【问题描述】:
// $result=[];
foreach ($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$result->toArray(); - 它显示错误Undefined variable: result。在 foreach 之前将$result 声明为$result=[]; 时,会显示错误Call to a member function toArray() on array。我该如何解决?有人可以告诉我如何实现吗?我还尝试在 foreach 之前将 $result 声明为 '' 和 null。两者都分别显示错误Call to a member function toArray() on string 和Call to a member function toArray() on null。
