The method for averaging an array in php is: 1. Create a PHP sample file and define an array containing numbers; 2. Use the `array_sum()` function to get the sum of all elements in the array; 3. Use the `count()` function to calculate the number of array elements; 4. Divide the sum of the array by the number of array elements.
Operating system for this tutorial: Windows 10 system, php8.1.3 version, Dell G3 computer.
In PHP, if you want to calculate the average of an array, you need to follow the following steps:
Use the `array_sum()` function to get all the elements in the array Sum.
Use the `count()` function to calculate the number of array elements.
Divide the array sum by the number of array elements to get the average.
The following is a sample code:
<?php //定义一个数组 $array = array(1,2,3,4,5); //通过array_sum()函数求和 $sum = array_sum($array); //通过count()函数获取数组元素的个数 $count = count($array); //根据公式计算平均值 $average = $sum / $count; //输出结果 echo "数组的平均数为: " . $average; ?>
The output result of the above code is:
数组的平均数为: 3
Note: The above code only applies to numeric arrays. For other types of arrays, such as string arrays, data type conversion needs to be performed first.
