如何搜索並重置我的後續數組？

Question

Actully array1是我的默認數組。但我提供設施從我的網站購買readingOrder。現在如果一些casino_id 78是購買readingOrder 1比我必須保持在第一position.It實際readingOrder是4. 考慮閱讀=秩和id =賭場_id。

所以基本上array1是我的默認array.array2是購買訂單，我希望結果像這兩個數組array3。

$array1 = Array 
     (
     [0] => Array 
      (
       [id] => 76 
       [readingOrder] => 1 
      ) 

     [1] => Array 
      (
       [id] => 81 
       [readingOrder] => 2 
      ) 

     [2] => Array 
      (
       [id] => 78 
       [readingOrder] => 3 
      ) 

     [3] => Array 
      (
       [id] => 80 
       [readingOrder] => 4 
      ) 

     [4] => Array 
      (
       [id] => 82 
       [readingOrder] => 5 
      ) 

     [5] => Array 
      (
       [id] => 83 
       [readingOrder] => 6 
      ) 

     [6] => Array 
      (
       [id] => 84 
       [readingOrder] => 7 
      ) 

     [7] => Array 
      (
       [id] => 85 
       [readingOrder] => 8 
      ) 

     [8] => Array 
      (
       [id] => 86 
       [readingOrder] => 9 
      ) 

     [9] => Array 
      (
       [id] => 87 
       [readingOrder] => 10 
      ) 

    ) 

塞康陣列： -

$array2 = Array 
(
    [0] => Array 
     (
      [rank] => 1 
      [casino_id] => 78 
     ) 

    [1] => Array 
     (
      [rank] => 4 
      [casino_id] => 76 
     ) 

) 

第三個： -

$array3 = Array 
    (
     [0] => Array 
      (
       [id] => 78 
       [readingOrder] => 1 
      ) 


     [1] => Array 
      (
       [id] => 81 
       [readingOrder] => 2 
      ) 


     [2] => Array 
      (
       [id] => 80 
       [readingOrder] => 3 
      ) 

     [3] => Array 
      (
       [id] => 76 
       [readingOrder] => 4 
      ) 


     [4] => Array 
      (
       [id] => 82 
       [readingOrder] => 5 
      ) 

     [5] => Array 
      (
       [id] => 83 
       [readingOrder] => 6 
      ) 

     [6] => Array 
      (
       [id] => 84 
       [readingOrder] => 7 
      ) 

     [7] => Array 
      (
       [id] => 85 
       [readingOrder] => 8 
      ) 

     [8] => Array 
      (
       [id] => 86 
       [readingOrder] => 9 
      ) 

     [9] => Array 
      (
       [id] => 87 
       [readingOrder] => 10 
      ) 

    ) 

Answer 1

看來，這將工作你的情況與array_combine和array_column的混合物。查看內嵌評論以獲取詳細信息。

// get (rank => casino_id) type array from array2 using array functions. 
$array3 = array_combine(array_column($array2, 'rank'), array_column($array2, 'casino_id')); 
//similar type from array1 
$array4 = array_combine(array_column($array1, 'readingOrder'), array_column($array1, 'id')); 

$temp = $finalArr = array(); 
//push only if the value is present in high priority array (array3). 
foreach ($array4 as $key => $val) { 
    $temp[$key] = $array3[$key] ? $array3[$key] : $array4[$key]; 
} 

//finally modify the array according to original key=> value type. 
foreach ($temp as $k => $v) { 
    $finalArr[] = array(
    'id' => $v, 
    'readingOrder' => $k, 
); 
}
