如何使用按鍵從陣列中獲取價值陣列

Question

我想做

這裏什麼是主陣列

Array 
    (
     [0] => Array 
      (
       [Culture] => Array 
        (
         [id] => 8 
         [title] => test123 
         [description] => test123 
         [year] => 2012 
         [photo] => test123.JPG       
         [datetime] => 0000-00-00 00:00:00 
         [status] => 0 
        ) 

      ) 

     [1] => Array 
      (
       [Culture] => Array 
        (
         [id] => 9 
         [title] => here title 
         [description] => here title 
         [year] => 2012 
         [photo] => here.JPG       
         [datetime] => 0000-00-00 00:00:00 
         [status] => 0 
        ) 

      ) 

     [2] => Array 
      (
       [Culture] => Array 
        (
         [id] => 11 
         [title] => here title 2 
         [description] => here title 2 
         [year] => 2012 
         [photo] => here.JPG       
         [datetime] => 0000-00-00 00:00:00 
         [status] => 0 
        ) 

      ) 

     [3] => Array 
      (
       [Culture] => Array 
        (
         [id] => 12 
         [title] => here title 3 
         [description] => here title 3 
         [year] => 2013 
         [photo] => here.JPG       
         [datetime] => 0000-00-00 00:00:00 
         [status] => 0 
        ) 

      ) 

     [4] => Array 
      (
       [Culture] => Array 
        (
         [id] => 13 
         [title] => here title 4 
         [description] => here title 4 
         [year] => 2014 
         [photo] => here.JPG       
         [datetime] => 0000-00-00 00:00:00 
         [status] => 0 
        ) 

      ) 

     [5] => Array 
      (
       [Culture] => Array 
        (
         [id] => 14 
         [title] => here title 5 
         [description] => here title 5 
         [year] => 2015 
         [photo] => here.JPG       
         [datetime] => 0000-00-00 00:00:00 
         [status] => 0 
        ) 

      )    
    ) 

現在從這個數組我想今年的陣列（通過鍵） 像：

Array 
(
[0]=>2012 
[1]=>2013 
[2]=>2014 
[3]=>2015 
) 

Answer 1

它的工作對我來說

foreach($cultures as $row) 
    { 
     $year[]=$row['Culture']['year']; 
    } 
    $year = array_unique($year); 
    $year = array_values($year); 
    echo "<pre>";print_r($year); 

Answer 2

循環遍歷數組，並將這些年份指定給一個新數組，並且鍵完好無損。

$years=array(); 
foreach($yourArray as $key=>$value) 
{ 
    $years[$key]=$value["Culture"]["year"]; 
} 
$years = array_unique($years); 
print_r($years); 

Answer 3

$years = []; 
foreach($arr as $newarray){ 
    $years[] = $newarray['Culture']['year']; 
} 
$years = array_unique($years); 

新陣列多年來將持有舊陣列中的所有歲月。 array_unique將擺脫所有重複的年份。

Answer 4

您可以通過與foreach循環數組，然後使用array_unique獲得的年數組第一個循環：

$years = array(); 
foreach ($records as $record) { 
    $years[] = $record['Culture']['year']; 
} 
$years = array_unique($years); 

Demo!

Answer 5

我方法是使用array-walk，它使用匿名函數來填充數組，解決方案將僅在一行代碼。
