php - 如何使用php将第二个数组值插入第一个数组

Question

我有第三方供应商提供的多维数组，详细信息如下。

$数据 = 数组 (
    “学生数据” => 数组（
        大批（
            “大学” => 数组（

            ),
        )
    ),
);

我必须根据场景中的“lessonData”标签中的每个“lessonIdNumber”修改上述数组的结果：将[sessionName]和[teacherData]的值从[lessonData]移到[studentData]数组中的每个[lesson]下面[课程编号]。

我希望我的问题很清楚并得到解决。谢谢您的帮助。

Answer 1

这可以满足您的要求...

$lessonData  = $data['lessonData'];
$studentData = $data['studentData'];

$lessons = array();

foreach ($lessonData as $lessonDat)
{
    $lessons[$lessonDat['lessonId']['lessonIdNumber']] = $lessonDat;
}

foreach ($studentData as $id=>$studentDat) {

    $studentData[$id]['sessionName'] = $lessons[$studentDat['lesson']['lessonId']['lessonIdNumber']]['sessionName'];
    $studentData[$id]['teacherData'] = $lessons[$studentDat['lesson']['lessonId']['lessonIdNumber']]['teacherData'];
}

unset($data['lessonData']);

我当然希望这是为了工作而不是编码任务。对于新手程序员来说，这是一项非常具有挑战性的任务，但听起来像是一项很棒的学校作业。

如果是这样，我建议您只使用它来检查您的工作，否则我希望它会有所帮助。祝你好运！

Answer 2

另一种方法是最初将课程编号映射到课程数据。让我们像这样尝试，

$student = $data['studentData'];
$lesson = $data['lessonData'];
$expected = [];

# mapping the lession id to lession data e.g 40=>[sessionName=>'Coreldraw','teacherData'=>[array]]
foreach($lesson as $key=>$value){
    $mapped[$value['lessonId']['lessonIdNumber']] = ['sessionName'=>$value['sessionName'],'teacherData'=>$value['teacherData']];
}

foreach($student as $k=>$v){
    $lesson_id = $v['lesson']['lessonId']['lessonIdNumber'];
    if(array_key_exists($lesson_id, $mapped)){
        $expected['studentData'][$k] = array_merge($student[$k], $mapped[$lesson_id]);
    }
}

print_r($expected);
