计算php

Question

所以我有这个数组：

我不知道是否清楚，但是此数组中有很多elemenst具有相同的名称，我想对这个元素进行计数并显示出来，这就是我创建数组的方式：

 foreach ($rowa as $rowsa)
{
    $sql = "SELECT count(*) as NUMBER FROM BANDZENDINGEN WHERE FB_AFGESLOTEN = 'F' AND FB_AKTIEF = 'T' AND FI_AFVOERKANAAL = 1 AND FI_RAYONID = $rowsa  AND FI_VERRIJKINGID < 1;";
    $sfh = $dbh->prepare($sql);
    $sfh->execute();
    $row = $sfh->fetchAll(PDO::FETCH_COLUMN, 0);

    array_push($row, $rows['FC_RAYON']);
    print_r($row);

}

我已经尝试过：

count of duplicate elements in an array in php

这个答案似乎不适用于我，但也许我做错了事。

btw $ rows ['FC_RAYON']来自另一个查询，与这个问题无关，但是如果您想看到它，我将编辑我的帖子以显示它。

那我该怎么办？你能帮忙吗？

更好地看一下数组：

 Array ( [0] => 2 [1] => RT-SCB-PB01 ) 
 Array ( [0] => 0 [1] => RT-SCB-PB01 ) 
 Array ( [0] => 3 [1] => RT-SCB-PB01 ) 
 Array ( [0] => 1 [1] => ASDC-PBSN ) 
 Array ( [0] => 0 [1] => ASDC-PBSN ) 
 Array ( [0] => 0 [1] => ASDC-PBSN ) 
 Array ( [0] => 0 [1] => ASDC-PBSN ) 
 Array ( [0] => 1 [1] => ASDW-PBSN ) 

这是数组的一小部分。

 Array
(
  [0] => 2
  [1] => RT-SCB-PB01
)

 Array
(
  [0] => 2
  [1] => RT-SCB-PB01
)

Array
(
  [0] => 1
  [1] => RT-SCB-PB01
)

Array
(
  [0] => 3
  [1] => RT-SCB-PB01
)

Array
(
  [0] => 2
  [1] => ASDC-PBSN
)

Array
(
  [0] => 2
  [1] => ASDC-PBSN
)

Array
(
  [0] => 1
  [1] => ASDC-PBSN
)

Array
(
  [0] => 1
  [1] => ASDW-PBSN
)

Array
(
  [0] => 0
  [1] => ASDW-PBSN
)

Array
(
  [0] => 0
  [1] => ASDW-PBSN
)

所以这是对数组的更好的观察，数组中的数据是不同的，因为它是一个非常活跃的数据库

array_count_values

array_count_values（）返回一个数组，该数组使用array的值作为键，并以其在array中的频率作为值。

$varArray = array(); // take a one empty array

foreach ($rowa as $rowsa)
{
    $sql = "SELECT count(*) as NUMBER FROM BANDZENDINGEN WHERE FB_AFGESLOTEN = 'F' AND FB_AKTIEF = 'T' AND FI_AFVOERKANAAL = 1 AND FI_RAYONID = $rowsa  AND FI_VERRIJKINGID < 1;";
    $sfh = $dbh->prepare($sql);
    $sfh->execute();
    $row = $sfh->fetchAll(PDO::FETCH_COLUMN, 0);

    array_push($row, $rows['FC_RAYON']);
    //print_r($row);
    //array_push($varArray,$rows['FC_RAYON']); // Also May I think $rows['FC_RAYON'] is give value like RT-SCB-PB01,ASDC-PBSN etc.
    array_push($varArray,$row[1]); // I have push the send value of array like RT-SCB-PB01,ASDC-PBSN etc. and make in single array.
}

$dupArrays = array_count_values($varArray); // It will return Counts all the values of an array
echo 'Total No Items: '.count($dupArrays).'<br><br>';
echo "<pre>";
print_r($dupArrays);
echo "</pre>";

输出将是：

Total No Items: 3

Array
(
    [RT-SCB-PB01] => 3 // Count of duplicate value of RT-SCB-PB01 is 3
    [ASDC-PBSN] => 4 // Count of duplicate value of ASDC-PBSN is 3
    [ASDW-PBSN] => 1 // Count of duplicate value of ASDW-PBSN is 3
)

使用foreach方法获取

foreach($dupArrays as $key => $value){
    echo $key.' Count '.$value.' times.';
    echo "<br>";
}

输出：

RT-SCB-PB01 Count 3 times.
ASDC-PBSN Count 4 times.
ASDW-PBSN Count 1 times.

您不能只执行一个查询吗？

$sql = "SELECT FI_RAYONID,COUNT(FI_RAYONID) as NUMBER 
    FROM BANDZENDINGEN 
    WHERE FB_AFGESLOTEN = 'F' 
    AND FB_AKTIEF = 'T' 
    AND FI_AFVOERKANAAL = 1  
    AND FI_VERRIJKINGID < 1 
    GROUP BY FI_RAYONID ;";
$sfh = $dbh->prepare($sql);
$sfh->execute();
$result = $sfh->fetch(PDO::FETCH_KEY_PAIR);

然后$ result成为ID和计数的键控数组，因此您可以更轻松地使用它
