Question

我从3个表中获取数据：table.service_master_new，table.department_master和table.document_master。

表格结构：

表格中的数据：

我的用于获取数据的php代码是：

<?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);
?>

但我希望数据由他们的部门安排，例如：

电力部门不应该两次;它应该在电力部门内的另一个阵列中。

Answer 1

我只是添加一些示例代码，请自行修改。

假设我们有3个不同的表，我们应该从这些表中获取数据并使其成为json输出。这是一个示例代码：

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);

请记住，这只是一个例子。别忘了为自己修改它！

如何在json中创建循环响应？
