Zend_JSON:Encode messing up - why?
13,516
Solution 1
You fix this by updating your PHP version to a version later than version 5.2.7.
There was a serious UTF-8 bug in PHP's json_encode function before that version. See the changelog for more details.
Since you note that you are using PHP version 5.2.9.2 your version should be good :) Have you tried routing the specific contents of the html through PHP's json_encode() manually?
Or maybe through utf8_encode() or utf8_decode()?
Solution 2
I see only one possible area where NULL may be returned from Encoder.php. I'd begin debugging by doing some var_dumps inside this function in Zend/Json/Encoder.php
protected function _encodeDatum(&$value)
{
$result = 'null';
if (is_int($value) || is_float($value)) {
$result = (string) $value;
$result = str_replace(",", ".", $result);
} elseif (is_string($value)) {
$result = $this->_encodeString($value);
} elseif (is_bool($value)) {
$result = $value ? 'true' : 'false';
}
return $result;
}
I'm not quite sure why you're HTML string would not be recognized as such, but I might try typecasting it prior to encoding.
array('html' => (string) $yourHtmlStr);
Solution 3
This usually happens if you use substr() or use $somestring[0] on a utf-8 string which has multibyte letters. Use mb_ prefixed functions to edit this sort of data, then you will not have problem with json_encode()

My Zend_Json is messing up in encoding an object here. I'm encoding an associative array which has two elements: Element one is another associative array while element 2 is an HTML string. He's goofing up such that the Html string part contains just NULL!!?!?!?!?
Heres the element UNencoded when I do a var_dump on it...sorry for the looong element... Its very erratic - I don't understand whats wrong here...

EDIT
After some investigation I found this error in my error logs:
PHP Warning: json_encode() [<a href='function.json-encode'>function.json-encode</a>]: Invalid UTF-8 sequence in argument in C:\wamp\www\fltdata\library\Zend\Json.phpI think it might have something to do with the problem I'm facing? How do I fix this?
EDIT
My version of Php is 5.2.9-2 - I doubt this is due to the issue which was in versions earlier than 5.2.7... help here guys please!!!
EDIT
Running the object through json_encode() returns the same result and I get the same error:
PHP Warning: json_encode() [<a href='function.json-encode'>function.json-encode</a>]: Invalid UTF-8 sequence in argument in...I'm stumped here :(
SOLUTION
WOO HOOO!!!! I figured it out: I just run the html string variable through a utf8_encode function and then run the JSON encode function on it:
$result['html'] = utf8_encode($result['html']);
And it works - Thanks everybody for all the help guys - I feel heavily confined by not being able to vote more than once for each of the posts here - you've all been a fanstastic help :D Thanks again!!!
