Find the sum of one-dimensional arrays using php

In PHP, we can use the array_sum() function to calculate the sum of a one-dimensional array. This function adds all the values ​​in the array and returns their sum.

The following is a sample code that uses the array_sum() function to calculate the sum of a one-dimensional array:

// 创建一个一维数组
$array = array(1, 2, 3, 4, 5);

// 计算数组的总和
$sum = array_sum($array);

echo "数组的总和是：" . $sum;

The output result is:

数组的总和是：15

In addition to using the array_sum() function, we also You can use a for loop or foreach loop to iterate through an array and calculate the sum. The following is a sample code that uses a for loop to calculate the sum of a one-dimensional array:

// 创建一个一维数组
$array = array(1, 2, 3, 4, 5);

// 初始化总和为0
$sum = 0;

// 使用for循环遍历数组并计算总和
for($i = 0; $i < count($array); $i++){
    $sum += $array[$i];
}

echo "数组的总和是：" . $sum;

The output result is:

数组的总和是：15

The foreach loop can also be used to calculate the sum of a one-dimensional array. The following is a sample code:

// 创建一个一维数组
$array = array(1, 2, 3, 4, 5);

// 初始化总和为0
$sum = 0;

// 使用foreach循环遍历数组并计算总和
foreach($array as $value){
    $sum += $value;
}

echo "数组的总和是：" . $sum;

The output result is:

数组的总和是：15

In summary, using the array_sum() function is the simplest and fastest way to calculate the sum of a one-dimensional array, but using a for loop or foreach loop is also A possible approach. Developers can choose the appropriate method according to their actual situation and preferences.
