乌克兰语和法语重音lettres编码 [英] ucwords and french accented lettres encoding

问题描述

我们有一个加拿大地址的数据库全部在CAPS，客户要求我们转换为小写预期第一个字母和一个' - '之后的字母

所以我做了这个功能，但我有法国重音字母的问题。

当有文件和字符集作为ISO-88591它工作正常，但是当我尝试使它成为UTF-8它不再工作。

输入示例：'damien-claudeélanger'
输出：Damien-Claudeélanger

utf-8中的é将成为

  function cap_letter（$ string）{
 $ lower = str_split（àáâçèéêë）; 
 $ caps = str_split（ÀÁÇÈÉÊË）; 
 $ letters = str_split（strtolower（$ string））; 
 
 foreach（$ letters as $ code => $ letter）{
 if（$ letter ===' - '|| $ letter ===''）{
 $ position = array_search（$ letters [$ code + 1]，$ lower）; 
 if（$ position！== false）{
 // test 
 echo $ letters [$ code + 1]。 '=='。 $ caps [$ position]; 
 $ letters [$ code + 1] = $ caps [$ position]; 
} 
 else {
 $ letters [$ code + 1] = mb_strtoupper（$ letters [$ code + 1]）; 
} 
} 
} 
 // return ucwords（implode（$ letters））; 
 return implode（$ letters）; 
} 
  

我想到的其他解决方案是做：ucwords（strtolower（$ str）），因为所有的地址都已经在上限，所以É将保持É即使在使用strtolower之后。

但是，我会遇到É内部的问题：XXXÉXXÉ

解决方案

为多字节字符尝试 mb _ * 字符串函数。 / p>

  echo mb_convert_case（mb_strtolower（$ str），MB_CASE_TITLE，UTF-8）; 
  

We have a database of Canadian addresses all in CAPS , the client requested that we transform to lower case expect the first letter and the letter after a '-'

So i made this function , but I'm having problem with french accented letters .

When having the file and charset as ISO-88591 It works fine , but when i try to make it UTF-8 it doesn't work anymore .

Example of input : 'damien-claude élanger' output : Damien-Claude élanger

the é in utf-8 will become �

 function cap_letter($string) {
            $lower     = str_split("àáâçèéêë");
            $caps      = str_split("ÀÁÂÇÈÉÊË");
            $letters   = str_split(strtolower($string));

            foreach($letters as $code => $letter) {
                if($letter === '-' || $letter === ' ') {
                    $position = array_search($letters[$code+1],$lower);
                    if($position !== false) {
                        // test
                        echo $letters[$code+1] . ' == ' . $caps[$position] ; 
                        $letters[$code+1] = $caps[$position];
                    }
                    else {
                        $letters[$code+1] = mb_strtoupper($letters[$code+1]);
                    } 
                }
            }
            //return ucwords(implode($letters)) ;
            return implode($letters) ;
        }

The Other solution i have in mind is to do : ucwords(strtolower($str)) since all the addresses are already in caps so the É will stay É even after applying strtolower .

But then I'll have the problem of having É inside ex : XXXÉXXÉ

解决方案

Try mb_* string functions for multibyte characters.

echo mb_convert_case(mb_strtolower($str), MB_CASE_TITLE, "UTF-8");
