How to encode multiple MySQLi result into correct json format?

本文关键字：格式 json 编码结果 MySQLi | 更新日期: 2023-09-27

if ($result->num_rows > 0) {
     // output data of each row
     while($row = $result->fetch_assoc()) {
$post_data = array(
    'item' => array(
    'ID' => $row["id"],
    'Name' => $row["name"],
    'Category' => $row["category"],
    'Saldo' => $row["saldo"],
    'Editor' => $row["editor"],
    'Edited' => $row["reg_date"]
  )
);
echo json_encode($post_data);

输出:

{"item":{"ID":"123456","Name":"Chair","Category":"Trashes","Saldo":"40","Editor":"Seppo","Edited":"2015-09-15 13:54:36"}}{"item":{"ID":"123888","Nimi":"Cheese","Kategoria":"Food","Saldo":"3","Editor":"Jorma","Edited:"2015-09-15 14:14:17"}}

当它看起来像这样的时候:

[{"item":{"ID":"123456","Name":"Chair","Category":"Trashes","Saldo":"40","Editor":"Seppo","Edited":"2015-09-15 13:54:36"}},{"item":{"ID":"123888","Nimi":"Cheese","Kategoria":"Food","Saldo":"3","Editor":"Jorma","Edited:"2015-09-15 14:14:17"}}]

不是正确的json格式。我应该如何编辑代码，使我所有的mysql项目通过。

我已经想不出我甚至长时间盯着结果…

您将在每次迭代中重置$post_data。你应该把它加上去。

if ($result->num_rows > 0) 
{
    while($row = $result->fetch_assoc()) 
    {
        $post_data[] = array(
            'item' => array(
                'ID' => $row["id"],
                'Name' => $row["name"],
                'Category' => $row["category"],
                'Saldo' => $row["saldo"],
                'Editor' => $row["editor"],
                'Edited' => $row["reg_date"]
            )
        );
    }
    echo json_encode($post_data);
}
