You do not want to delete it  Because JSON uses double quotes     for strings  and your one returns        output    append    This is a test  lt   p gt        these backslashes escape these quotes

I just figured out that json encode does only escape  n if it s used within single quotes   echo json encode  Hello World n       results in  Hello World n    And  echo json encode  Hello World n       results in  Hello World   n

the solution that does work is this    str   preg replace                 str     However you have to be extremely careful here because you need to make sure that all your values have their quotes escaped  which is generally true anyway  but especially so now that you will be stripping all the escapes from PHP s idiotic  and dysfunctional   helper  functionality of adding unnecessary backslashes in front of all your object ids and values    So  php  by default  double escapes your values that have a quote in them  so if you have a value of My name is  Joe  in your DB  php will bring this back as  My name is    Joe      This may or may not be useful to you  If it s not you can then take the extra step of replacing the leading slash there like this    str   preg replace                   str     yeah    it s ugly    but it works    You re then left with something that vaguely resembles actual JSON
