对数组上的成员函数toArray()的调用-Laravel

Question

// $result=[];
foreach ($chapter['chapter_content'] as $row) {
$result = CoursePublishChaptercontent::create([
'courseId' => $postdata[$i]['courseId'],
'course_chapter_id' => $postdata[$i]['course_chapter_id'],
'file_id' => $postdata[$i]['file_id'],
'course_chapter_content_id' => $postdata[$i]['course_chapter_content_id'],
]);
}
dd($result->toArray());

dd($result)显示了以下数据。我不能在foreach之外调用$result->toArray();-它显示错误Undefined variable: result。在foreach之前声明$result为$result=[];时，它显示错误Call to a member function toArray() on array。我该怎么修？有人能告诉我如何做到这一点吗？我还尝试将CCD_ 8声明为CCD_；CCD_ 10。两者都显示错误Call to a member function toArray() on string&CCD_ 12。

你走在了正确的轨道上。您可以使用collect()帮助器将结果数组转换为集合，然后使用toArray()方法。这是一种方法：

$result = [];
foreach ($chapter['chapter_content'] as $row) {
$result[] = CoursePublishChaptercontent::create([
'courseId' => $postdata[$i]['courseId'],
'course_chapter_id' => $postdata[$i]['course_chapter_id'],
'file_id' => $postdata[$i]['file_id'],
'course_chapter_content_id' => $postdata[$i]['course_chapter_content_id'],
]);
}
dd(collect($result)->toArray());
