php计算多维数组中所有值总和的方法,多维数组

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);

Copy after login

希望本文所述对大家的php程序设计有所帮助。
