Description

To try resolve problem https://github.com/swagger-api/swagger-codegen/issues/10896 in yaml try to use allOf; Codegen creates duplications methods.

....
'is_catchall' => 'getIsCatchall',
....
'is_catch_all' => 'getIsCatchAll',
....  ];

Swagger declaration file content or url

<https://github.com/go-email-validator/email-validator-sdk/blob/e99fe82d3c9d6d520687cf499688112e86acfe03/ev.openapiv3.yaml#L227

Command line used for generation

  docker run --rm -v ${PWD}/php:/local/out -v $(OPENAPI_PATH):/local/openapi.yaml swaggerapi/swagger-codegen-cli-v3:latest generate \
    -i /local/openapi.yaml \
    -l php \
    -o /local/out/

Start with the OpenAPI declaration at the linked ev.openapiv3.yaml location and reproduce generation with the documented Docker command using swagger-codegen-cli-v3:latest. Inspect the generated PHP getters and static getter map; done means an allOf case with the two field names does not create duplicate methods or mappings.
