Format echo json_encode
提问by Craig Weston
I would like to format the echo json_encode, the output is currently
我想格式化 echo json_encode，输出是当前
{"results":{"course":"CC140","books":{"book":[[{"id":"300862","title":"Building object-oriented software","isbn":"0070431965","borrowedcount":"6"}]]}}}
Whereas i would like to to output like this:
而我想像这样输出：
{
"results": {
"course": "CC140",
"books": {
"book": [
[
{
"id": "300862",
"title": "Building object-oriented software",
"isbn": "0070431965",
"borrowedcount": "6"
}
]
]
}
}
}
This is the code that makes the JSON
这是生成 JSON 的代码
$temp = array();
foreach ($my_array as $counter => $bc) {
$temp['id'] = "$id[$counter]";
$temp['title'] = "$title[$counter]";
$temp['isbn'] = "$isbn[$counter]";
$temp['borrowedcount'] = "$borrowedcount[$counter]";
$t2[] = $temp;
}
$data = array(
"results" => array(
"course" => "$cc",
"books" => array(
"book" =>
array(
$t2
)
)
)
);
echo json_encode($data);
Any help or pointers would be appreciated, thanks
任何帮助或指示将不胜感激，谢谢
Adding this
添加这个
header('Content-type: application/json');
echo json_encode($data, JSON_PRETTY_PRINT);
formats the JSON, but the header also outs the entire HTML document
格式化 JSON，但标题也超出整个 HTML 文档

The first piece of advice I'd give is: Don't. JSON is a data format. Deal with it using tools rather then trying to have your server format it.
我给出的第一条建议是：不要。JSON 是一种数据格式。使用工具处理它，而不是尝试让您的服务器对其进行格式化。
If you are going to ignore that, then see the manual for the json_encodefunctionwhere it gives a list of optionswhich includes JSON_PRETTY_PRINTwhich is described as Use whitespace in returned data to format it. Available since PHP 5.4.0.
如果您要忽略它，请参阅该json_encode函数的手册，其中提供了一个选项列表，其中包括JSON_PRETTY_PRINT被描述为在返回的数据中使用空格对其进行格式化的选项。自 PHP 5.4.0 起可用。
Thus the steps are:
因此步骤是：
- Make sure you are using PHP 5.4.0 or newer
json_encode($data, JSON_PRETTY_PRINT);
- 确保您使用的是 PHP 5.4.0 或更新版本
json_encode($data, JSON_PRETTY_PRINT);

You can use json_encode($data, JSON_PRETTY_PRINT)in php 5.4+
您可以json_encode($data, JSON_PRETTY_PRINT)在 php 5.4+ 中使用
In php 5.3 & under that, you could try formatting it with regular expressions, but it's not too safe (or you could use library for encoding json).
在 php 5.3 & 下，您可以尝试使用正则表达式对其进行格式化，但这不太安全（或者您可以使用库来编码 json）。
