如何用這組項目創建一個動態數組

Question

array(3) { 
    [0]=> 
    array(4) { 
    ["Field1"]=> 
    string(8) "80000007" 
    ["Field2"]=> 
    string(16) "O70000006" 
    ["Field3"]=> 
    string(0) "" 
    ["Field4"]=>12345 
    string(0) "" 
    } 
    [1]=> 
    array(4) { 
    ["Field1"]=> 
    string(8) "80000008" 
    ["Field2"]=> 
    string(16) "O70000007" 
    ["Field3"]=> 
    string(0) "" 
    ["Field4"]=>78965 
    string(0) "" 
    } 
    [2]=> 
    array(4) { 
    ["Field1"]=> 
    string(8) "80000009" 
    ["Field2"]=> 
    string(16) "H80000006" 
    ["Field3"]=> 
    string(0) "" 
    ["Field4"]=>12345 
    string(0) "" 
    } 
} 

我有上面的數組我想將這些數組項存儲到另一個臨時數組中並使用它。以下是IAM做

$arr_tmp = array(); 
foreach ($result['record'] as $key => $value){ 
       $arr_tmp['Field1'] = $value['Field1']; 
       $arr_tmp['Field2'] = $value['Field2']; 
       $arr_tmp['Field3'] = $value['Field3']; 
       $arr_tmp['Field4'] = $value['Field4']; 
} 

當我盡訴ar_dump($arr_tmp)。 Iam只獲取數組中的最後一條記錄。在使用foreach循環時，我需要在這個$ arr_tmp中設置相同的結果集，以便我可以向該數組添加更多項目。

Answer 1

您只創建了一個arr_tmp數組，並覆蓋每個循環迭代的值。可能你會想要類似的東西：

$arr_tmp[] = array('Field1' => $value['Field1'], 'Field2' => $value['Field2'], etc...) 

而是在循環內。但是，除非我正在讀你的原始數組錯誤，否則這將只是用新的鍵重新創建原始數組，所以這引發了一個問題......爲什麼？這難道不容易嗎：

$arr_tmp = $original_array; 

？

Answer 2

$arr_tmp = array(); 
foreach ($result['record'] as $key => $value){ 
    $cur = array(); 
    $cur['Field1'] = $value['Field1']; 
    $cur['Field2'] = $value['Field2']; 
    $cur['Field3'] = $value['Field3']; 
    $cur['Field4'] = $value['Field4']; 
    $arr_tmp[] = $cur; 
}
