Question

我从数据库获取utf8编码的数据。但不知何故，一些旧数据包含latin1字符。

所以这个

$encod = mb_detect_encoding($string, 'UTF-8', true);

始终是正确的。

总是使用utf8_decode（）来检查像'äöüß'这样的拉丁文字符是否安全？

$string = utf8_decode($string);
$search = Array(" ", "ä", "ö", "ü", "ß", "."); //,"/Ä/","/Ö/","/Ü/");
$replace = Array("-", "ae", "oe", "ue", "ss", "-"); //,"Ae","Oe","Ue");
$string = str_replace($search, $replace, strtolower($string));

此致

Answer 1

似乎没有utf8_encoding：

<?php
   $string = "äöüß";
   $search = Array(" ", "ä", "ö", "ü", "ß", "."); //,"/Ä/","/Ö/","/Ü/");
   $replace = Array("-", "ae", "oe", "ue", "ss", "-"); //,"Ae","Oe","Ue");
   $string = str_replace($search, $replace, strtolower($string));
   echo $string;
?>

使用htmlspecialchars（）;工作更安全。更多信息：
