htaccess重写规则重定向到文件与否

Question

I have been trying to write a set of htaccess rules that will do the following:

• With the url: mydomain.com/blog/something

  • If a file called blog.php exists in
    the web directory(the directory with index.php in) then redirect to
    blog.php?url=something

  • If blog.php does not exist, redirect to index.php?url=blog/something

  • EDIT: mydomain.com/blog/something is an example, it could be any url string and the htaccess should search the web directory for a file corresponding to the first part of the url string, which in this case is "blog"

In both cases I can then use $_GET['url'] to get parameters from the url to intiate whatever actions in my php script.

I currently have:

Options +FollowSymLinks +ExecCGI

<IfModule mod_rewrite.c>
RewriteEngine On

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

RewriteRule ^([^/]*)/(.*)$ $1.php?url=$2 [L]
RewriteRule ^(.*)$ index.php?url=$1 [L]

</IfModule>

But unfortunately this is not working, I'm not sure why, I'm proficient enough with php but my htaccess skills are pretty limited. I don't know if the [L] option is the one I should be using or if I should be using more options. Currently whatever the url string is, $_GET['url'] returns "index.php".

If any more information is required just ask.

I hope someone can help Regards Luke

I hope that the following directives will work for you.

Options +FollowSymLinks +ExecCGI

<IfModule mod_rewrite.c>
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]*)/?.*$ - [E=FILE:%{DOCUMENT_ROOT}/$1.php]

RewriteCond %{ENV:FILE} !^$
RewriteCond %{ENV:FILE} -f
RewriteRule ^([^/]*)/?(.*)$ $1.php?url=$2 [QSA,L]

RewriteCond %{ENV:FILE} !^$
RewriteCond %{ENV:FILE} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>
