structural scaffolding; wire DTOs into your ORM or API client as your project requires. Mixed/null primitives use `mixed` as a placeholder.

JSON → PHP

?

Parses JSON in your browser and emits classes inferred from the sample shape. Nested objects become nested types; arrays use the first element only to guess item shape. Nothing is uploaded.

Typed properties target PHP 8+; add json_decode/json_encodeor your framework's hydrators as needed.

Common use cases

  • Outline typed classes for Laravel or Symfony HTTP clients from a JSON sample.
  • Document webhook payloads before writing validation rules.
  • Compare inferred array shapes with phpdoc list<> templates.

Common mistakes to avoid

  • Trusting strict_types without validating input

    Generated properties are hints; still validate and sanitize at the HTTP boundary.

  • Mixing associative arrays and objects inconsistently

    json_decode depth and object vs array flags change behavior—align with your framework’s conventions.

FAQ

Is PHP generation local?

Yes. Code is produced entirely in your browser.

Does this emit Symfony or Laravel attributes?

It outputs structural classes. Add framework annotations and serializers for your stack.
