从数组计数值 [英] Counting values from an array

问题描述

我想计数一个数组内的所有值，我试过使用count（）但没有效果，数组值也可能有负数，例如：

 数组
（
 [name] => 1 
 [phone] => 1 
 [emailX] => 1 
 [car] => 0 
 [finance] => 2 
 [employed] => 1 
 [credit] => -5 
）
  

如果将它们全部统计在一起，结果应为1，你可以使用 .net / array_sumrel =nofollow noreferrer> array_sum（）：

  $ sum = array_sum myArray）; 
  

count（）函数给出了数组中的项数。

I'm trying to count all the values inside an array, I've tried using count() but to no avail, the array values may also have negatives in them, example:

Array
(
    [name] => 1
    [phone] => 1
    [emailX] => 1
    [car] => 0
    [finance] => 2
    [employed] => 1
    [credit] => -5
)

If you count all of them together, the result should be 1, I'm just not sure how to go about it.. :/

解决方案

You can use array_sum():

$sum = array_sum($myArray);

The count() function gives you the number of items in the array.
