问题描述
有没有办法告诉PHP使用UTF-8作为默认的函数 htmlspecialchars ？
Is there a way to tell PHP to use UTF-8 as default for functions like htmlspecialchars ?
我已经设置了：
ini_set('mbstring.internal_encoding','UTF-8');
ini_set('mbstring.func_overload',7);
如果没有，请发布一个所有函数的列表， $ c> charset ？
If not, please can you post a list of all functions where I need to specify the charset?
（我需要这个，因为我重新分解我的框架以使用UTF- p>
(I need this because I am re-factorizing all my framework to get working with UTF-8)
推荐答案
只需使用 htmlspecialchars（）而不是 htmlentities （）。因为它不接触非ASCII字符，无论是否使用'utf8'字符集或默认'latin1'（*），结果是一样的。作为奖励，你的输出更小。 （
Just use htmlspecialchars() instead of htmlentities(). Because it doesn't touch the non-ASCII characters, it doesn't matter whether you use 'utf8' charset or the default 'latin1'(*), the results are the same. As a bonus your output is smaller. (Though it does mean you have to ensure you're actually serving your page with the correct encoding.)
（*：有几个东亚多字节字符集可以不同的ASCII码点的使用，所以如果你使用那些你仍然需要传递 $ charset 参数到 htmlspecialchars（）。但是对于UTF-8肯定没有这样的问题。）
(*: there are a few East Asian multibyte charsets which can differ in their use of ASCII code points, so if you're using those you would still need to pass a $charset argument to htmlspecialchars(). But certainly no such problem for UTF-8.)
