Do I need to set ini_set( 'default_charset', 'UTF-8' );?
提问by dynamic
My framework for each pages does the follow:
我对每个页面的框架如下：
ini_set('mbstring.internal_encoding','UTF-8');
ini_set('mbstring.func_overload',7);
header('Content-Type: text/html; charset=UTF-8');
Do I need to do a ini_set( 'default_charset', 'UTF-8' );too?
我也需要做ini_set( 'default_charset', 'UTF-8' );吗？

No, you don't have to.
不，你不必。
header('Content-Type: text/html; charset=UTF-8');
sets this for every page already
已经为每个页面设置了这个

When it comes to the http-header, you're OK as the other answers explain.
当涉及到 http 标头时，您可以像其他答案所解释的那样。
But: There are some functions that are default charset aware
但是：有一些函数可以识别默认字符集
From the description of FILTER_SANITIZE_FULL_SPECIAL_CHARS:
来自FILTER_SANITIZE_FULL_SPECIAL_CHARS的描述：
Like htmlspecialchars, this filter is aware of the default_charset and if a sequence of bytes is detected that makes up an invalid character in the current character set then the entire string is rejected resulting in a 0-length string.
与 htmlspecialchars 一样，此过滤器知道 default_charset，如果检测到构成当前字符集中无效字符的字节序列，则拒绝整个字符串，从而导致长度为 0 的字符串。

Please see https://bugs.php.net/bug.php?id=29983looks to me like some distros still have the problem
请参阅https://bugs.php.net/bug.php?id=29983在我看来，某些发行版仍然存在问题
test case
测试用例
echo "ini_get('default_charset') ". ini_get('default_charset')."<br>";
if (!ini_set('default_charset', 'utf-8')) {
echo "could not set default_charset to utf-8<br>";
}

default_charset ini setting should work for you. PHP always outputs a character encoding by default in the Content-type: header using this setting
default_charset ini 设置应该适合您。默认情况下，PHP 总是在 Content-type: 标头中使用此设置输出字符编码
