I have a field in a MySQL database (utf8_general_ci) that contains a curly (smart?) apostrophe: Owner’s...
This prints fine with no special handling if I access the PHP page that pulls it from the DB. However, I am trying to access it via a $.getJSON request on another page, so I used PHP's json_encode. It truncates the value so that it reads Owner, then successfully encodes the rest of the data. If I use PHP's utf8_encode on the field before I json_encode, it includes the full value with the ’ encoded to \u0092 which then doesn't print anything on the page, giving me Owners. PHP's htmlentities and htmlspecialchars have no effect.
Looking at the request in Chrome's tools, Owner’s is shown as Owner�s on the $.getJSON page.
Can anyone help me out here? I have read other questions on SO and the web but I cannot find anything that helps and I haven't worked much with JSON.
Thanks for reading.
The json_encode() function is used to encode a value to JSON format.
JSON data structures are very similar to PHP arrays. PHP has built-in functions to encode and decode JSON data. These functions are json_encode() and json_decode() , respectively. Both functions only works with UTF-8 encoded string data.
The PHP json_encode function translates the data passed to it to a JSON string which can then be output to a JavaScript variable. We demonstrate on this page with single level arrays. Other pages demonstrate using json_encode with multi-dimensional arrays and scalar values.
JSON_UNESCAPED_UNICODE (int) Encode multibyte Unicode characters literally (default is to escape as \uXXXX).
For details: json_encode
Example:
echo json_encode($array, JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP | JSON_UNESCAPED_UNICODE);
Using PHP's utf8_encode() before my json_encode() did indeed stop the data from cutting off after the ’ but it also encoded it to \0092 which did not display (control character). When I used MySQL's SET NAMES utf8 before my query, I did not have to use utf8_encode() at all, and my json was encoded correctly with ’ mapping to \u2019, which displays nicely.
Thanks for the link @Pekka, it helped me narrow down the possibilities.
