Adding MSSQL Extension for PHP to My Webapp

What type of hardware are you using: Virtual machine
What YunoHost version are you running: 12.0.17 (stable)
What app is this about: My Webapp

Describe your issue

I need to add and enable MSSQL extension for PHP.
I have datas that needs to be parsed from MSSQL but Yunohost does not have drivers installed.
I have checked PHP directory to see MSSQL extension/driver but could not find.
Before trying anything, I wanted to ask to community.

Share relevant logs or error messages

I have checked if driver or php extension was installed, but could not find it. I assume it is not installed.

I have found below article to add MSSQL support to Debian but I believe every Apache and PHP update could break it. Is that so?
