函数在PHP中删除重音符号和其他字符的问题 [英] Problem with function removing accents and other characters in PHP
问题描述
我发现了一个简单的函数，可以从字符串中删除一些不需要的字符.
I found a simple function to remove some undesired characters from a string.
function strClean($input){
$input = strtolower($input);
$b = array("á","é","í","ó","ú", "ñ", " "); //etc...
$c = array("a","e","i","o","u","n", "-"); //etc...
$input = str_replace($b, $c, $input);
return $input;
}
当我将其用于重音符号或其他字符时，例如áéñí"一词，它会打印出那些问号或奇怪的字符，例如: 输出http://img217.imageshack.us/img217/6794/59472278.jpg
When I use it on accents or other characters, like this word 'á é ñ í' it prints out those question marks or weird characters, like: output http://img217.imageshack.us/img217/6794/59472278.jpg
注意:我正在UTF-8中使用strclean.php(包含此函数)和index.php. index.php如下所示:
Note: I'm using strclean.php (which contains this function) and index.php, both in UTF-8. index.php looks as follows:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title></title>
</head>
<body>
<?php
include('strclean.php');
echo 'óóóáà';
echo strClean('óóóáà');
?>
</body>
</html>
我在做什么错了?
推荐答案
我已经测试了您的代码，并且strtolower函数出错...
I have tested your code, and error is in strtolower function...
用mb_strtolower代替它，例如波纹管
Replace it with mb_strtolower, like bellow
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
</head>
<body>
<?php
function strClean($input) {
$input = mb_strtolower($input, 'UTF-8');
$b = array("á","é","í","ó","ú", "n", " ");
$c = array("a","e","i","o","u","n", "-");
return str_replace($b, $c, $input);
}
$string = 'á é í ó ú n abcdef ghij';
echo $string ."<br />". strClean($string);
?>
</body>
</html>
