Php 阵列计数误差

我试图从两个键->值过滤器中的以下关联数组中计数，按键性别和键rname，请参见下面

<pre>
Array
(
    [0] => Array
        (
            [fname] => jone
            [lname] => jani
            [gender] => m
            [rname] => N
        )

    [1] => Array
        (
            [fname] => jani
            [lname] => jone
            [gender] => m
            [rname] => N
        )

    [2] => Array
        (
            [fname] => sara
            [lname] => bulbula
            [gender] => w
            [rname] => D
        )

    [3] => Array
        (
            [fname] => hani
            [lname] => hanu
            [gender] => w
            [rname] => P
        )

    [4] => Array
        (
            [fname] => ttttttt
            [lname] => sssssss
            [gender] => m
            [rname] => C
        )

)
</pre>  

排列
(
[0]=>阵列
(
[fname]=>jone
[lname]=>jani
[性别]=>m
[rname]=>N
)
[1] =>阵列
(
[fname]=>jani
[lname]=>jone
[性别]=>m
[rname]=>N
)
[2] =>阵列
(
[fname]=>莎拉
[lname]=>bulbula
[性别]=>w
[rname]=>D
)
[3] =>阵列
(
[fname]=>哈尼族
[lname]=>哈努
[性别]=>w
[rname]=>P
)
[4] =>阵列
(
[fname]=>ttttt
[lname]=>SSS
[性别]=>m
[rname]=>C
)
)

我想要的结果如下

function Array_Counter($Array){
        $Return_Arr = array(
            "M" => array(),
            "F" => array()
        );
    foreach ($Array AS $Arr){
        if ($Arr['gender'] === "m"){
            //Is Male
            @$Return_Arr['M'][$Arr['rname']] ++; // Message supressed due to returning undefined index warnings... Which because of not using isset().. Will still work
        }elseif ($Arr['gender'] === "f"){
            // Is Female
            @$Return_Arr['F'][$Arr['rname']] ++; // Message supressed due to returning undefined index warnings... Which because of not using isset().. Will still work
        }

    }
    return $Return_Arr;

}

 $Array = array (
    array(
        "gender" => "m",
        "rname" => "c"
    ),
    array(
        "gender"=> "f",
        "rname" => "d"
    ),
    array (
        "gender" => "f",
        "rname" => "a"
    ),
        array (
        "gender" => "f",
        "rname" => "x"
    ),
        /* Array shortened for exampling purposes */

);


$Array_Count = Array_Counter($Array);

请帮帮忙

我有一个类似的函数，用于执行与您的请求类似的操作。。因此，这只是一个复制粘贴，因为您已经显示出缺少代码。。这将按预期返回一个数组。。只是在这个返回的数组上进行迭代，这是您需要自己研究的事情

echo "<pre>";
    print_r($Array_Count);
echo "</pre>";

使用以下函数

Array
(
    [M] => Array
        (
            [c] => 1
            [j] => 1
            [g] => 1
            [d] => 1
        )

    [F] => Array
        (
            [d] => 3
            [a] => 1
            [x] => 1
        )

)

我没有看到你的代码，所以我正在尝试制作自己的代码

$arr=array(
排列(
“fname”=>“jone”，
“lname”=>“jani”，
“性别”=>“m”，
“rname”=>“N”
),
排列(
“fname”=>“jani”，
“lname”=>“jone”，
“性别”=>“m”，
“rname”=>“N”
),
排列(
“fname”=>“sara”，
“lname”=>“bulbula”，
“性别”=>“w”，
“rname”=>“D”
),
排列(
“fname”=>“哈尼”，
“lname”=>“哈努”，
“性别”=>“w”，
“rname”=>“P”
),
排列(
“fname”=>“ttttt”，
“lname”=>“SSS”，
“性别”=>“m”，
“rname”=>“C”
),
);
$matrix=array（）；
foreach（数组（'N'，'D'，'P'，'C'，'total'）作为$name）{
foreach（数组（'m'，'w'）作为$gender）{
$matrix[$name][$gender]=0；
}
}
外汇（$arr为$el）{
$matrix[$el['rname'][$el['gender']]+=1；
$matrix['total'][$el['gender']]+=1；
}
回声'；
打印（矩阵）；
回声'；
//或动态键
$matrix=array（）；
外汇（$arr为$el）{
如果（！isset（$matrix[$el['rname']][$el['gender']]））
$matrix[$el['rname'][$el['gender']]=0；
如果（！isset（$matrix['total'][$el['gender']]））
$matrix['total'][$el['gender']]=0；
$matrix[$el['rname'][$el['gender']]+=1；
$matrix['total'][$el['gender']]+=1；
}
回声'；
打印（矩阵）；
回声'；

那么，有错误的代码在哪里？我只能在一个键值中计数……但不能在两个键值中计数。我使用这个小函数，但只能在一个键值中计数。公共函数数组_列（$array，$key）{$field=array（）；foreach（$array as$realKey=>$value）{if（isset（$value[$key]））{$field[$realKey]=$value[$key]；}}返回$field；}您的第一个foreach不会基于rname动态创建计数，例如，如果有一个rname作为

x

引入，会发生什么？您需要修改第一个foreach以接受此论证，这是非常好的解决方案，谢谢。Slawomir先生。
