Couting各值的出现以阵列 [英] Couting occurrences of each value in an array

问题描述

我想排序和拼接一个数组，但我发现它非常混乱。

I'm trying to sort and splice an array, however I'm finding it very confusing.

我从一个MySQL表拉着我的数据：

I have pulled my data from a mysql table:

$total = mysql_query("SELECT * FROM orders");

我那么每列排序到一个数组：

I am then sorting each column into an array:

while($result = mysql_fetch_assoc($total))
{
 $cst[] = $result['customer'];
 $partnumber[] = $result['partnumber'];
 $misc[] = $result['misc'];
}

现在，杂项有以随机顺序重复的条目例如

now, misc has many entries that repeat in a random order e.g.

$misc = array(
              [0] => red, 
              [1] = >red, 
              [2] => blue, 
              [3] => blue, 
              [4] => blue,
              [5] => green,
              [6] =>red
              )

问：什么是计算在$其它各红色，蓝色或绿色的元素数量的最佳方式？我怎么能创建一个数组，这样 $ misc_num ['红'] = 3 等。

推荐答案

使用的 array_count_values​​ 。
