In php, you can use array_sum() function and " " operator to implement the sum of multiple arrays.

Implementation steps:

Step 1: Use the array_sum() function to find the sum of the elements in multiple arrays

array_sum() is a built-in function in PHP that can calculate the sum of all elements in an array and return the sum of the elements.

$sum1=array_sum($arr1);
$sum2=array_sum($arr2);
$sum3=array_sum($arr3);
$sum4=array_sum($arr4);
...
$sumN=array_sum($arrN);

Step 2: Use the " " operator to add the sum of the obtained elements to find the sum of multiple arrays

$sum = $sum1 + $sum2 + $sum3 + $sum4 +....+ $sumN;

Implementation example:

<?php
header("Content-type:text/html;charset=utf-8");
$arr1 = array(1,2,3,4,5);
$arr2 = array(6,7,8,9,10);
$arr3 = array(1,3,5,7,9);
$arr4 = array(2,4,6,9,10);

$sum1=array_sum($arr1);
echo &#39;$arr1的元素总和：&#39;.$sum1;
$sum2=array_sum($arr2);
echo &#39;<br>$arr2的元素总和：&#39;.$sum2;
$sum3=array_sum($arr3);
echo &#39;<br>$arr3的元素总和：&#39;.$sum3;
$sum4=array_sum($arr4);
echo &#39;<br>$arr4的元素总和：&#39;.$sum4;

$sum = $sum1 + $sum2 + $sum3 + $sum4;

echo &#39;<br>多个数组的总和：&#39;.$sum;
?>
