PHP转换外国字符与口音 [英] PHP convert foreign characters with accents

问题描述

您好我试图将一些文本与数据库中的文本进行比较。在数据库中，任何具有重音的文本都会像html（即& eacute;）中编码，当我将数据库文本与我的字符串它不匹配，因为我的字符串只是显示é..当我使用php函数htmlentities编码字符串首先é变成é奇怪的？使用htmlspecialchars不会编码é所有..

Hi I'm trying to compare some text to the text in a database.. in the database any text with an accent is encoded like in html (ie. é) when I compare the database text to my string it doesn't match because my string just shows é .. when I use the php function htmlentities to encode the string first the é turns into é weird? using htmlspecialchars doesn't encode the é at all..

你会建议我比较é和é以及所有其他重音字符？

how would you suggest I compare é to é as well as all the other accented characters?

推荐答案

您需要发送正确的字符集到htmlentities。看起来您使用的是UTF-8，但默认值为ISO-8859-1。像这样更改：

You need to send in the correct charset to htmlentities. It looks like you're using UTF-8, but the default is ISO-8859-1. Change it like this:

$encoded = htmlentities($text, ENT_COMPAT, 'UTF-8');

另一个解决方案是在编码之前将文本转换为ISO-8859-1，但这可能会破坏信息（ISO-8859-1不包含与UTF-8几乎相同的字符）。如果你想尝试，请这样做：

Another solution is to convert the text to ISO-8859-1 before encoding, but that may destroy information (ISO-8859-1 does not contain nearly as many characters as UTF-8). If you want to try that instead, do like this:

$encoded = htmlentities(utf8_decode($text));
