Homephp教程php手册php计算多维数组中所有值总和的方法

这篇文章主要介绍了php计算多维数组中所有值总和的方法,涉及php针对多维数组递归调用的技巧

本文实例讲述了php计算多维数组中所有值总和的方法。分享给大家供大家参考。具体实现方法如下:

php 内置函数 array_sum() 函数返回数组中所有值的总和,只能返回一维数组的总和;

计算多维数组所有值的和就要自定义函数了;

function get_sum($array) { $num = 0; foreach($array as $k => $v) { if(is_array($v)) { $num += get_sum($v); } } return $num + array_sum($array); } get_sum($array);

希望本文所述对大家的php程序设计有所帮助。
