is it possible to use foreach in foreach in codeigniter - php

Question

Here is my function - I get an error.
In variable $data['stars'] I got maximum numbers of stars with is invalid
I want correct stars from database because actually stars table are different so that's why.
Is it possible to get stars from another table in this foreach to get accurate value?
public function dbmovies()
{
$this->db->order_by("videos_id", "desc");
$this->db->where(array('publication' => 1, 'is_tvseries' => 0));
$query = $this->db->get('videos');
//get stars
foreach ($query->result() as $key => $value) {
$this->db->where_in('star_id', $value->stars);
$queryStars = $this->db->get('star');
$stars=array();
foreach ($queryStars->result() as $star) {
$stars[] = $star->star_name;
$starone = implode(", ", $stars);
}
$data['videoId'] = $value->videos_id;
$data['imdbid'] = $value->imdbid;
$data['title'] = $value->title;
$data['description'] = $value->description;
$data['duration'] = $value->runtime;
$data['views'] = $value->total_view;
$data['stars'] = $starone;
$alldata[] = $data;
}
$get['data'] = $alldata;
echo json_encode($get, JSON_PRETTY_PRINT);
}
And tge output I get like this
{
"data": [
{
"videoId": "47",
"imdbid": "tt2935510",
"title": "Ad Astra",
"description": "<p>The near future, a time when both hope and hardships drive humanity to look to the stars and beyond.

},
Can anyone please help me?

Answer 1

You have to move the $starone variable to the outside of the foreach loop so that it doesn't get overwritten inside the loop :
foreach ($queryStars->result() as $star) {
$stars[] = $star->star_name;
}
$starone = implode(", ", $stars);

Answer 2

Add empty array before foreach $stars=array();
$stars=array();
foreach ($queryStars->result() as $star) {
$stars[] = $star->star_name;
$starone = implode(", ", $stars);
}
