5.7.0
5.11.2
jsonEncode(data)
This operator returns a JSON-encoded UTF-8 version of the data string. The apostrophe (straight single quote), straight double quote, solidus (forward slash) and backslash characters are all escaped by a preceding backslash character. The control characters backspace, form feed, new line, carriage return, horizontal tab are encoded as standard JavaScript escapes (\b, \f, \n, \r\, \t ). Unicode addresses are also escaped: \u2345.
From v5.11.2, the single apostrophe is no longer escaped as this caused some Ajax functions to fail.
For string-type data, see also the '.json' operator.
