在多維數組中計數值並將結果保存爲新陣列

這是我的multidim。數組：在多維數組中計數值並將結果保存爲新陣列

Array 
(
    [0] => Array 
     (
      [id] => 1 
      [language] => English 
     ) 

    [1] => Array 
     (
      [id] => 1 
      [language] => English 
     )

      [language] => English 
     ) 

    [19] => Array 
     (
      [id] => 1 
      [language] => English 
     ) 

    [20] => Array 
     (
      [id] => 1 
      [language] => English 
     ) 

    [21] => Array 
     (
      [id] => 1 
      [language] => English 
     ) 

    [22] => Array 
     (
      [id] => 1 
      [language] => English 
     ) 

    [23] => Array

    [25] => Array 
     (
      [id] => 1 
      [language] => German 
     ) 

    [26] => Array 
     (
      [id] => 1 
      [language] => German

    [27] => Array

      [id] => 1 
      [language] => German 
     ) 

    [28] => Array 
     (
      [id] => 1 
      [language] => German 
     ) 

    [29] => Array 
     (
      [id] => 1 
      [language] => German 
     ) 

    [30] => Array

      [id] => 1

     ) 

    [31] => Array 
     (
      [id] => 1 
      [language] => German 
     ) 

    [32] => Array 
     (
      [id] => 1 
      [language] => German 
     ) 

    [33] => Array 
     (
      [id] => 1 
      [language] => German 
     ) 

    [34] => Array 
     (
      [id] => 1 
      [language] => German 
     ) 

    [35] => Array 
     (
      [id] => 1 
      [language] => German 
     ) 

    [36] => Array 
     (
      [id] => 1 
      [language] => German 
     ) 

)

我知道如何通過數組循環，以及如何計算值，但這個時候，我還需要檢查[ID]是否與多國語言的陣列，它有工作的完全動態不同的查詢。

新的陣列應是這樣的：

Array ( 
    [1] => Array(
     "English" => 24, 
     "German" => 12 
    ), 
    [2] => Array(
     "Italian" => 1 
    ) 
)

因此，「*是在一個多種語言的數組* *」你的意思是「*是一個數組的長度大於一個*」？ – Popnoodles

幾乎不適合使用pastebin。把所有必要的東西回答你的問題*在你的問題*。 – meagar

你能告訴你如何計算它們嗎？ – Popnoodles

$sorted_array = array("English" => 0, "German" => 0); 
foreach($old_array as $a) { 
    if(isset($a['language']) && strlen($a['language']) >= 1) { 
     switch($a['language']) { 

     case 'English' : 
      $sorted_array['English']++; 
     break; 
     case 'German' : 
      $sorted_array['German']++; 
     break; 

     } 
    } 
}

只是爲了讓你去......如果你是真正聰明的你可以使用array_keys自動填充您的sorted_array（）爲您...（谷歌它）
