php代码优化---本人的例子

直接上货：

1：数据统计 店铺数量、提现金额、收益金额、用户数量

旧：

// //店铺// $storey = db( 'store' )->whereTime( 'addtime', 'yesterday' )->count();//昨天// $stored = db( 'store' )->whereTime( 'addtime', 'd' )->count();//今天// $storew = db( 'store' )->whereTime( 'addtime', 'w' )->count();//本周// $store = db( 'store' )->whereTime( 'addtime', 'm' )->count();//本月// //收益// $ordery = db( 'order' )->whereTime( 'addtime', 'yesterday' )->sum( 'money' );//昨天// $orderd = db( 'order' )->whereTime( 'addtime', 'd' )->sum( 'money' );//今天// $orderw = db( 'order' )->whereTime( 'addtime', 'w' )->sum( 'money' );//本周// $order = db( 'order' )->whereTime( 'addtime', 'm' )->sum( 'money' );//本月// //提现// $deposity = db( 'deposit' )->whereTime( 'addtime', 'yesterday' )->sum( 'money' );//昨天// $depositd = db( 'deposit' )->whereTime( 'addtime', 'd' )->sum( 'money' );//今天// $depositw = db( 'deposit' )->whereTime( 'addtime', 'w' )->sum( 'money' );//本周// $deposit = db( 'deposit' )->whereTime( 'addtime', 'm' )->sum( 'money' );//本月// //用户// $usery = db( 'userinfo' )->whereTime( 'addtime', 'yesterday' )->count();//昨天// $userd = db( 'userinfo' )->whereTime( 'addtime', 'd' )->count();//今天// $userw = db( 'userinfo' )->whereTime( 'addtime', 'w' )->count();//本周// $user = db( 'userinfo' )->whereTime( 'addtime', 'm' )->count();//本月

新：

$db = null;$data = [];for ( $i = 0; $i < 4; $i++ ) {if ( $i<3 ) {if ( $i == 0 ) {$db = 'store';} else {$db = 'userinfo';}$storey = db( $db )->whereTime( 'addtime', 'yesterday' )->count();//昨天$stored = db( $db )->whereTime( 'addtime', 'd' )->count();//今天$storew = db( $db )->whereTime( 'addtime', 'w' )->count();//本周$store = db( $db )->whereTime( 'addtime', 'm' )->count();//本月$data[ $i ] = ['storey'=>$storey,'stored'=>$stored,'storew'=>$storew,'store'=>$store];} else {if ( $i == 2 ) {$db = 'order';} else {$db = 'deposit';}$storey = db( $db )->whereTime( 'addtime', 'yesterday' )->sum( 'money' );//昨天$stored = db( $db )->whereTime( 'addtime', 'd' )->sum( 'money' );//今天$storew = db( $db )->whereTime( 'addtime', 'w' )->sum( 'money' );//本周$store = db( $db )->whereTime( 'addtime', 'm' )->sum( 'money' );//本月$data[ $i ] = ['storey'=>$storey,'stored'=>$stored,'storew'=>$storew,'store'=>$store];}}

2：where语句 查询token及过期时间

旧：

$list = db('userinfo')->where('token',$tokens)->where('pastdue','>=',$datetime)->count();

新：

$list = db('userinfo')->where("token = '$tokens' and pastdue > '$datetime'")->count();

3：token验证

旧：

 if (!$this->auth->match($this->noNeedLogin)) {//初始化$this->auth->init($token);//检测是否登录if (!$this->auth->isLogin()) {$this->error(__('Please login first'), null, 401);}// 判断是否需要验证权限if (!$this->auth->match($this->noNeedRight)) {// 判断控制器和方法判断是否有对应权限if (!$this->auth->check($path)) {$this->error(__('You have no permission'), null, 403);}}} else {// 如果有传递token才验证是否登录状态if ($token) {$this->auth->init($token);}}

新：

$date = ['imgfile/files','imgfile/list','sekhlp/index','userinfo/index','screen/index','storetype/index','store/index','common/upload'];$type = 1;foreach ($date as $k){if($k==$path){$type = 1;break;}else{$type = 0;}}if($type!==1){}
