Open PHP Page and Get Error

[MarkSky]

I use this extension to open a php web.
my setting is:

"liveServer.settings.CustomBrowser": "chrome",
"liveServer.settings.port": 8800,
"liveServer.settings.proxy": {
    "enable": true,
    "baseUri": "/",
    "proxyUri": "http://127.0.0.1:8800"
},

and after starting, the browser display:

Error: socket hang up
at createHangUpError (_http_client.js:302:15)
at Socket.socketOnEnd (_http_client.js:394:23)
at emitNone (events.js:91:20)
at Socket.emit (events.js:188:7)
at endReadableNT (_stream_readable.js:975:12)
at _combinedTickCallback (internal/process/next_tick.js:80:11)
at process._tickCallback (internal/process/next_tick.js:104:9)

If I setting it wrong?

The error is Error: socket hang up. I'm not quite sure why it is for! I need few info..!

Where your PHP code is running (I mean, at which port) ?

[MarkSky]

Do you mean the liveServer setting in my VSCode?
I use '8800'.

[ritwickdey]

No! No! Not Live Server, forget about Live Server. If you don't have live server, what you'll do to test the PHP code ? (May be you'll start XAMPP or IIS or through CLI).

[MarkSky]

Oh! I know what you mean. I don't use other sever. I thought Live Server could replace IIS Express. So I didn't run any server.

[ritwickdey]

Sorry! "Live Server Web Extension" for live reload, not serving the page. I know the documentation is not clear - I apologized for it.

You need 2 server, one that will server your page. Another for live reload

[MarkSky]

Ok, thank you for your reply.

[ritwickdey]

Run the php code through IIS Express or something like that. (Assuming the port in 3000)

live server config:

"liveServer.settings.CustomBrowser": "chrome",
"liveServer.settings.port": 8800,
"liveServer.settings.proxy": {
    "enable": true,
    "baseUri": "/",
    "proxyUri": "http://127.0.0.1:3000"
},

Now use the 127.0.0.1:8800 for live reload.
