How to add YAML module to OpenServer5.3?

Question

DLL

You need to install the yaml module in OpenServer to display the site correctly.
I downloaded the yaml.dll file from the link: https://windows.php.net/downloads/pecl/releases/ya...
threw it along the path: D:\open_server_5_3_0_basic\OSPanel\modules\php\PHP_7.0-x64 ,
in php.ini added two files because I don’t know which one to add (I added it separately, it doesn’t work either) extension=php_yaml.dll and extension=yaml.dll.
Maybe someone faced the same problem and can help to solve.
Thanks :)
Site display error:
Fatal error: Uncaught Error: Call to undefined function yaml_parse_file()
