我的Zend_Json在编写一个对象时搞砸了。我正在编码一个有两个元素的关联数组： 元素1是另一个关联数组，而元素2是HTML字符串。他搞砸了，以至于Html字符串部分只包含NULL !!？！？！？！？
当我对它执行var_dump时，继承了未编码的元素...对于looong元素抱歉... 它非常不稳定 - 我不明白这里有什么不对......

最后注意 - HTML的巨大喧嚣 - GONE被null取代......这里发生了什么：（
修改
经过一些调查后，我在错误日志中发现了这个错误：
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.php
我认为这可能与我面临的问题有关？我该如何解决这个问题？
修改
我的Php版本是5.2.9-2 - 我怀疑这是由于5.2.7之前版本的问题...请帮助这些人!!!
修改
通过json_encode（）运行对象会返回相同的结果，我得到同样的错误：
PHP Warning: json_encode() [<a href='function.json-encode'>function.json-encode</a>]: Invalid UTF-8 sequence in argument in...
我在这里难过:(
解
WOO HOOO !!!!我想通了：我只是通过utf8_encode函数运行html字符串变量，然后在其上运行JSON编码函数：
$ result ['html'] = utf8_encode（$ result ['html']）;
它的确有效 - 感谢所有人的帮助 - 我对这里的每个帖子都不能多次投票感到非常紧张 - 你们都得到了一个很好的帮助：D再次感谢!!!
答案 0 :(得分：12)
您可以通过将PHP版本更新为5.2.7之后的版本来解决此问题。
在该版本之前，PHP的serious UTF-8 bug函数中有json_encode。有关详细信息，请参阅changelog。
由于您注意到您使用的是PHP版本5.2.9.2，因此您的版本应该是好的:)您是否尝试通过PHP的json_encode（）手动路由html的特定内容？
或者可能通过utf8_encode()或utf8_decode()？
答案 1 :(得分：2)
我只看到一个可能从Encoder.php返回NULL的区域。我将通过在 Zend / Json / Encoder.php
中的此函数内部执行一些var_dump来开始调试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;
}
我不太确定为什么你的HTML字符串不会被识别出来，但我可能会在编码之前尝试对其进行类型转换。
array('html' => (string) $yourHtmlStr);
答案 2 :(得分：1)
如果您在具有多字节字母的utf-8字符串上使用substr()或使用$somestring[0]，通常会发生这种情况。使用mb_前缀函数编辑此类数据，然后您就不会遇到json_encode()
