<?phpnamespace connect_chloe;use PDO;$config = require __DIR__.'\\config\database.php';extract($config);// dsn data source name 包括PDO驱动名称 主机名 端口号 数据库名称$dsn = sprintf('%s:host=%s;port=%d;dbname=%s',$type,$host,$port,$dbname);try{$pdo= new PDO($dsn,$username,$password,[PDO::ATTR_ERRMODE=>PDO::ERRMODE_WARINING]);$pdo->setAtrribute(PDO::ATTR_DEFAULT_FETCH_MODE,PDO::FETCH_ASSOC0);}catch(\Exception $e){die('Connection error:'.$e->getMessage());}?>
三、
<?phpnamespace pdo_chloe;require 'common.php';//接收数据$username = !empty($_POST['username']) && isset($_POST['username']) ? $_POST['username'] :null;$password =!empty($_POST['password']) && isset($_POST['password']) ? $_POST['password'] : null;$gender = !empty($_POST['$gender']) && isset($_POST['$gender']) ? $_POST['$gender'] : null;$create_time = time();//请求分发器 type 1 检查用户名第一名 2 注册 3 登录$type = isset($_POST['type']) && !empty($_POST['type']) ? intval($_POST['type']) : null;switch($type){case 1:$res = checkUname($username);if($res){echo json_encode(['status'=>0,'msg'=>'用户名已被占用'],320);}else{echo json_encode(['status'=>1,'msg'=>'用户名合法'],320);}break;case 2:$sql = "INSERT INTO `user` = '{$username}',`pwd`='{$password}',`gender`={$gender},`create_time`={$create_time};";if(empty($username) || empty($password) || empty($gender)){echo json_encode(['status'=>10,'msg'=>'系统字段错误']);}else{$flag = checkUname($username);if(!$flag){$res = $pdo->exec($sql);if($res){echo json_encode(['status'=>1,'msg'=>'注册成功'],320);}else{echo json_encode(['status'=>0,'msg'=>'注册失败'],320);}}else{echo json_encode(['status'=>0,'msg'=>'请勿重复提交'],320);}}break;default:break;}?>
