Php 这个json怎么会无效？

实际上，我对这个json是如何无效感到困惑。我有一个更大的json集合中的json片段：

               ...
               "open_until":{  
                  "date":"2015-10-16 00:00:00",
                  "timezone_type":3,
                  "timezone":"America\/Edmonton"
               },
               "ffba_access_code":"1234",
               "overview_content":" 
Elevator Pitch<\/h4>\r\n 
Fedilus Funds gives investors the ability to participate in the growth of the United States un-banked sector by deploying 'automated commerce machines' in high traffic areas. This is a blended investment that distributes monthly principal and interest back to the investor and once the term has ended, a percentage of revenue is distributed continuously. You are purchasing a portfolio of advanced ATM's that offer a wide range of financial services coupled with a strong management team.<\/p>\r\n\r\n 

This is a USD investment with monthly distributions remitted in USD.<\/p>",
               .....

当我将其通过json格式化程序时，我被告知：

" 
    Elevator Pitch<\/h4>\r\n 
    Fedilus Funds gives investors the ability to participate in the growth of the United States un-banked sector by deploying 'automated commerce machines' in high traffic areas. This is a blended investment that distributes monthly principal and interest back to the investor and once the term has ended, a percentage of revenue is distributed continuously. You are purchasing a portfolio of advanced ATM's that offer a wide range of financial services coupled with a strong management team.<\/p>\r\n\r\n 

    This is a USD investment with monthly distributions remitted in USD.<\/p>"

这是无效的令人讨厌的佩斯吗

我可以从php中的数据库中找到这个。当我将此特定数据库字段拉出以使其符合要求时，是否应该对其执行某些操作？

出于此原因，属性值或属性中不能有换行符

这个例子很好：

...
"open_until": {
  "date": "2015-10-16 00:00:00",
  "timezone_type": 3,
  "timezone": "America/Edmonton"
},
"ffba_access_code": "1234",
"overview_content": "Elevator Pitch</h4>\r\n Fedilus Funds gives investors the ability to participate in the growth of the United States un-banked sector by deploying 'automated commerce machines' in high traffic areas. This is a blended investment that distributes monthly principal and interest back to the investor and once the term has ended, a percentage of revenue is distributed continuously. You are purchasing a portfolio of advanced ATM's that offer a wide range of financial services coupled with a strong management team.</p>\r\n\r\n This is a USD investment with monthly distributions remitted in USD.</p>"

JSON不允许真正的换行符。您需要将所有换行符替换为\n。

正如一些人指出的那样，将数据库中的内容包装起来是解决问题的诀窍。

关于需要转义的换行符，上面的答案是正确的。查看php的内置json_encode函数

此外，这个答案还有一些关于换行符和转义反斜杠的有用信息：

您是否尝试在概述内容文本中使用htmlspecialchars？如果我没记错，换行符无效…@Andre So sicne我从数据库中提取了数据，如何使其有效？通过。让我反过来问这个问题：你为什么要手动编码？@Andre:你没记错：换行符是一个控制字符。@VolkerK嗯，我对数据库中的内容进行了编码你是说问题中显示的错误json已经存在于数据库中；你是从text/varchar字段中提取的吗？在这种情况下：是什么将无效的enocded not json放在数据库中？无论如何，不会对换行符/换行符执行任何操作。此函数处理的字符为&、，
