Start Minecraft server with external PHP script?

I raise a server (A) and a server (B)

A web server with a web panel runs on server (A)

Minecraft Server is running on server (B)

I want to start the Minecraft server with the web panel on server (A). Is that possible?

If the server is down, nothing can arrive there

Yes, that is clear to me, but I just want the server "Minecraft ended" not to shut down but to end minecraft
