How to add different values ​​of two arrays in php

php Algorithm for adding different values ​​of two arrays: 1. Get two arrays; 2. Find the different values; 3. Find the sum of the different values; 4. Output the result.

The operating environment of this tutorial: windows10 system, php8.1.3 version, DELL G3 computer.

When developing web applications, we often need to deal with arrays. Sometimes, we may need to calculate the sum of different values ​​in two arrays. This article will introduce how to use PHP language to achieve this function.

1. Obtain two arrays

Before starting the calculation, we first need to obtain two arrays. Arrays can be created using PHP's array declaration syntax, for example:

$array1=array(1,2,3,4,5);
$array2=array(3,4,5,6,7);

2. Find out the different values

In order to find out the different values ​​in two arrays, We can use PHP's built-in functions array_diff(). This function accepts more than two array parameters and returns the value that appears only in the first array.

$diff=array_diff($array1,$array2);

3. Find the sum of different values

Next, we can find the sum of different values ​​by using PHP’s built-in function array_sum(). The array_sum() function returns the sum of all elements in the given array.

$sum=array_sum($diff);

4. Output the results

Finally, we can use the echo statement to output the results. The complete sample code is as follows:

$array1=array(1,2,3,4,5);
$array2=array(3,4,5,6,7);
$diff=array_diff($array1,$array2);
$sum=array_sum($diff);
echo"两个数组中不同的值之和为：".$sum;

Summary:

In this article, we learned how to find the sum of different values ​​in two arrays using PHP language. By using array_diff() function and array_sum() Function, we can conveniently calculate different values ​​and add them together. This technique is very useful for working with arrays and other calculation tasks in programs. I hope it will be helpful to you!
