將'key'和'value'屬性包含到json響應中

查詢數據庫表，獲取數組並寫入json文件。將'key'和'value'屬性包含到json響應中

$sql2 = "SELECT * FROM omharddown ORDER BY id DESC LIMIT 1"; 
$result2 = mysqli_query($dbc, $sql2); 

$json_response = array(); 

while ($row = mysqli_fetch_array($result2, MYSQL_ASSOC)) { 
    $row_array 'key:'['ING_SW_CB'] = $row 'value:'['ING_SW_CB']; 
    $row_array 'key:'['SB_SW_CB'] = $row 'value:'['SB_SW_CB']; 
    $row_array 'key:'['NG3_SW_CB'] = $row 'value:'['NG3_SW_CB']; 
    $row_array 'key:'['Mould_Close'] = $row 'value:'['Mould_Close']; 
    $row_array 'key:'['Leak_Test'] = $row 'value:'['Leak_Test']; 
    $row_array 'key:'['ML_Load'] = $row 'value:'['ML_Load']; 
    $row_array 'key:'['Pre_Heat'] = $row 'value:'['Pre_Heat']; 
    $row_array 'key:'['Dispense'] = $row 'value:'['Dispense']; 
    $row_array 'key:'['A310'] = $row 'value:'['A310']; 
    $row_array 'key:'['Gelation'] = $row 'value:'['Gelation']; 
    $row_array 'key:'['Platen'] = $row 'value:'['Platen']; 
    $row_array 'key:'['Mainline_Unload'] = $row 'value:'['Mainline_Unload']; 
    $row_array 'key:'['De_mould'] = $row 'value:'['De_mould']; 
    $row_array 'key:'['Clean_Up'] = $row 'value:'['Clean_Up']; 
    $row_array 'key:'['Soda_Blast'] = $row 'value:'['Soda_Blast']; 
    $row_array 'key:'['Miscellaneous'] = $row 'value:'['Miscellaneous']; 

    //push the values in the array 
    array_push($json_response,$row_array); 
} 
    //echo json_encode($json_response); 
    $json_data = json_encode($json_response, JSON_PRETTY_PRINT); 
    file_put_contents('your_json_file.json', $json_data);

在JSON文件的輸出是這樣的：

[[{"ING_SW_CB":"5","SB_SW_CB":"3",.........}]]

我所尋找的是：

[[{"key":"ING_SW_CB", "value":"5", "key":"SB_SW_CB", "value":3,....}]]

有誰在那裏有一個解決方案？

我創建了一個使用外部json數據的D3圖表。圖表接受y值，但我需要詳細說明如何在x軸上使用類別名稱。代碼來填充圖表。

barData = [];

d3.json("your_json_file.json", function (data) { 

    for (key in data) { 
     barData.push(data[key].ING_SW_CB) 
     barData.push(data[key].SB_SW_CB) 
     barData.push(data[key].NG3_SW_CB) 
     barData.push(data[key].Mould_Close) 
     barData.push(data[key].Leak_Test) 
     barData.push(data[key].ML_Load) 
     barData.push(data[key].Pre_Heat) 
     barData.push(data[key].Dispense) 
     barData.push(data[key].A310) 
     barData.push(data[key].Gelation) 
     barData.push(data[key].Platen) 
     barData.push(data[key].Mainline_Unload) 
     barData.push(data[key].De_mould) 
     barData.push(data[key].Clean_Up) 
     barData.push(data[key].Soda_Blast) 
     barData.push(data[key].Miscellaneous) 
     // add more .push if needed 
    }

你想要的格式是無效的，因爲你將有多個'key'並在同一個對象，這是不可能的'value'鍵。它需要採用當前格式或者[[{「key」：「ING_SW_CB」，「value」：「5」}，{「key」：「SB_SW_CB」，「value」：3，... 。}]]' – Sean 2015-04-05 15:12:04

爲什麼你想要這種格式的JSON？您正在有效地移除鍵與其值之間的關聯，並計算不同鍵/值對的順序以重新建立鍵。 – dartonw 2015-04-05 15:14:35

我在D3中創建了一個圖表，並需要從外部json文件中填充數據。我見過的最好的例子使用了類似的格式。 – 2015-04-05 15:18:00

所以，如果你的數據是這樣的：

var current_data = [{ 
    "ING_SW_CB": "5", 
    "SB_SW_CB": "3", 
    "NG3_SW_CB": "2", 
    "Mould_Close": "8", 
    "Leak_Test": "6", 
    "ML_Load": "2", 
    "Pre_Heat": "1" 
}]

...您可以使用d3.entries將其轉換爲您在您的評論提到的格式。嘗試：

var formatted_data = d3.entries(current_data[0]);

這會給你：

哇，非常感謝你！ – 2015-04-06 18:21:52

我會在調用外部json文件的函數中使用d3.entries嗎？ – 2015-04-06 18:28:48
