PHP 中具有奇怪字符集行为的函数参数
我有以下 PHP 代码：
<?php
ini_set( 'default_charset', 'UTF-8' );
mb_internal_encoding('UTF-8');
function labelValidate($label)
{
echo mb_detect_encoding($label.'x', 'UTF-8, ISO-8859-1');
echo '<br />';
echo mb_detect_encoding('Rio, coração do Brasil', 'UTF-8, ISO-8859-1');
}
labelValidate('Rio, coração do Brasil');
?>
我得到以下输出：
ISO-8859-1 UTF-8
有人知道为什么参数 $label 具有 ISO 字符集，但我在函数内创建的直接 echo 具有 UTF-8 编码？
这让我很头疼，因为我必须在 $label var 中放入 utf8_encode，否则我会在输出中得到有问题的字符。
感谢您的帮助！
i have the following PHP code:
<?php
ini_set( 'default_charset', 'UTF-8' );
mb_internal_encoding('UTF-8');
function labelValidate($label)
{
echo mb_detect_encoding($label.'x', 'UTF-8, ISO-8859-1');
echo '<br />';
echo mb_detect_encoding('Rio, coração do Brasil', 'UTF-8, ISO-8859-1');
}
labelValidate('Rio, coração do Brasil');
?>
I get this output:
ISO-8859-1
UTF-8
Anybody knows why the parameter $label has ISO charset, but the direct echo which i created inside the function has UTF-8 encode?
This is generating a headache to me, because i have to put a utf8_encode in $label var, otherwise i get problematic chars in the output.
Thanks for any help!

这是关于你的文本编辑器的。
尝试从代码中删除“Rio, coração do Brasil”字符串，然后再写入一次。
It's about your text editor.
Try to delete both 'Rio, coração do Brasil' strings from code and write it one more time.
在@Marc B和@Michael Madsen的帮助下，我下载了Notepad++（PHP IDE）并将文件转换为无BOM的UTF-8字符集，所以我的所有问题都得到了解决。 Dreamweaver 将一些文件保存为 ANSI，这导致 PHP 上出现混乱。
非常感谢大家！

Many thanks for all!
