如何將數組索引鍵更改爲MySQL值

Question

我需要使用數組的幫助。我有一個來自MySQL查詢的數據。在for循環中打印後，我得到以下array_flip：

Array ( 

    [Duru 60] => 0 
    [Maxwell 50] => 1 
    [Fashanu 70] => 2 
    [Nwankwo 80] => 3 
    [Obi 0] => 4 

    ) 

數組值是2個字段名稱和總分的組合。我想實現的是一個數組，像這樣：

Array (

    [Duru 60] => 60 
    [Maxwell 50] => 50 
    [Fashanu 70] => 70 
    [Nwankwo 80] => 80 
    [Obi 0] => 0 

    ) 

我想實現的是默認的陣列數字鍵（0,1,2,3,4）更改爲從查詢得到的總分數。

這裏是給第一陣列塊中的代碼：

PHP代碼開始

$dataA = array(); 

    foreach($data as $key => $val){ 

$dataC = $val['lastname']." ".$val['total']; 
array_push($dataA,($dataC)); 

    } 
    $dataD = (array_flip($dataA)); 

    print_r($dataD); 

Answer 1

$dataA = array(); 
foreach($data as $key => $val){ 
    $dataK = $val['lastname']." ".$val['total']; 
    $dataV = $val['total']; 
    $dataA[$dataK] = $dataV; 
} 
print_r($dataA); 

Answer 2

試試這個：

$dataA = array(); 

    foreach($data as $key => $val){ 

      $dataC = $val['lastname']." ".$val['total']; 

      $dataA[$dataC] = $val['total']; 

    } 

    print_r($dataA); 

Answer 3

爲什麼你不能只是做：

$newData = array(); 
foreach($data as $key => $val) { 
    $newData[$val['lastname'] . ' ' . $val['total']] = $val['total']; 
} 
print_r($newData);
