convert php array into single JSON object
提问by chowwy
I converted a PHP array into JSON, using json_encode. I checked the console, and the objects are displaying in array, but as individual objects.
我使用 json_encode 将 PHP 数组转换为 JSON。我检查了控制台，对象显示在数组中，但作为单独的对象。
[ { Object { 03-13-2012="Jazz"}, Object { 07-19-2012="Pop"}, ... ]
How can I convert this array into one object, like this (in PHP or jQuery):
如何将此数组转换为一个对象，如下所示（在 PHP 或 jQuery 中）：
Object { 03-13-2012="Jazz", 07-19-2012="Pop"}
Edit: Here's the beginning of my print_r for the PHP array:
编辑：这是 PHP 数组的 print_r 的开头：
Array
(
[0] => Array
(
[03-13-2012] => Jazz
)
[1] => Array
(
[07-19-2012] => Pop
)
)

Don't be afraid of loops
不要害怕循环
$output = array();
foreach($data as $v) {
$output[key($v)] = current($v);
}
echo json_encode($output, 128);

In general, you need to prepare such a PHP array, which then should be json_encodeand passed along to the server:
一般来说，你需要准备这样一个 PHP 数组，然后它应该是json_encode并传递给服务器：
$data = array(
'03-13-2012' => 'Jazz',
'07-19-2012' => 'Pop',
);
echo json_encode( $data );
exit;

You'll want to iterate over the indexed array making the keys of an associative array found therein into keys in a second associative array.
您需要遍历索引数组，将其中找到的关联数组的键转换为第二个关联数组中的键。
Assumption: You're starting with a JSON string, and you want to end up with a JSON string.
假设：您从一个 JSON 字符串开始，并希望以一个 JSON 字符串结束。
Warning: If you encounter duplicates you will overwrite.
警告：如果您遇到重复项，您将被覆盖。
Here's an example of what I'm talking about:
这是我正在谈论的一个例子：
<?php
$foo = json_decode('[{"abc":"A123"},{"xyz":"B234"}]');
$bar = array();
foreach ($foo as $f) {
foreach ($f as $k => $v) {
$bar[$k] = $v;
}
}
echo json_encode($foo)."\n";
echo json_encode($bar)."\n";
?>
