Question

here is my problem:

I want output a formatted array on my webserver, like this:

{
    "status": true,
    "motd": "    [  Mineplex Games  ]    \n        \u2744 New Game \u2744 Gladiators \u2744",
    "version": "1.8",
    "players": {
        "online": 24410,
        "max": 24411
    },
    "ping": "0.039",
    "cache": 1450047242
}

In the source of that page there is not <pre> tag, but I don't know how to reproduce that result without that tag.

How can I do that? Here is my code

  echo '<pre>';
  print_r($array);
  echo '</pre>';

EDIT: echo json_encode($array); will output a non-formatted text, just a line.

Answer 1

您可能想要设置除Note myNote = new Note( txt_Title.getText().toString(), foreignKey, personType, txt_Body.getText().toString() ); tbl_notes.addNewNote(myNote);以外的mime类型。试试text/html（例如，当使用带text/plain的html时）或<pre>（json的官方类型）

在PHP中，使用以下行：

application/json

Answer 2

这是JSON，请尝试echo json_encode($array);

编辑：对于格式化结果，json_encode采用第二个参数。

试试这个echo json_encode($array, JSON_PRETTY_PRINT);

Answer 3

如果您只想在元素之间添加换行符，可以尝试：

echo implode("<br>", $array);

打印没有<pre> tag
