This code is only for demonstration to show you that you can go up to any level of depth. Now, here is our code in the view using parent to recursively go through the full array. Let’s say we have the following array in the controller that we pass to our view. 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. You can use depth to determine the nesting level of the loop. $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.There are many ways to display data in a table using the foreach method in Laravel. In this post, we’ll look at how to solve the 'Display data in table using foreach in Laravel' programming puzzle. $loop->first Returns true if it is the first iteration or item in the loop else returns false. Display data in table using foreach in Laravel Good day, guys.$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 $foreach loop. In the above example, we first wrap up our foreach loop in an if statement, and by using the isNotEmpty() we check if the collection is empty, and in case that it is empty we then print the No posts found message.Laravel blade has a foreach directive that we can use the same way as we use the foreach loop in PHP. What I would usually do in order to check if a collection is empty in my Blade view is to use an if-else statement like this: foreach ($posts as $post) I want to show that text and I did that while iterating over each text with 'foreach'. If you just need to retrieve a single row from a database table, you may use the DB facade's first method. 5801 8 Laravel Level 1 Kusanagi OP Posted 2 years ago Foreach, variable 'id' for each item Hello, I have a database which contains a lot of text.
