How to deploy PHP and React on vercel [closed]

I got error on vercel after deploy

Here is project directory and file structure

and my vercel.json file is

    {
    "functions": {
      "server/controller/*.php": {
        "runtime": "[email protected]"
      },
  
  
      "server/controller/authController.php": {
        "runtime": "[email protected]"
      },
      "server/controller/employeeController.php": {
        "runtime": "[email protected]"
      }
    }
  }

Let me know how to resolve it and correct way to deploy on Vercel.
