Introduction to the Average Function in Laravel 11
In Laravel 11, new features have been added, one of which is the function Enumerable::avg(). This function allows us to easily calculate the average of a set of numbers. This feature has made working with data in Laravel much simpler and has reduced the complexity of coding.
Using this function, we can calculate averages with just one line of code. This operation is very intuitive, especially in cases where we deal with statistical or numerical data. For example, if we want to calculate the average prices of products from a vendor, we can easily accomplish this.
Moreover, using Enumerable::avg() allows us to work with a large amount of data without worrying about the complexity of writing our own codes. This capability is one of the necessary tools and standards in programming with Laravel.
In this article, we will examine a simple example of how to use the function avg() and also discuss its challenges and advantages.
Example Code for Using avg()
use Illuminate\Support\Enumerable;
// Assume we have an array of prices
$prices = [100, 200, 300, 400, 500];
// Calculate the average
$average = Enumerable::avg($prices);
// Display the average
echo "Average prices: ".$average;
Line-by-Line Explanation of the Code
use Illuminate\Support\Enumerable;This line allows us access to the
Enumerable class in Laravel. $prices = [100, 200, 300, 400, 500];In this line, we define an array with different prices.
$average = Enumerable::avg($prices);Here, by using the function
avg(), we calculate the average prices and store the result in the variable $average. echo "Average prices: ".$average;In this line, we display the calculated average.
