webman 关于数据库性能
webman链接数据库用的是单例模式 就是用户链接一次 第二次就不需要链接 多个用户就是多个链接1次
public function __construct($pdo, $database = '', $tablePrefix = '', array $config = []) { print_r('测试链接'); $this->pdo = $pdo; // First we will setup the default properties. We keep track of the DB // name we are connected to since it is needed when some reflective // type commands are run such as checking whether a table exists. $this->database = $database; $this->tablePrefix = $tablePrefix; $this->config = $config; // We need to initialize a query grammar and the query post processors // which are both very important parts of the database abstractions // so we initialize these to their default values while starting. $this->useDefaultQueryGrammar(); $this->useDefaultPostProcessor(); }
webman链接redis 也是单例 跟数据库方式一样
public function connect(array $config, array $options) { print_r('测试链接redis'); $connector = function () use ($config, $options) { return $this->createClient(array_merge( $config, $options, Arr::pull($config, 'options', []) )); }; return new PhpRedisConnection($connector(), $connector, $config); }
因为不是携程 不会1个用户会触发2次链接
