从SQL查询创建JSON表 [英] Creating JSON table from SQL query

问题描述

我想根据SQL查询的结果创建JSON表.我在phpMyAdmin上尝试了查询，它是正确的(我得到了我想要的数据)，但是当我尝试使用下面的代码将其转换为JSON表时，结果是具有正确结构但表中没有值的表

I want to create a JSON table from the results of a SQL query. I tried the query on phpMyAdmin and it is correct (I get the data that I want) but then when I try to convert it to a JSON table using the code below, the result is a table with the correct structure but non of the values.

/* select all moches from the table moches */
$query="SELECT municipio, SUM(moche) AS moche FROM moches GROUP BY municipio";
$result = $mysqli->query($query);

     $rows = array();
     $table = array();
     $table['cols'] = array(

       array('label' => 'Municipio', 'type' => 'string'),           
       array('label' => 'Cantidad total en moches', 'type' => 'number')

                );

     foreach($result as $r) {

                      $temp = array();

                      //Create the different states

                      $temp[ ] = array('v' => (string) $r['municipio']); 

                      // Total de moches

                      $temp[ ] = array('v' => (int) $r['moche']); 
                      $rows[ ] = array('c' => $temp);


                    }

      $table['rows'] = $rows;

      // convert data into JSON format
      $jsonTable = json_encode($table);
