bootstrap 4 carousel with Laravel

Laravel’s Blade templating engine’s @foreach control structure directive has $loop variable which is available inside every @foreach loop.

The $loop variable is a stdClass object that provides meta information about the loop you’re currently inside. Take a look at the properties it exposes:

  • index: the index of the current item in the loop; Which starts from 0
  • iteration: the based index of the current item in the loop; Which starts from 1
  • remaining: how many items remain in the loop; if current item is first of five, would return 2
  • count: the count of items in the loop
  • first: boolean; whether this is the first item in the loop
  • last: boolean; whether this is the last item in the loop
  • depth: integer; how many “levels” deep this loop is; returns 1 for a loop, 2 for a loop within a loop, etc.
  • parent: if this loop is within another @foreach loop, returns a reference to the $loop variable for the parent loop item; otherwise returns null
