JSON.encode is adding backslashes

Had to re do this as last question was marked to close as duplicate. BUT the "Duplicate" question was about json decoding not encoding and adding to a file. I have also stated in my question the things I have tried, which as it so happens was the accepted answer on the 'duplicate'.

Please do not mark as duplicate again without actually checking it is.

When I try to create a file with some generated JSON data, the result is like so:

 "{\"1\":{\"title\":\"Sidemen: The Book\",\"ISBN\":\"1473648165\"

as you can see, it has wrapped everything in "" quotes ""

It has also added in lots of: ' \ ' which I don't want.

This is what I currently have:

$json = json_encode($BookList);

and I create the file in PHP like so: 

$fp = fopen($filename, 'w');
fwrite($fp, json_encode($json));
fclose($fp);

I have tried:

$json = json_encode($BookList, JSON_UNESCAPED_SLASHES);

and:

$json = json_encode($BookList, JSON_UNESCAPED_SLASHES);
$json_edited = stripslashes($json);

but nothing seems to be working.

Any ideas?

Update

Book list is generated like so:

$BookList[++$id] = [
    'title'  => (string) $item->ItemAttributes->Title,
    'ISBN'   => '' .(string) $item->ItemAttributes->ISBN
];

You're double-encoding your data, e.g., passing it through json_encode twice. You have

$json = json_encode($BookList, JSON_UNESCAPED_SLASHES);
// -----^^^^^^^^^^^

and also 

fwrite($fp, json_encode($json));
// ---------^^^^^^^^^^^

You only want one of those.
