当我们在php中json_encode数组时，我们如何防止添加特殊字符？

Question

主要数组是：

array (size=2)
  0 => 
    array (size=2)
      'message' => string 'Dear subscriber, 
We are working to resolve your link down issue. 
It will take approximately 2-4 hours to fix the issue.We appreciate your cordial support and patience during this time.

Thanks for being with us.
Techno' (length=231)
      'created_at' => string '01:04 pm 11/01/2022' (length=19)
  1 => 
    array (size=2)
      'message' => string 'Dear subscriber, 
We are working to resolve your link down issue. 
It will take approximately 2-4 hours to fix the issue.We appreciate your cordial support and patience during this time.

Thanks for being with us.
Techno' (length=231)
      'created_at' => string '01:04 pm 11/01/2022' (length=19)

在json_encode之后，集合会变成这样(其中包含了我们不想要的额外\n \r )：

'[{"message":"Dear subscriber, \nWe are working to resolve your link down issue. \nIt will take approximately 2-4 hours to fix the issue.We appreciate your cordial support and patience during this time.\n\nThanks for being with us.\nTechno","created_at":"01:04 pm 11\/01\/2022"},{"message":"Dear subscriber, \nWe are working to resolve your link down issue. \nIt will take approximately 2-4 hours to fix the issue.We appreciate your cordial support and patience during this time.\n\nThanks for'... (length=1173)

如果您所需要的只是删除您提到的这两个字符(基本上是新行)，您可以在json_encode $result上尝试这样的操作：

$result = str_replace("\\n", '', $result);

$result = str_replace("\\r", '', $result);

例如，您可以找到更多的here选项。
