Php 使用.htaccess重新写入url

我已编写.htaccess来重写以下URL：

confirmreg.php

到

及

到

.htaccess规则为

RewriteRule confirm-registration\.html$ confirmreg.php [QSA,L]
RewriteRule code/(.*)/confirm-registration\.html$ confirmreg.php?code=$1 [QSA,L]

Echo Get不返回代码的值

echo "Code: ". $_GET['code'];

改进代码：

RewriteRule ^confirm-registration\.html$ confirmreg.php [QSA,L]
RewriteRule ^code/([0-9a-z]+)/confirm-registration\.html$ confirmreg.php?code=$1 [QSA,L]

给规则一个开始^

RewriteRule ^

（可选）在要删除的字符中更加具体

code/([0-9a-z]+)/

---

print\r（$\u-GET）是什么显示？它在url中显示代码
RewriteRule ^confirm-registration\.html$ confirmreg.php [QSA,L]
RewriteRule ^code/([0-9a-z]+)/confirm-registration\.html$ confirmreg.php?code=$1 [QSA,L]

RewriteRule ^

code/([0-9a-z]+)/
