Avg ()

The avg method returns the average. All you have to do is pass a key as an argument and the avg method returns the average. You can also use the average method, which is basically an alias for avg.

$avg = collect ([['shoes' = > 10], [' shoes' = > 35], ['shoes' = > 7], [' shoes' = > 68],])-> avg ('shoes')

The above code returns 30, which is the average of all four numbers. If you do not pass any keys to the avg method and all items are numbers, it will return the average of all numbers. If the key is not passed as a parameter and the collection contains key / value pairs, the avg method returns 0.

$avg = collect ([12, 32, 54, 92, 37]); $avg- > avg ()

The above code returns 45.4, which is the average of all five numbers.

You can use these laravel collection methods to work with collections in your own project.
