如何用键计算数组值

I have array like this i need to count by array values

我有这样的数组我需要按数组值计算

Array ( [Cop] => Array ( [0] => Dozen [1] => Dozen [2] => Akls [3] => Akls ) [MSN] => Array ( [0] => Dozen ) [NeK] => Array ( [0] => Suhan [1] => Ebao ) [NetSE] => Array ( [0] => SuZhan [1] => Guhang ) )

For example

 Array ( [Cop] => Array ( [0] => Dozen [1] => Dozen [2] => Akls [3] => Akls ))

In the Cop key i have two different values for cop so i need cop should be 2

在Cop键我有两个不同的警察值,所以我需要警察应该是2

Cop - 2
MSn - 1
NeK - 2 
NetSE - 2

I need the count like above how can i do this ?

我需要像上面这样的计数我该怎么做?

3 个解决方案

#1

Try simply using array_map,count,& array_unique like as

尝试简单地使用array_map,count和array_unique

array_map(function($v) {
            return count(array_unique($v));
        }, $arr);

#2

Use array_unique() and then count.

使用array_unique()然后计数。

count(array_unique($array['Cop']));// output 2

If you want to print for every key do following:

如果要为每个键打印,请执行以下操作:

$array = array('Cop'=>array('Dozen','Dozen','Akls','Akls'), 'MSN'=> array('Dozen'), 'NeK'=> array('Suhan','Ebao'));
foreach($array as $key => &$value) {
    $value = count(array_unique($array[$key]));
}
print_r($array);

Output:

Cop = 2
MSN = 1
NeK = 2

#3

You should use array_count_values() for that, here's an example:

你应该使用array_count_values(),这是一个例子:

$data = array('cop' => array(0 => 'test', 1 => 'test', 2 => 'test2'));

foreach($data as $item){
    $result = array_count_values($item);
    print_r($result);
}

Outputs:

Array
(
    [test] => 2
    [test2] => 1
)
