1、修改php.ini，打开extension=php_sockets.dll
2、服务端程序SocketServer.php
- <?php
- set_time_limit(0);
- $address = "127.0.0.1";
- $port = 3046;
- $sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) or die("socket_create() fail:" . socket_strerror(socket_last_error()) . "/n");
- socket_set_block($sock) or die("socket_set_block() fail:" . socket_strerror(socket_last_error()) . "/n");
- $result = socket_bind($sock, $address, $port) or die("socket_bind() fail:" . socket_strerror(socket_last_error()) . "/n");
- $result = socket_listen($sock, 4) or die("socket_listen() fail:" . socket_strerror(socket_last_error()) . "/n");
- echo "OK\nBinding the socket on $address:$port ... ";
- echo "OK\nNow ready to accept connections.\nListening on the socket ... \n";
- do {
-
- $msgsock = socket_accept($sock) or die("socket_accept() failed: reason: " . socket_strerror(socket_last_error()) . "/n");
- while(1){
-
- echo "Read client data \n";
-
- $buf = socket_read($msgsock, 8192);
- echo "Received msg: $buf \n";
-
- if($buf == "bye"){
-
- socket_close($msgsock);
- continue;
- }
-
-
- $msg = "welcome \n";
- socket_write($msgsock, $msg, strlen($msg)) or die("socket_write() failed: reason: " . socket_strerror(socket_last_error()) ."/n");
- }
-
- } while (true);
- socket_close($sock);
- ?>
3、客户端程序SocketClient.php
- <?php
- set_time_limit(0);
-
- $host = "127.0.0.1";
- $port = 3046;
- $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)or die("Could not create socket\n");
-
- $connection = socket_connect($socket, $host, $port) or die("Could not connet server\n");
- socket_write($socket, "hello socket") or die("Write failed\n");
- while ($buff = socket_read($socket, 1024, PHP_NORMAL_READ)) {
- echo("Response was:" . $buff . "\n");
- echo("input what you want to say to the server:\n");
- $text = fgets(STDIN);
- socket_write($socket, $text);
- }
- socket_close($socket);
- ?>
4、测试
运行服务端程序：C:\wamp\bin\php\php5.4.16\php.exe
C:\wamp\www\SocketServer.php
运行客户端程序： C:\wamp\bin\php\php5.4.16\php.exe
C:\wamp\www\SocketClient.php
5、其流程与C很相似，实际上就是封装了C的socket。
