@endforelse

Example 3: forelse blade

{

    $products = Product::get();

    return view('home',compact('products'));

}

<div class="card-header">

    <h5>Laravel Check Array Empty in Blade </h5>

</div>

<div class="card-body">

    @forelse ($products as $product)

        <p class="bg-danger text-white p-1">product</p>

    @empty

        <p class="bg-danger text-white p-1">No product</p>

    @endforelse

</div>

Example 4: $loop laravel list

$loop->index Returns a 0-based current loop iteration; 0 would mean the first iteration
$loop->iteration Returns a 1-based current loop iteration; 1 would mean the first iteration
$loop->remaining Number of iterations remaining in the loop; if there are a total of 10 iterations and the current iteration is 3, it would return 7
$loop->count Returns the total number of iterations or the total number of items in the array
$loop->first Returns true if it is the first iteration or item in the loop else returns false.
$loop->last Returns true if it is the last iteration or item in the loop else return false.
$loop->depth Returns the depth or nesting level of the current loop; returns 2 if it is a loop within a loop and 3 if it is nested one level more
$loop->parentIf this loop is nested within another @foreach loop, parent returns the parent’s loop

Example 5: laravel foreach

public function times(){
    $times = Times::all();
    $bookings = Bookings::all();
    return view('/test2')->with('times', $times)->with('bookings', $bookings);
