PHP解析问题 - & nbsp;和Â [英] PHP Parsing Problem -   and Â

问题描述

当我尝试解析一些具有& nbsp; 的html，然后通过 echo & nbsp; 变成这个字符：。此外， html_entity_decode（）和 str_replace（）不会更改。

When I try to parse some html that has   sprinkled through it and then echo it, the   "turns into" this character: Â. Also, html_entity_decode() and str_replace() doesn't change it.

为什么会发生这种情况？如何删除Â的？

Why is this happening? How can I remove the Â's?

推荐答案

不间断空格存在于 UTF-8 中两个字节： 0xC2 和 0xA0 。

The non-breaking space exist in UTF-8 of two bytes: 0xC2 and 0xA0.

当这些字节在 ISO-8859 -1 （单字节编码）而不是UTF-8（多字节编码），那么这些字节分别变成字符 打破空格 。

When those bytes are represented in ISO-8859-1 (a single-byte encoding) instead of UTF-8 (a multi-byte encoding) then those bytes becomes respectively the characters Â and another non-breaking space .

显然，您使用UTF-8解析HTML，并使用ISO-8859 -1。要解决此问题，您需要 使用ISO-8859-1 解析HTML或使用UTF-8回显结果。我建议使用UTF-8一路。请浏览 PHP UTF-8欺骗表单，使其一切正常。

Apparently you're parsing the HTML using UTF-8 and echoing the results using ISO-8859-1. To fix this problem, you need to either parse HTML using ISO-8859-1 or echo the results using UTF-8. I'd recommend to use UTF-8 all the way. Go through the PHP UTF-8 cheatsheet to align it all out.
