finding array index from view in laravel - php

Question

how can I fetch one particular index from the array to delete? e.g. if I have array[a, b, c] in the array list and want to delete b which is index array[1] from it? Any help would be great.
I need to pass index to the controller so I can delete it
View
#foreach (json_decode($p->filename) as $picture)
<ul>
Delete
</ul>
#endforeach
Controller
public function deleteProductImageName($id) {
if(Auth::check()) {
$products = Product::where('id', $id)->first();
foreach($products as $p) {
if(($products->user_id == Auth::user()->id) && ($products->id == $id)) {
$product = Product::where('user_id', Auth::user()->id)
->where('id', $id)->first();
$filename_index = $product->filename;
echo $filename_index; '<br/>';
echo $filename_index . '[' . $index . ']';
}
}
} else {
Session::flash("message", "OOPS! You dont have permission to delete the items. Please login first.");
return redirect("/register-user");
}
}

Have a look at the Loop Variables.
To get the current index, you can use:
$name = $request->query('name');
EDIT
Ok I understand the question better. You want to add additional parameters to the request.
View Example
#foreach($items as $item)
Delete
#endforeach
Controller Example
public function delete($id) {
// get the query parameter
$index = $request->query('index');
}
