Convert PHP classes and DTOs into JSON Schema, then open the Mock Generator to produce matching sample JSON.
Select which PHP class should be treated as the root when generating the schema.
Parsing runs entirely in your browser. Your source never leaves the page.
Paste your PHP classes to produce a JSON Schema instantly.
Supports typed properties, DocBlock annotations, nullable/union types, arrays, and associative maps.
This online PHP class to JSON Schema converter helps you generate JSON Schema from real models (DTOs, structs, and classes) so you can validate payloads, share contracts, and generate mock JSON.
Step 1 – Paste your PHP source
Step 2 – Select the Root class (if needed)
Step 3 – Review the JSON Schema output
definitions and $ref when your models reference other models.Step 4 – Validate or generate mock JSON
anyOf/oneOf/allOf), verify the result with a full validator like Ajv.Schema keyword support note
Generated schemas can include $ref and may be edited to include anyOf, oneOf, or allOf. For complex schemas, use a full JSON Schema validator and dereference before mock generation if needed.
Use these tools to validate schemas, generate mock payloads, format JSON examples, and keep code and contracts in sync.
Generate example JSON from your schema for testing, fixtures, and documentation.
Validate JSON against common schema keywords and find mismatches quickly.
Generate PHP types and models from JSON samples.
Build schema from representative JSON samples to complement model-first schemas.
Explore schema examples and patterns for objects, arrays, enums, and constraints.
Clean up JSON examples before validating against schema or sharing docs.
The converter reads class definitions with typed properties or DocBlock @var annotations, recognizing visibility modifiers, nullable types, arrays, and DateTime/UUID hints. Properties tagged as json-ignore or JsonIgnore are skipped automatically.
string, int, float, bool, array, and custom classes map to their JSON Schema counterparts. Nullable and union types mark fields optional, arrays become schema arrays, and array<string, T> patterns are treated as maps. Unknown classes fall back to string unless another PHP class with that name is defined.
Yes. You can paste DTOs, form requests, or entity classes with typed properties or DocBlock hints. The tool runs entirely in your browser, so your code never leaves your machine.
After generating the schema, click "Generate Mock Data" to open the Mock Generator with the schema preloaded. Configure locales and options to create sample payloads for docs or tests.
