php - How to use nl2br to remove \n and add breaks -

There is a problem getting me nl2br to do everything I need to do .

Can anyone explain that nl2br is passed to \ n in JSON data by & lt; Br / & gt; In my PHP?

Here is the code:

  $ page = file_get_contents ('JSON_FEED_URL'); $ Page2 = nl2br ($ page);   
 When I resonate  $ page2  and look at the HTML page, it comes in the form of a large wall of text.   
 
 
 Try  
  $ page = file_get_contents ('JSON_FEED_URL') ; $ Page2 = preg_replace ("/ \\ n / m", "
  
 As stated,  str_replace  works even faster, but the number above the multipurpose brake.
