在创建JSON时在PHP中使用money_function（）

The following PHP script looks at data from mySQL table and creates string array in JSON.

The two values presented in the array are sumTotal and numvalue.

I would like to format both of these values as currency with the proper decimal placement.

I know that the money_format() function can be implemented somehow but I am having trouble understanding how this could be done.

The following is what I have so far:

if (mysqli_connect_errno()) {
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$sql =  "SELECT name, SUM(value) as numvalue 
         FROM Table1
            LEFT JOIN Table2 USING(DevName)
         WHERE name <> '' 
         and name is not null
         GROUP BY name";

if ($result = mysqli_query($con, $sql)) {

    $resultArray = array();
    $tempArray = array();

    // you want an array of objects, so create an object to sum the sub totals
    $total = new stdClass;
    $total->sumTotal = 0;

    while($row = $result->fetch_object()) {
        $tempArray = $row;
        array_push($resultArray, $tempArray);

        $total->sumTotal = bcadd($total->sumTotal, $row->numvalue);
    }

    $resultArray[] = $total;
    echo json_encode($resultArray);
}

mysqli_close($con);
