Php 如何使用Yii2查询生成器获取数据

我在尝试什么 我有2个表职员和工资明细，我想取职员姓名和相应的工资

   $salaries = SalaryDetails::find()->select('salary_details.total_salary AS salary,staff.name AS name')
            ->leftJoin("staff",'salary_details.staff_id = staff.id');
        
            


                if ($fcreated_date != null && $tcreated_date != null) {
                    $salaries->andFilterWhere(['>=','salary_details.salary_given_date', $fcreated_date]);   
                    $salaries->andFilterWhere(['<=', 'salary_details.salary_given_date', $tcreated_date]);
                }

我从

salary\u details

中选择了

salary\u details

作为

salary

，

staff

作为

name

作为

salary\u details

左侧加入

staff

关于salary\u details.staff\u id=staff.id 这个查询在phpMyadmin中提供了我想要的数据

但是数组给出了ie，print\r（$salaries）；给予

yii\db\ActiveQuery对象（[sql]=>[on]=>[joinWith]=>[select]=>数组（[0]=>salary\u details.total\u salary AS salary[1]=>staff.name AS name）[selectOption]=>[distinct]=>[from]=>[groupBy]=>[join]=>数组（[0]=>数组（[0]=>LEFT-join[1]=>staff[2]=>salary\u details.staff\u id=>staff.id））[having]=>[union]=>[params]=>Array（）[\u事件：yii\base\Component:private]=>Array（）[\u行为：yii\base\Component:private]=>Array（）[where]=>[limit]=>[offset]=>[orderBy]=>[indexBy]=>[modelsclass]=>common\models\SalaryDetails[with]=>[asArray]=>[multiple]=>[primaryModel]=>[primaryModel]=>[link]=>[via]=>[inverseOf]=>]

谢谢，

正如您在

打印中所看到的，
$salaries
是一个
ActiveQuery
实例。对其调用方法asArray（）->all（）

，以获取记录

$query = SalaryDetails::find()
    ->select('salary_details.total_salary AS salary,staff.name AS name')
    ->leftJoin("staff",'salary_details.staff_id = staff.id');
if ($fcreated_date != null && $tcreated_date != null) {
    $query->andFilterWhere(['>=','salary_details.salary_given_date', $fcreated_date]);   
    $query->andFilterWhere(['<=', 'salary_details.salary_given_date', $tcreated_date]);
}
$salaries = $query->asArray()->all();

$query=SalaryDetails:：find（）
->选择（'salary\u details.total\u salary AS salary，staff.name AS name'）
->leftJoin（“staff”，“salary_details.staff_id=staff.id”）；
如果（$fcreated_date！=null&&$tcreated_date！=null）{
$query->andFilterWhere（['>='，'salary\u details.salary\u given\u date'，$fcreated\u date]）；
$query->andFilterWhere（['
$query = SalaryDetails::find()
    ->select('salary_details.total_salary AS salary,staff.name AS name')
    ->leftJoin("staff",'salary_details.staff_id = staff.id');
if ($fcreated_date != null && $tcreated_date != null) {
    $query->andFilterWhere(['>=','salary_details.salary_given_date', $fcreated_date]);   
    $query->andFilterWhere(['<=', 'salary_details.salary_given_date', $tcreated_date]);
}
$salaries = $query->asArray()->all();
