php - 强制小写 .htaccess

Question

我试过

RewriteEngine On
RewriteMap  lc int:tolower
RewriteCond %{REQUEST_URI} [A-Z]
RewriteRule (.*) ${lc:$1} [R=301,L]

但是，我收到了 500 内部错误。不确定出了什么问题。

错误:

/home/public_html/.htaccess: RewriteMap not allowed here
[Mon Jul 18 10:33:06 2011] [alert] [client *.*.*.*] /home/public_html/.htaccess: RewriteMap not allowed here

Answer 1

如果你使用 PHP，你可以把它放在你的 index.php 的开头

$url = $_SERVER['REQUEST_URI'];
$pattern = '/([A-Z]+)/';

if(preg_match($pattern, $url)) {
    $new_url = strtolower($url);

    Header( 'HTTP/1.1 301 Moved Permanently' );
    Header( 'Location: ' . $new_url );
    exit;
}
