I will not introduce what phpsocket is. Below I will give you some examples of communication between the client and the server implemented by phpsocket. I will not introduce anything about php socket. The following describes some examples of communication between the client and the server implemented by php socket.
Script ec (2); script
Server
| The Code is as follows: |
|
Set_time_limit (0 );
$ Host = "localhost ";
$ Port = 1001;
// Create a connection
$ Socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP) or die ("cannot create socketn ");
// Bind the socket to the port
$ Result = socket_bind ($ socket, $ host, $ port) or die ("cannot bind port to socketn ");
// Start listening to this port
$ Result = socket_listen ($ socket, 4) or die ("cocould not set up socket listenn ");
// Accept the connection and use another socket to process the communication
$ Msgsock = socket_accept ($ socket) or die ("cannot accept incoming connectionn ");
If ($ msgsock ){
Echo date ("Y-m-d H: I: s D ");
}
// Read the information sent from the client
$ Input = socket_read ($ msgsock, 1024) or die ("cannot read inputn ");
$ Input = trim ($ input );
$ Output = strrev ($ input). "Reverse Order n ";
// Process the received information and return it to the client
Socket_write ($ msgsock, $ output, strlen ($ output) or die ("cannot write ");
// Close the socket connection
Socket_close ($ msgsock );
Socket_close ($ socket );

Client
| The Code is as follows: |
|
Set_time_limit (0 );
$ Host = "localhost ";
$ Port = 1001;
// Create a socket
$ Socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP) or die ("cannot create socketn ");
$ Conn = socket_connect ($ socket, $ host, $ port) or die ("cannot connect servern ");
If ($ conn) {echo "client connect OK! ";}
Socket_write ($ socket, "hello world! ") Or die (" cannot write datan ");
$ Buffer = fig ($ socket, 1024, PHP_NORMAL_READ );
If ($ buffer ){
Echo "response was:". $ buffer. "n ";
}
Socket_close ($ socket );
