PHP中的怪异破折号 [英] Weird dash character in PHP

问题描述

我的文字中有一个奇怪的破折号，在str_replace中未检测到.

I have a weird dash in my text, which isn't being detected in a str_replace.

这里是一个例子:

Sun: 10:00 – 3:00pm

我不知道破折号是否会显示在这里..但是当它插入到我的表中时，它就像一个带有字符0096

I don't know if the dash will show up on here.. but when it is inserted into my table, it is like a square box with the characters 0096

它看起来很像–-在查看源代码时，没有特殊字符，只有破折号.

It looks a lot like an – - when viewing the source, there is no special characters, just the dash.

str_replace('–', '', $var);

上面的替换似乎没有抓住，其他人以前有过这个麻烦吗?

The above replace doesn't seem to catch it, has anyone else had this trouble before?

推荐答案

这是 html_entity_decode :

$endash = html_entity_decode('–', ENT_COMPAT, 'UTF-8');
echo str_replace($endash, '(en dash)', 'Sun: 10:00 – 3:00pm');

请注意，仅当您的网站编码为UTF-8 并且您的编辑器编码(或str_replace的第三个参数的编码)也是如此时，此方法才有效.如果您使用其他编码(并且网站和编辑器都应使用相同的编码)，请将html_entity_decode的第三个参数替换为其名称.

Note that this only works if your website encoding is UTF-8 and your editor encoding(or the encoding of the third argument to str_replace) is as well. If you use another encoding (and you should use the same both for website and editor), replace the third parameter of html_entity_decode with its name.
