I’ve started with Blank Workspace template for play with PHP on platform.  
So my question about configuration of dev.nix file  
I have index.php in root folder and I start Build-in PHP server with `onStart =` directive for workspace… But I don’t understans what i suppose to write for `previews = { enable = true; };` to see web preview for started server? Can you show me example?

Now IDX support PHP Template on Backend category.

Or try this config on your `dev.nix` file base on IDX PHP template.

```auto
    previews = {
      enable = true;
      previews = {
        web = {
          # Example: run "npm run dev" with PORT set to IDX's defined port for previews,
          # and show it in IDX's web preview panel
          command = ["php" "-S" "localhost:$PORT"];
          manager = "web";
          # env = {
          # # Environment variables to set for your server
          # PORT = "$PORT";
          # };
        };
      };
    };

```
