双 .htaccess：$_GET 变量为空。我能做些什么？
我目前正在开发一个项目，其中我的 Apache 文档根目录与我的 index.php 所在的公共目录不同。奇怪的是，由于这种设置，我的 $_GET 超级全局似乎被清空了。
目录结构：
- /Documentroot
- /Documentroot/.htaccess
- /public/.htaccess
- /public/index.php
处理第一个 .htaccess 后出现问题。
#First .htaccess in Apache documentroot:
RewriteEngine On
RewriteRule (.+) public/$1 [NC,L]
# Second .htaccess in /documentroot/public:
SetEnv APPLICATION_ENV testing
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]
一些观察：
- 当删除主.htaccess并在documentoot中放置额外的index.php时，我的$_GET变量显示良好
- 当在/public/index.php文件中转储$_GET时，它是空的
- 当调用像/?foo=bar这样的index.php时，$_GET为空
- 当像/index.php?foo=bar这样调用index.php时$_GET被填充
什么可能导致$_GET变量被清空？< /strong> 任何帮助表示赞赏。
编辑：事情变得更加奇怪：
当我保持两个 .htaccess 文件完好无损并放置一个 index.php （或任何与此相关的 index.* ）文件时（无论 documentroot 中的内容是什么，都会解析 /public 目录中的 index.php 文件并正确填充 $_GET 变量。
I am currently working on a project in which my Apache documentroot differs from the public directory in which my index.php resides. Strangely, due to this setup, my $_GET superglobal seems to be emptied.
Directory structure:
- /Documentroot
- /Documentroot/.htaccess
- /public/.htaccess
- /public/index.php
Things go wrong after the first .htaccess is processed.
#First .htaccess in Apache documentroot:
RewriteEngine On
RewriteRule (.+) public/$1 [NC,L]
# Second .htaccess in /documentroot/public:
SetEnv APPLICATION_ENV testing
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]
Some observations:
- When removing the primary .htaccess and placing an additional index.php in the documentoot, my $_GET variables show fine
- When dumping $_GET in the /public/index.php file, it is empty
- When calling index.php like /?foo=bar, $_GET is empty
- When calling index.php like /index.php?foo=bar $_GET is populated
What could be causing the $_GET variable to be emptied? Any help is appreciated.
EDIT: things just got a whole lot stranger:
When I leave both .htaccess files intact and place an index.php (or any index.* for that matter) file (no matter what content) in the documentroot, the index.php file in the /public directory is parsed and the $_GET variable is properly populated.

我在这里猜测，但是当请求
/?foo=bar时，正则表达式 (.+) 可能会尝试匹配空字符串，从而导致测试失败。尝试将其更改为 (.*)。编辑：实际上，再想一想，当请求
/?foo=bar时，如果它匹配“/”，那么它会重写为public//，它将被重写为index.php按照您的最后一条规则。也许尝试^/?(.*)$作为您的第一个模式。I'm guessing here, but when requesting
/?foo=bar, The regex (.+) may be trying to match against the empty string, which fails the test. Try changing it to (.*).Edit: Actually, on second thought, when requesting
/?foo=bar, if it matches "/", then it rewrites topublic//, which will get rewritten toindex.phpby your last rule. Maybe try^/?(.*)$as your first pattern.发生的情况是这样的：
/?foo=bardocumentroot/.htaccess中的RewriteRule重定向到public/?foo=bar< /code>public/.htaccess中，RewriteCond检查它是文件、符号链接还是目录。字符串/?foo=bar不是这些，因此第一个RewriteRule被跳过。RewriteRule ^.*$ index.php [NC, L]运行。这会将所有内容定向到index.php——这是一个没有任何 $_GET 变量的 URL。这就是他们消失的原因。您需要在最后一个
RewriteRule中传递这些 GET 变量。Here's what's happening:
/?foo=barRewriteRuleindocumentroot/.htaccessredirects topublic/?foo=barpublic/.htaccess, theRewriteConds check whether it is a file, a symlink, or a directory. The string/?foo=baris none of those, so the firstRewriteRuleis skipped.RewriteRule ^.*$ index.php [NC, L]is run. This directs all toindex.php-- which is a URL without any $_GET variables. That's why they're disappearing.You need to pass those GET variables in that last
RewriteRule.
