PHP中的奇怪字符集行为的函数参数

问题描述

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，coraçãodo Brasil'，'UTF-8，ISO-8859-1'）; 
} 
 
 labelValidate（'Rio，coraçãodo Brasil'）; 
 
？> 
  

我得到这个输出：

ISO -8859-1
UTF-8

任何人都知道为什么参数$ label有ISO字符集，但是我在函数中创建的直接回声有UTF- 8 encode？

这会让我头痛，因为我必须在$ label var中添加一个utf8_encode，否则会在输出中产生有问题的字符。

感谢您的帮助！

解决方案

@Michael Madsen，我下载了Notepad ++（PHP IDE）并转换了没有BOM的文件UTF-8字符集，所以我的所有问题都已解决。 Dreamweaver正在将一些文件保存为ANSI，这是生成对PHP的混乱。

非常感谢所有！

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-8859-1UTF-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!

解决方案

With the help of @Marc B and @Michael Madsen, i downloaded Notepad++ (PHP IDE) and converted the file UTF-8 charset without BOM, so all my problems have been resolved. The Dreamweaver was saving some files as ANSI, this was generationg the confusion on PHP.

Many thanks for all!
