PHP Socket网络操作类定义与用法示例

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($result) . "n"; }else { echo "连接OKn"; } } public static function getInstance() { if(is_null(self::$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; } } } } ?>
