Find the sum of elements in an array using the array_sum() function in PHP

Title: Use the array_sum() function in PHP to find the sum of array elements

PHP is a widely used server-side scripting language that provides many Built-in functions to simplify the development process and improve efficiency. Among them, the array_sum() function is a very practical function that can be used to calculate the sum of elements in an array. In this article, we will learn how to use the array_sum() function and give specific code examples.

First of all, we need to understand how to use the array_sum() function. This function accepts an array as argument and returns the sum of all elements in the array. The following is the basic syntax of the array_sum() function:

array_sum(array $array): number

Among them, $array is the array to be calculated, and number is the result of the sum. It should be noted that $array must be an indexed array, otherwise 0 will be returned.

Next, in order to better understand the use of the array_sum() function, we give a specific code example.

<?php
// 定义一个示例数组
$numbers = array(1, 2, 3, 4, 5);

// 使用array_sum()函数计算数组元素的总和
$total = array_sum($numbers);

// 输出结果
echo "数组元素的总和为： " . $total;
?>

In the above code, we define an array named $numbers, which contains some integer elements. We calculated the sum of the elements in the array by calling the array_sum() function and passing $numbers as argument and stored the result in the $total variable. Finally, we use the echo statement to output the results to the browser.

Run the above code, you will get the following output:

数组元素的总和为： 15

As you can see from the above output, we successfully used the array_sum() function to calculate the sum of the array elements and display the result on the page.

To summarize, using the array_sum() function in PHP can quickly and easily calculate the sum of the elements in an array. Whether for working with a set of numbers or for other situations where summing is required, this function provides a simple and effective solution. By rationally utilizing the array_sum() function, we can simplify the code and improve development efficiency. I hope this article will help you understand and apply the array_sum() function.
