<?php session_start(); class DB{ private static $car; //私有静态变量; private $redis; //静态变量 private function __construct(){ $this->redis = new Redis(); $this->redis->connect('127.0.0.1','6379'); } private function __clone(){ //防止克隆 } public static function test(){ //检测有没有实例化本身; if(!self::$car instanceof self){ return $car=new self; } return self::$car; } public function tat($ar){ } } $arr=DB::test()->tat(5);
