jsonでループ応答を作成する方法は？

Question

table.service_master_new,table.department_masterおよびtable.document_masterの3つのテーブルからデータをフェッチしています。

テーブル構造：

テーブルで

データ：

とデータをフェッチするための私のPHPコードは次のとおりです。

<?php 
include 'mysql.php'; 
$matrix = array(); 
$getServices = mysqli_query($db,"SELECT * FROM service_master_new"); 
while($row=mysqli_fetch_array($getServices,MYSQLI_ASSOC)){ 
    $xmatrix = array(); 
    $dept_code = $row['dept_code']; 
      $getDeptName = mysqli_query($db,"SELECT * FROM department_master WHERE Dept_Code='$dept_code'"); 
      while($row1 = mysqli_fetch_array($getDeptName,MYSQLI_ASSOC)){ 
       $xxmatrix = array(); 
       $dept_name = $row1['Dept_Name']; 
       $xmatrix['dept_name'] = $dept_name; 
       array_push($xmatrix, $dept_name); 

       $service_name = $row['service_name']; 
       $xmatrix['service_name'] = $service_name; 
       array_push($xmatrix, $service_name); 
       $contact_point = $row['contact_point']; 
       $xmatrix['contact_point'] = $contact_point; 
       array_push($xmatrix, $contact_point); 
       $timeline = $row['timeline']; 
       $xmatrix['timeline'] = $timeline; 
       array_push($xmatrix, $timeline); 

       $doc_codes = $row['doc_codes']; 
       $xdocs = array(); 
       $codes = explode(",",$doc_codes); 
       $countCodes = count($codes); 
       for($i=0;$i<$countCodes;$i++){ 
        $getDocs = mysqli_query($db,"SELECT * FROM document_master WHERE Doc_Code='$codes[$i]'"); 
        while($row4 = mysqli_fetch_array($getDocs,MYSQLI_ASSOC)){ 
         $doc_name = $row4['Doc_Name']; 
         array_push($xdocs, $doc_name); 
        } 
        $xmatrix['docs'] = $xdocs; 
       } 
     } 


    array_push($matrix, $xmatrix); 
} 
echo json_encode($matrix); 
?>

しかし、私はデータになりたいです彼らの部署によって整理された：

電気部門は二度来るべきではありません。それは電気部門内の別の配列になければなりません。

Answer 1

サンプルコードを追加しています。自分で修正してください。

3つの異なるテーブルがあり、これらのテーブルからデータをフェッチしてjson出力にする必要があります。ここでのコード例：

foreach ($table_one as $to) { 

    foreach($table_two as $tt) { 

     foreach($table_three as $ttr) { 

     $data[]  = array 
     (
     'value1' => $ttr['value1'], 
     'value2' => $tt['value2'], 
     'value3' => $to['value3'] 
     ); 
     } 
    } 
} 

$json = json_encode($data); 

これは単なる例に過ぎません。あなた自身でそれを変更することを忘れないでください！
