PHP: Give a name to an array of JSON objects?
提问by user1739825
I have managed to get data from database in PHP file. From there(data.php),
我已经设法从 PHP 文件中的数据库中获取数据。从那里（data.php），
$output = json_encode($result);
The result would be like this,
结果会是这样
$output=[{"kitty":"Whitely"},{"kitty":"Tabby"},{"kitty":"Ruby"},{"kitty":"Silver"}]
So how do I give name "kitten" an array of kitty objects in php format?
那么如何以 php 格式命名“kitten”一组 kitty 对象呢？
For example like
例如像
"kitten":[{"kitty":"Whitely"},{"kitty":"Tabby"},{"kitty":"Ruby"},{"kitty":"Silver"}]

You have to wrap your result in another array on the 'kitten' key :
您必须将结果包装在 'kitten' 键上的另一个数组中：
$output = json_encode(['kitten' => $result]);

Try this:
尝试这个：
<?php
$kitty = array('kitten' => array());
$kitty['kitty'][] = array('kitty' => 'Tabby');
$kitty['kitty'][] = array('kitty' => 'Ruby');
$kitty['kitty'][] = array('kitty' => 'Silver');
var_dump($kitty);
var_dump(json_encode($kitty));
which results in: {"kitty":[{"kitty":"Tabby"},{"kitty":"Ruby"},{"kitty":"Silver"}]}
这导致： {"kitty":[{"kitty":"Tabby"},{"kitty":"Ruby"},{"kitty":"Silver"}]}

Use nested encodeand decode
使用嵌套encode和decode
$json = '[{"kitty":"Whitely"},{"kitty":"Tabby"},{"kitty":"Ruby"},{"kitty":"Silver"}]';
echo json_encode(array('kitten' => json_decode($json)));
