This is what the server does. It initializes the socket and the buffer that you use to receive
and send data. Then it waits for a connection. Once a connection is created it prints
\u201cSocket connected\u201d to the screen the server is running on. The server then checks to see if
there is anything in the buffer; if there is, it sends the data to the connected computer.
After it sends the data it waits to receive information. Once it receives information it stores
it in the data, lets the connected computer know that it has received the information, and
then closes the connection. After the connection is closed, the server starts the whole
process again.

To solve the second problem is very easy. You need to create a PHP page that connects to
a socket, receive any data that is in the buffer, and process it. After you have processed the
data in the buffer you can send your data to the server. When another client connects, it
will process the data you sent and the client will send more data back to the server.
