""出现而不是“& nbsp;”字符 [英] "Â " character showing up instead of " "

问题描述

我发现此线程很好地描述了我的问题，而此答案恰好描述了我的问题。

I found this thread which describes my issue pretty well and this answer describes my issue exactly.

不间断空格字符是字节0xA0，是ISO-8859-1；当编码为UTF-8时，它将为0xC2,0xA0，如果（错误地）将其视为ISO-8859-1，则显示为 。其中包括结尾的nbsp ...

The non-breaking space character is byte 0xA0 is ISO-8859-1; when encoded to UTF-8 it'd be 0xC2,0xA0, which, if you (incorrectly) view it as ISO-8859-1 comes out as "Â ". That includes a trailing nbsp...

但是，我设法将问题归结为用于包装图片标签的函数

However, I have managed to track my issue down to a function I use to wrap image tags in divs.

function img_format($str)
{
    $doc = new DOMDocument();
    @$doc->loadHTML($str);     // <-- Bonus points for the explaination of the @

    // $tags object
    $tags = $doc->getElementsByTagName('img');

    foreach ($tags as $tag) {

        $div = $doc->createElement('div');
        $div->setAttribute('class','inner-copy');
        $tag->parentNode->insertBefore($div, $tag);
        $div->appendChild($tag);

        $tag->setAttribute('class', 'inner-img');
    }

    $str = $doc->saveHTML();

    return $str;
}

很简单，如何在此函数中解决此问题？

Quite simply, how can I fix this issue within this function?

我理解使用；

<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />

可以解决此问题，但显然我在函数本身中忽略了某些事情。

will fix this issue, but there is obviously something I'm overlooking within the function itself.

我已经尝试过；

$dom->validateOnParse = true;

无济于事。 （我还是不太清楚该怎么做）

To no avail. (I don't quite know what that does anyway)

推荐答案

找到了！

@$doc->loadHTML(mb_convert_encoding($str, 'HTML-ENTITIES', 'UTF-8'));

此答案解释了该问题并给出了上面的解决方法；

This answer explains the issue and gives the work around above;

DOMDocument :: loadHTML将把您的字符串视为ISO-除非另有说明，否则为8859-1。这导致UTF-8字符串被错误地解释。

DOMDocument::loadHTML will treat your string as being in ISO-8859-1 unless you tell it otherwise. This results in UTF-8 strings being interpreted incorrectly.
