Decoding multiline string in JSON file using json_decode()

Question

I'm new to JSON so having some trouble parsing it.

I made a JSON file:

newjson.json

{
    "title":"My Title",
    "contents":"My\
                Multiline\
                Contents"
}

I used \ to avoid an error in JavaScript syntax that doesn't allow multiline strings, but when I load it with file_get_contents() and decode it using json_decode() in PHP, it can't parse it.

I think I should handle the \s with preg_replace, or something before I put the string in a decode function.

What should I do?

PHP can't parse your string because it's not valid JSON. The only valid escape sequences are:

\" for a quotation mark
\\ for a backslash
\/ for a forward slash
\b for a backspace
\f for a formfeed
\n for a newline
\r for a carriage return
\t for a tab
\uxxxx for a hexadecimal escape

Use a newline escape instead if you want literal newlines. Otherwise, you'll have to live with a less-pretty string.

{
    "title":"My Title",
    "contents":"My\nMultiline\nContents"
}

Oh, I just wanted to seperate long string contents for readability when writing it. Then isn't that possible? should I have to let it in one line?

@Young-HoKim: Yes, it will have to be in one line.

there must be something wrong in your in json syntax that's why it can't parse it...

try your http://json.parser.online.fr/

copy your whole json string there and try to manipulate that...you may find your error there
