Call to a member function toArray() on array -Laravel - php

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) shows the below data. I cannot call $result->toArray(); outside the foreach - it shows the error Undefined variable: result. When declaring $result before foreach as $result=[];, it shows the error Call to a member function toArray() on array. How can i fix it?Can someone tell me how to achieve this? I also tried declaring $result as '' & null before foreach. Both shows errors Call to a member function toArray() on string & Call to a member function toArray() on null respectively.

You are on the right track. You can use the collect() helper to convert the result array into a collection and than you can use the toArray() method.
This is one way to do it:
$result = [];
foreach ($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());
