PHP 和 Â 的字符编码问题特点

发布于 2024-09-16 10:50:50 字数 564 浏览 3 评论 0原文

我遇到一个问题，PHP (5.2) 无法在字符串中找到字符“Â”，尽管它显然在那里。

我意识到根本问题与字符编码有关，但不幸的是我无法控制源内容。我收到的格式为 UTF-8，这些字符已在字符串中。

我只想将其从字符串中删除。 strpos()、str_replace()、preg_replace()、trim()等无法正确识别。

我的字符串是这样的：

"Â  Â  Â  A lot of couples throughout the World "

如果我这样做：

$string = str_replace('Â','',$string);

我得到这个：

"Â� Â� Â� A lot of couples throughout the World"

我什至在 str_replace 之前尝试过 utf8_encode() 和 utf8_decode() ，但没有运气。

解决办法是什么？我已经把我能找到的所有东西都扔进去了......

I'm having a problem where PHP (5.2) cannot find the character 'Â' in a string, though it is clearly there.

I realize the underlying problem has to do with character encoding, but unfortunately I have no control over the source content. I receive it as UTF-8, with those characters already in the string.

I would simply like to remove it from the string. strpos(), str_replace(), preg_replace(), trim(), etc. Cannot correctly identify it.

My string is this:

"Â  Â  Â  A lot of couples throughout the World "

If I do this:

$string = str_replace('Â','',$string);

I get this:

"Â� Â� Â� A lot of couples throughout the World"

I even tried utf8_encode() and utf8_decode() before the str_replace, with no luck.

What's the solution? I've been throwing everything I can find at it...

$string = str_replace('Â','',$string);

这个“”是如何编码的？如果您的脚本文件保存为 iso-8859-1，则字符串 'Â' 会编码为单字节序列 xC2，而 (/one) utf-8 表示形式为 xC3 x82。 php 的 str_replace() 在字节级别上工作，即它只“识别”单字节字符。

请参阅 http://docs.php.net/intro.mbstring

$string = str_replace('Â','',$string);

How is this 'Â' encoded? If your script file is saved as iso-8859-1 the string 'Â' is encoded as the one byte sequence xC2 while the (/one) utf-8 representation is xC3 x82. php's str_replace() works on the byte level, i.e. it only "knows" single-byte characters.

我用这个：

function replaceSpecial($str){
$chunked = str_split($str,1);
$str = ""; 
foreach($chunked as $chunk){
    $num = ord($chunk);
    // Remove non-ascii & non html characters
    if ($num >= 32 && $num <= 123){
            $str.=$chunk;
    }
}   
return $str;
}

I use this:

function replaceSpecial($str){
$chunked = str_split($str,1);
$str = ""; 
foreach($chunked as $chunk){
    $num = ord($chunk);
    // Remove non-ascii & non html characters
    if ($num >= 32 && $num <= 123){
            $str.=$chunk;
    }
}   
return $str;
}
