使用json_encode（）时如何添加空格和换行？ [重复]

This question already has an answer here:

I've seen multiple answers in here but none of them had a solution to my question, so I made an account to ask this question. I understand now that is not an allowed character in json because the backslash is not allowed and that's why the problem is occurring.

I have the following code to encode an array in json:

<?php
$data = array('test1' => 'something1', 'test2' => 'something2', 'test3' => 'something3');
echo json_encode($data);

I'm trying to have the string outputted as follows:

{

"test1": "something1",

"test2": "something2",

"test3": "something3"

}

But what I'm getting is this:

{"test1":"something1","test2":"something2","test3":"something3"}

This is my go at it:

<?php
$data = array('test1' => 'something1
', 'test2' => 'something2
', 'test3' => 'something3
');
echo json_encode($data);

but this returns

{"test1":"something1 ","test2":"something2 ","test3":"something3 "}

</div>

此问题已经存在 这里有一个答案：</ p>

  • 使用PHP漂亮打印JSON 22 answers </ span> < / li> </ ul> </ div>

    我在这里看到了多个答案，但他们都没有解决我的问题，所以我创建了一个帐户 问这个问题。 我现在明白 </ code>不是json中允许的字符，因为不允许使用反斜杠，这就是问题发生的原因。</ p>

    我有以下代码 在json中编码数组：</ p> 

     ＆lt;？php 
 $ data = array（'test1'=＆gt;'something1'，'test2'=＆gt;'something2  '，'test3'=＆gt;'something3'）; 
echo json_encode（$ data）; 
 </ code> </ pre> 
 
 
    我正在尝试输出如下字符串：  </ p> 
 
 
     
 
     {</ p> 
 
 
    “test1”：“something1”，</ p> 
 
 
    “test2”  ：“something2”，</ p> 
 
 
    “test3”：“something3”</ p> 
 
 
    } </ p> 
 </ blockquote> 
 
 < 但是我得到的是：</ p> 
 
 
     
 
     {“test1”：“something1”，“test2”：“something2”，“test3”：“something3  “} </ p> 
 </ blockquote> 
 
 
    这是我的目标：</ p> 
 
 
     ＆lt;？php 
 $ data = array  （'test1'=＆gt;'something1 
'，'test2'=＆gt;'something2 
'，'test3'=＆gt;'something3 
'）; 
echo json_encode（$ data）; 
 </  code> </ pre> 
 
 
    但是返回</ p> 
 
 <block 引用> 
 
     {“test1”：“something1 
”，“test2”：“something2 
”，“test3”：“something3 
”} </ p> 
 </ blockquote> 
  </ DIV>
