.htaccess和mod_rewrite重写为最近的文件

Question

given a directory structure of:

/test/
/test/a
/test/a/b
/test/a/b/c

Each directory, in the above example, has an index file, index.php, in it. I have a single .htaccess in /test/ ... I would like to avoid having a .htaccess in each directory.

I need to write a rewrite rule that will display the closest index.php to a URL that is entered into a system.

For example:

url /test/a/b/1234 should get rewritten to /test/a/b/index.php
url /test/a/b/c/1234 should get rewritten to /test/a/b/cindex.php
url /test/1234 should get rewritten to /test/index.php

I've tried several different .htaccess, but everything gets rewritten to /test/index.php

<IfModule mod_rewrite.c>
      RewriteEngine On

      RewriteCond %{REQUEST_FILENAME} !-f
      RewriteCond %{REQUEST_FILENAME} !-d

      RewriteRule . index.php [L]
</IfModule>

I've also tried RewriteRule . ./index.php [L] RewriteRule . ./index.php [L]

If i set a RewriteBase to be one of the sub directories it does rewrite to the index.php in that base. but then everything gets written to that base.

Thanks in advance.

Update:

The url length is unknown. Example:

url /test/a/b/1234/abcd/this/that/another should get rewritten to /test/a/b/index.php

Essentially, I need to know the directory from which .htaccess was matched in to use as the rewritebase for the rewriterule.

Answer 1

You can use this rule:

RewriteEngine On

## recursively search parent dir
# if index.php is not found then
# forward to the parent directory of current URI
RewriteCond %{DOCUMENT_ROOT}/$1$2/index.php !-f
RewriteRule ^(.*?)([^/]+)/[^/]+/?$ /$1$2/ [L]

# if current index.php is found in parent dir then load it
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}/$1index.php -f
RewriteRule ^(.*?)[^/]+/?$ /$1index.php [L]

Answer 2

This should work:

RewriteEngine On
RewriteRule ^test/([A-Za-z]+)/([A-Za-z]+)/([A-Za-z]+)/([0-9]+)(.*)$ /test/$1/$2/$3/index.php [L]
RewriteRule ^test/([A-Za-z]+)/([A-Za-z]+)/([0-9]+)(.*)$ /test/$1/$2/index.php [L]
RewriteRule ^test/([0-9]+)(.*)$ /test/index.php [L]
