What is Laravel's similar method to PDO::FETCH_ASSOC? - php

Question

I am updating my php PDO website using Laravel Framework 5.3. I am finding Laravel very easy to use but there are few functions that I don't know the syntax to achieve results.
I have a Laravel controller
public function index(){
$posts = Post::latest()->get();
return view('/home', compact('posts'));
}
which I use in the blade to fetch data using a foreach loop
#foreach ($posts as $row)
#endforeach
which is similar to fetchAll() method in PDO
$row = $posts->fetchAll();
now I want the logic to get fetch(PDO::FETCH_ASSOC) like result, so that I can assign
$row = $posts->fetch(PDO::FETCH_ASSOC);
I have to do this because I want to use for loop in the blade to show the data, if I use foreach loop then it creates duplication for iterated result. Following is the PDO code that I have to update with Laravel
for($i=0; $i<$count_photos; $i++){
$row_gallery = $get_photos->fetch(PDO::FETCH_ASSOC);
$pst_id = $row_gallery['post_id'];
$img = $row_gallery['img_name'];
echo '<div class="img_gallery"><div class="gallery'.$i.'"> <img class="img-responsive" src="uploads/'. $img . '"></div></div>';
}

The models will have already been fetched when you use get() so you'll be able to access the properties on the model straight away e.g.
#foreach ($posts as $post)
{{ $post->title }} //assuming you have a "title" column in the database
#endforeach

Edit
If you have the photos relationship set up in your Post model then you can eager load the relationship. Also, since you only want to load one post you can use first() instead of get() so you would end up with the following:
Controller:
public function index()
{
$post = Post::with('photos')->latest()->first();
return view('/home', compact('post'));
}
Blade file
#foreach($post->photos as $k => $photo)
<div class="img_gallery">
<div class="gallery{{ $k }}">
<a href="{{ url('uploads/'.$photo->img_name) }}" data-lightbox="{{ $post->id }}">
<img class="img-responsive" src="{{ url('uploads/'.$photo->img_name) }}">
</a>
</div>
</div>
#endforeach
