“\ u00e1n”到“á”在PHP [英] "\u00e1n" to "á" in PHP

问题描述

我收到一个带有字符串的外部文件，我不能控制该文件，但我收到特殊字符作为这个（我认为它是unicode？）序列\\\án。

谢谢！

p> EDIT：

我正在呼叫一个网址，其中列出了人名：

Tom \\\ánsson\\\

Eriksen \\\

Gilverto \\\

我正在读姓名

解决方案

EDIT

现在，我已经找出了正确的，工作的答案基于我发现的文章。这是它：

  function unicode2utf8（$ str）{
 $ a = json_decode（str_replace（\\\
 ，< br>，['。$ str。']'））; 
 return str_replace（< br>，\\\
，$ a [0]）; 
} 
  

PHP：

  echo unicode2utf8（Tom \\\ánsson\\\
 Eriksen \ Gilverto \\\
）; 
  

输出：

 code>Tománsson
 Eriksen 
 Gilverto

我在这里找到一篇关于同样问题的文章（ http://www.welefen.com/php-unicode-to-utf8.html ）

解决方案是以下函数

  function unicode2utf8（$ str）{
 if（！$ str）return $ str; 
 $ decode = json_decode（$ str）; 
 if（$ decode）return $ decode; 
 $ str ='['。$ str。']'; 
 $ decode = json_decode（$ str）; 
 if（count（$ decode）== 1）{
 return $ decode [0]; 
} 
 return $ str; 
} 
  

我试过了

  echo unicode2utf8（\\\á）; 
  

输出：

 code>á
  

I am receiving an external file with strings, I have no control over that file but I receive special characters as this (i think it's unicode?) sequence \u00e1n.

Is there anyway to convert this kind of char sequences to their "readable" counterparts?

Thanks!

EDIT:

I am calling a url that gives me a list with names of persons:

Tom\u00e1nsson\n Eriksen\n Gilverto\n

I am reading the names and showing them in my site.

解决方案

EDIT

Now, I've figured out the correct, working answer based on the article I found. Here is it:

function unicode2utf8($str) {
    $a=json_decode(str_replace("\n","<br>",'["'.$str.'"]'));
    return str_replace("<br>","\n",$a[0]);
}

PHP:

echo unicode2utf8("Tom\u00e1nsson\n Eriksen\n Gilverto\n");

Output:

Tománsson
 Eriksen
 Gilverto

I've found an article about the same problem here ( http://www.welefen.com/php-unicode-to-utf8.html )

The solution is the following function

function unicode2utf8($str){
    if(!$str) return $str;
    $decode = json_decode($str);
    if($decode) return $decode;
    $str = '["' . $str . '"]';
    $decode = json_decode($str);
    if(count($decode) == 1){
            return $decode[0];
    }
    return $str;
}

I've tried it with

echo unicode2utf8("\u00e1");

Output:

á
