推荐答案

根据手册，当不使用ISO-8859-1字符串提供此功能时，您需要提供一个字符集:

According to the manual, when not feeding this function with ISO-8859-1 strings, you need to provide a charset:

echo htmlentities($row['name'], ENT_QUOTES, 'UTF-8');

2015年3月更新:请注意，自此答案以来，此函数使用的默认字符集已针对不同版本进行了更改:

Update March 2015: Note that since this answer, the default character set this function uses has been changed for different versions:

• PHP< 5.4:ISO-8859-1
• PHP 5.4& 5.5:UTF-8
• PHP> = 5.6:default_charset设置(非常受欢迎，并且应该放在第一位).

• PHP < 5.4: ISO-8859-1
• PHP 5.4 & 5.5: UTF-8
• PHP >= 5.6: the default_charset setting (which is very welcome, and how it should have been in the first place).
