Zend_JSON:Encode messing up - why?

Question

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

Answer 1

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()

Answer 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);

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()?
