php - 需要在一个 JSON 中合并多行

Question

如何制作:

 {"color":[{"id":"41","name":"red"}]}
 {"color":[{"id":"19","name":"blue"}]}
 ...

这个东西由 php 和 json_encode 编写

 {"color":[{"id":"41","name":"red"},{"id":"19","name":"blue"},...]}

数据来自数据库，我使用以下代码:

 $json = array();
 $jsonRow= array();
 while ($row = mysqli_fetch_array($getResult)) {
    $jsonRow = array(
        $row['color'] => array(
            array(
                "id" => $row['id'],
                "name" => $row['name'],
            )
        )
    );
    array_push($json,$jsonRow);
 }

Answer 1

 $arr= array();
 $jsonRow= array();
 while ($row = mysqli_fetch_array($getResult)) {
    $jsonRow =  array(
                "id" => $row['id'],
                "name" => $row['name'],
            );
    $arr[]=$jsonRow;
 }
$json = json_encode(array('color'=>$arr));
echo $json;
