How to find the sum of even items in an array in php

How to find the even sum of an array in PHP: 1. Define a variable assigned a value of 0 to store the calculation result. The syntax is "$s=0;"; 2. Use the foreach statement to traverse the array. The syntax is "foreach ($array as $value){statement block;}"; 3. In the loop body, determine whether the array element value is divisible by 2, and just add the divisible elements.

How to find the sum of even numbers in an array in php:

1. Define a variable assigned a value of 0 to store the calculation results.

$s=0;

2. Use the foreach statement to traverse the array

foreach ($array as $value){
    语句块;
}

Traverse the given $array array and assign the value of the current array to $value in each loop.

3. In the loop body, perform parity judgment and summation

You only need to judge whether the array element $value is divisible by 2, and add the divisible elements.

if($value%2!=0){
$s += $value;
}

Implementation code:

<?php
header(&#39;content-type:text/html;charset=utf-8&#39;);  
$arr = [1,2,3,4,5,6,7,8,9,10];
var_dump($arr);
$s=0;
foreach($arr as $v){
    if($v%2==0){
        $s+=$v;
    }
}
echo "数组偶数和为：".$s;
?>
