Explanation:
Laravel Blade is a templating engine provided with the Laravel framework. It allows developers to write clean and readable PHP code in their views or templates.
To sum values in a loop using Laravel Blade’s foreach loop, you can follow the below steps:
- Create an array or collection of values.
- Use the foreach loop directive provided by Blade to iterate over the array or collection.
- Inside the loop, add each value to a variable using the += operator to accumulate the sum.
- Display the sum after the loop is finished.
Example:
Let’s say we have an array of numbers [10, 20, 30, 40]. We want to calculate the sum of these numbers using a Laravel Blade foreach loop.
{@verbatim // Controller public function sumExample() { $numbers = [10, 20, 30, 40]; return view('sum-example', compact('numbers')); } // Blade View - sum-example.blade.php@php $sum = 0; @endphp @foreach ($numbers as $number) @php $sum += $number; @endphp @endforeach The sum of numbers is: {{ $sum }}@endverbatim}
In the above example, we declare a variable “$sum” to store the accumulating sum. Inside the foreach loop, we add each number to the “$sum” variable using the “+=” operator. Finally, we display the sum after the loop using Blade’s curly brace syntax “{{ $sum }}”.
When the sumExample() function is called from the controller, it will render the view “sum-example.blade.php” and display the sum of numbers as “The sum of numbers is: 100”.
This is a basic example demonstrating how to calculate the sum using Laravel Blade’s foreach loop. You can apply the same concept to more complex scenarios based on your requirements.
