How to calculate the sum of 10 numbers in a php array

In PHP, multiple values ​​can be easily stored and processed using arrays. Of course, sometimes we need to perform mathematical calculations on the values ​​in the array, such as summation, etc. In this article, we will learn how to calculate the sum of 10 numbers using PHP arrays.

First, we need to create an array containing 10 numbers. You can define this array manually or generate it through some algorithm or external data source. Here, we use manual definition.

$numbers = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);

Next, we need to add all the numbers in the array and store the result in a variable. There is a built-in function array_sum() in PHP that can sum all the values ​​in an array.

$sum = array_sum($numbers);

Now, we have calculated the sum of these 10 numbers and stored it in the $sum variable. We can use this variable to perform further operations, such as outputting the results or saving the results to the database.

echo "数组中的10个数相加的结果是：".$sum;

The output result will be:

数组中的10个数相加的结果是：55

Finally, in order to ensure the readability and maintainability of the code, we'd better add comments so that ourselves or others can make more changes Easily understand how our code works.

The following is the complete sample code:

// 创建包含10个数字的数组
$numbers = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);

// 对数组中的所有数字进行添加操作
$sum = array_sum($numbers);

// 输出结果
echo "数组中的10个数相加的结果是：".$sum;

In short, using PHP arrays for mathematical calculations is very simple and convenient. By combining some built-in array functions, we can easily accomplish the task of array calculations without having to write complex algorithms.
