Laravel Collections Using sum, avg, min or max on a collection for statistical calculations
Example
Collections also provide you with an easy way to do simple statistical calculations.
$books = [
['title' => 'The Pragmatic Programmer', 'price' => 20],
['title' => 'Continuous Delivery', 'price' => 30],
['title' => 'The Clean Coder', 'price' => 10],
]
$min = collect($books)->min('price'); // 10
$max = collect($books)->max('price'); // 30
$avg = collect($books)->avg('price'); // 20
$sum = collect($books)->sum('price'); // 60
