来自PHP的奇怪JSON输出json_encode()

Question

我正在使用PHP玩JSON.我正在使用json_encode()函数来创建JSON.Hovewer我有奇怪的JSON输出:

[

    {
        "0": "1",
        "1": "test",
        "2": "test",
        "ID": "1",
        "title": "test",
        "imageUrl": "test"
    },
    {
        "0": "2",
        "1": "welcome",
        "2": "http://overkiller.pl/Smokopedia/Images/01.jpg",
        "ID": "2",
        "title": "welcome",
        "imageUrl": "http://overkiller.pl/Smokopedia/Images/01.jpg"
    }

]

为什么我得到这种JSON如何从中删除这些数字？我的PHP代码:

<?php
    header('Content-type: application/json');
    $connection = mysql_connect('localhost', 'root', 'sam1');
    $array = array();
    if($connection)
    {
        mysql_select_db("Smokopedia");
        $result = mysql_query("Select * from mainMenu");
        if($result)
        {
            while ($row = mysql_fetch_array($result)) 
            {
                array_push($array, $row);
            }
            echo json_encode($array);
        }else
        {
            $errorJson = array(
                    message => 'Result is empty or incorrect',
                    type => 'error'
                );
            echo json_encode($errorJson);
        }
    }
    mysql_close();

?>

mysql_fetch_array 包括数字索引键和列名索引键.

将其更改为mysql_fetch_assoc,您将获得所需的最终结果.

但请注意,不推荐使用整个mysql扩展,您应该考虑切换到PDO或Mysqli.
