mysocket.php：
<?php class Connector { public static $instance=null; public $conn; private function __construct() { set_time_limit(0); $ip = '192.168.238.1'; $port = 8888; if(($this->conn = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) { echo "socket_create() 失败的原因是:".socket_strerror($this->conn)."\n"; } $result = socket_connect($this->conn, $ip, $port); if ($result < 0) { echo "socket_connect() failed.\nReason: ($result) " . socket_strerror($result) . "\n"; }else { echo "连接OK\n"; } } public static function getInstance() { if(is_null(self::$instance)) { self::$instance = new Connector; } return self::$instance; } public function sendMsg($msg) { socket_write($this->conn,$msg); } public function getMsg() { $clients = array($this->conn); while(true) { $read = $clients; $wrSet = NULL; $errSet = NULL; if(socket_select($read, $wrSet,$errSet, 3) < 1) { continue; } foreach($read as $read_sock) { $data = @socket_read($read_sock,1024,PHP_BINARY_READ); socket_close($this->conn); return $data; } } } } ?>
main.php(调用场所)：
<?php require_once('mysocket.php'); $con = Connector::getInstance(); $req = $_GET['cmd']; $con->sendMsg($req); $ret = $con->getMsg(); echo $ret; ?>
应用说明：
客户端ajax发起请求调用Php，然后php借助socket进一步发起请求给C++模块。
