### Start
|
|
|
|
|
|
|
|
|
|
Create as many servers as wanted by providing different `type`, `host`, `port` and other arguments!
|
|
|
|
|
|
|
|
|
|
* for security reasons, `next` server prevents any access to the hidden files (started with dot)
|
|
|
|
|
* also, clients can't access any data out the `root` path, that defined on server startup
|
|
|
|
|
|
|
|
|
|
Startup example:
|
|
|
|
|
|
|
|

php src/server.php type=nex host=127.0.0.1 port=1900 root=/target/dir
|
|
|
|
|
```
|
|
|
|
|
|
|
|
