PHP获取上月数据及当月数据

PHP获取上月数据及当月数据

1.获取上个月第一天及最后一天
echo date(‘Y-m-01’, strtotime(’-1 month’));
echo date(‘Y-m-t’, strtotime(’-1 month’));

2.获取当月第一天及最后一天
$BeginDate=date(‘Y-m-01’, strtotime(date(“Y-m-d”)));
echo $BeginDate;echodate{(}^{\prime }Y-m-d^{\prime },strtotime("$BeginDate +1 month -1 day"));

3.使用函数及数组来获取上月数据并更新数据库成本月数据（只提取上月数据）
public function actionViewlist()
{
$time = date(‘Y-m-01’,strtotime(’-1 month’));
$times=strtotime($time);
$lasttime = date(‘Y-m-t’,strtotime(’-1 month’));
$lasttimes=strtotime($lasttime);
$selectModel = $this->modelClass::find()->join{(}^{\prime }joi{n}^{\prime }{,}^{\prime }r{f}_h{b}_{l}edge{r}_{f}iles{b}^{\prime }{,}^{\prime }b.id=r{f}_h{b}_{l}edge{r}_{p}ro.ledge{r}_i{d}^{\prime })->select{(}^{\prime }r{f}_h{b}_{l}edge{r}_{p}ro.{\ast }^{\prime })->where({[}^{\prime }{<}^{\prime }{,}^{\prime }r{f}_h{b}_{l}edge{r}_{p}ro.create{d}_a{t}^{\prime },strtotime(date("Y-m-1",time()))])->andWhere({[}^{\prime }{>}^{\prime }{,}^{\prime }dat{e}^{\prime },$times])
->andWhere([’<’,‘date’,$lasttimes])
->asArray()
->all();
$no{w}_{t}ime=strtotime(date{(}^{\prime }Y-m-d^{\prime },time()));foreach($selectModel as &KaTeX parse error: Expected '}', got 'EOF' at end of input: … unset(v[‘id’]);
$v[‘created_at’] = $v[‘updated_at’] = $now_time;
}
$feild=arra{y}_{k}eys($selectModel[0]);
// ->db->createCommand()->insert()->execute();
KaTeX parse error: Undefined control sequence: \Yii at position 10: insert = \̲Y̲i̲i̲::app->db->createCommand()->batchInsert(HbLedgerPro::tableName(),$feild,$selectModel)->execute();
return $insert;
}
