PHP structures from JSON samples

PHP apps often start with associative arrays until types help. CalcForge converts JSON examples into class definitions or documented shapes you can use in Laravel resources, Symfony serializers, or static analysis with PHPStan.

Good fits

  • Modeling payment gateway callbacks in Laravel
  • Creating DTO classes for Symfony API Platform
  • Documenting expected webhook keys for junior developers
  • Jump-starting typed properties in PHP 8+ codebases
JSON:
{"invoiceId":"INV-9","amount":120.5}

PHP:
class Root {
    public string $invoiceId;
    public float $amount;
}

Practical notes

  • Promote properties to constructor promotion or readonly as your style guide prefers.
  • Add `@var` array shape docblocks when staying array-first instead of classes.
  • Validate with `json_decode` plus manual asserts before trusting generated types.

Frequently asked questions

Does it generate Laravel Eloquent models?

Output is plain PHP classes—adapt to Eloquent models with `$fillable` and relationships yourself.

Are typed properties PHP 8+ compatible?

Yes. Scalar and class property types follow JSON value shapes in modern syntax.

How are nested objects represented?

Nested JSON objects become separate class definitions referenced by property type hints.
