hi friends,I saw you contribute code to php-src project.
for example the file of php-src/ext/json/json.stub.php
I am also a php programer. I am from China.
I want to know how to generate the stub file as json.stub.php for the php extension.
I saw the stub.php file in every extension.
I think it should not maintence by manual. I should generate by command .
Do you know the generate method?
Thanks

@fanqingxuan, actually, the foo_arginfo.h files are generated from foo.stub.php by doing php scripts/dev/gen_stub.php foo.stub.php. Usually, this happens automatically.
