You can see in the code below, we have the depth of 3. If you are nested further, you can chain the parent property again to get the $loop variable of the parent of the parent.

Then, you can use parent to get the $loop variable of the parent. Laravel attempts to take the pain out of development by easing common tasks used in most web projects. We believe development must be an enjoyable and creative experience to be truly fulfilling. You can use depth to determine the nesting level of the loop. Laravel is a web application framework with expressive, elegant syntax. $loop->count last element of the get a reference to the parent loop $loop variable when you are in a nested loop. So, you can do something like this in our view file: as first element of the $loop->iteration.

$loop->parentIf this loop is nested within another loop, parent returns the parent’s loop variable If it is not tested, returns null.

$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->last Returns true if it is the last iteration or item in the loop else return false.

$loop->first Returns true if it is the first iteration or item in the loop else returns false.

$loop->count Returns the total number of iterations or the total number of items in the array.

$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->iteration Returns a 1-based current loop iteration 1 would mean the first iteration.

$loop->index Returns a 0-based current loop iteration 0 would mean the first iteration.

$loop variable exposes eight useful properties. The $loop variable is a stdClass object and it provides access to useful meta information about your current loop. directive is more powerful than a normal foreach loop because of the $loop variable that is available inside every $foreach loop. In the above example, we first wrap up our foreach loop in an if statement, and by using the isNotEmpty() we check if the collection is empty, and in case that it is empty we then print the No posts found message.Laravel blade has a foreach directive that we can use the same way as we use the foreach loop in PHP.
