Problem to generate helper class for PHP with protoc and sparkplug_b.proto

[marcoratto]

Hi,
Im'm trying to generate the helper class for PHP but I have the errors with different version of the tool protoc.

protoc --version
libprotoc 32.0

protoc --php_out=src sparkplug_b.proto
--php_out: Can't generate PHP code for closed enum org.eclipse.tahu.protobuf.DataType. Please use either proto3 or editions without enum_type = CLOSED.
protoc --version
libprotoc 3.21.12
protoc --php_out=src sparkplug_b.proto
sparkplug_b.proto:91:41: Extension ranges are not allowed in proto3.

protoc --php_out=src sparkplug_b.proto
--php_out: Can only generate PHP code for proto3 .proto files.
Please add 'syntax = "proto3";' to the top of your .proto file.

How can I solve it ?
