替换PHP字符串中的特殊字符的问题 [英] Issues replacing special characters in PHP string
问题描述
我试图用普通字符替换PHP字符串中的特殊字符（如替换ó和o，á和a）。我尝试使用PHP Normalizer :: normalize函数，如下面的代码：
I'm trying to replace the special characters in a PHP string with normal characters (as in replace ó with o and á with a). I tried using the PHP Normalizer::normalize function as in the following code:
if (!Normalizer::isNormalized($word, Normalizer::FORM_C))
{
echo "original: ".$word;
$word = Normalizer::normalize($word, Normalizer::FORM_C);
echo "\tnormalized: ".$word."<br />";
exit; // see if it worked without having to go through every file
}
:: normalize返回null，该代码的输出为：
However, Normalizer::normalize returned null and the output from that code was:
original：adiósnormalized：
由于这个方法似乎不工作，我去了一个函数，应该删除特殊字符。这是函数：
Since this method didn't seem to be working, I went and found a function that was supposed to remove special characters. Here is the function:
function normalize ($string) {
$table = array(
'Š'=>'S', 'š'=>'s', 'Đ'=>'Dj', 'đ'=>'dj', 'Ž'=>'Z', 'ž'=>'z', 'Č'=>'C', 'č'=>'c', 'Ć'=>'C', 'ć'=>'c',
'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E',
'Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O',
'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U', 'Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss',
'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c', 'è'=>'e', 'é'=>'e',
'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o',
'ô'=>'o', 'õ'=>'o', 'ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'ý'=>'y', 'þ'=>'b',
'ÿ'=>'y', 'Ŕ'=>'R', 'ŕ'=>'r',
);
return strtr($string, $table);
}
这段代码没有明显的效果，传入。
This code had no noticeable effect, however, and returned the same string that was passed in.
我在Windows 7中从* .txt文件获取字符串。我从来没有很好的编码，并希望任何帮助问题。
I'm obtaining my strings from *.txt files in Windows 7. I've never been very good at encodings, and would appreciate any help on this issue.
推荐答案
我将代码复制并粘贴到我的编辑器中，发生了一些有趣的事情。我不是得到 adios 我得到adjiós。请注意d后的中间的 j 。这是来自表格映射第一行中的'đ'=>'dj'，。显然，我的编辑改变了đ为常规 d ，然后它不会转换ó。我删除了这个键/值对，突然它为我工作。您确定所有的键在编辑器中是否正确（您的编辑器是否接受替代字符集？）这是我的测试文件（đ已删除：
I copied and pasted your code into my editor and something interesting happened. Instead of getting adios I was getting adjiós. Notice the j in the middle after the d. This was coming from the 'đ'=>'dj', in the first line of the table map. Apparently, my editor changed the đ to a regular d, and then it wouldn't convert the ó. I removed this key/value pair and suddenly it worked for me. Are you sure all of your keys are correct in your editor (Does you editor accept alternative character sets?) Here is my test file (with the đ removed:

<?php
function normalize ($string) {
$table = array(
'Š'=>'S', 'š'=>'s', 'Ð'=>'Dj', 'Ž'=>'Z', 'ž'=>'z', 'C'=>'C', 'c'=>'c', 'C'=>'C', 'c'=>'c',
'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E',
'Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O',
'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U', 'Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss',
'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c', 'è'=>'e', 'é'=>'e',
'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o',
'ô'=>'o', 'õ'=>'o', 'ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'ý'=>'y', 'þ'=>'b',
'ÿ'=>'y', 'R'=>'R', 'r'=>'r',
);
return strtr($string, $table);
}
$word = 'adiós';
$length = strlen($word);
echo 'original: '. $word;
echo '<br />';
echo 'normalized: '. normalize($word);
echo '<br />';
echo 'loop: ';
for($i = 0; $i < $length; $i++) {
echo normalize($word[$i]);
}
?>
</body>
</html>
当我用'd'=> 'dj'在数组映射中，然后我正确地得到 adjios
When I loop through each character with the 'd' => 'dj' in the array map then I correctly get adjios
