How can Nginx or Apache web servers be utilized to handle websocket connections without the need for a PHP proxy?

To handle websocket connections without the need for a PHP proxy, you can configure Nginx or Apache web servers to act as a reverse proxy for websocket connections. This involves setting up a proxy pass directive in the server configuration file to redirect websocket requests to the backend websocket server. By doing this, you can establish a direct connection between the client and the websocket server without the need for PHP to act as an intermediary.

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://backend-websocket-server;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
