PHP Non-blocking Socket with Server-Client Communication: Part 2

Example Code Breakdown
According to PHP manual,
socket_select would run the select() system call on given arrays of sockets with a specified timeout, and wait for them to change status, and return 0 when none of the arrays changes, return 1 when it detects the status change in arrays. Then, I use
socket_read() to see if the server gets a message from the client.
