htaccess: Remove PHP extension only for specific files or folder

Question

I am currently using the following in /public_html/.htaccess to strip .php extensions and force trailing slashes.

# Remove .php extension RewriteCond %{THE_REQUEST} ^GET\ /[^?\s]+\.php RewriteRule (.*)\.php$ /$1/ [L,R=301] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} ^/(.+)/$ RewriteCond %{DOCUMENT_ROOT}/%1.php -f RewriteRule ^(.*)/$ $1.php [L] # Force trailing slash RewriteCond %{REQUEST_FILENAME}.php -f RewriteRule .*[^/]$ $0/ [L,R=301] 

This works perfectly, however, there are a number of PHP files in subfolders of /public_html that we don't want to be rewritten.

How can I modify the rewrite + trailing slash to apply only to PHP files in the /public_html folder, or, to specify a list of PHP files that the rule applies to?

UPDATE: In my case, I believe the optimal solution will be to strip the PHP extension (and add trailing slash) only to files explicitly specified, rather than creating folder-based conditions.

UPDATE 2: Working solution:

#Remove PHP extension from named files RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(file1|file2)/?$ /$1.php [L,NC] 

Answer 1

You could simply make an exception at the start of your .htaccess file... if the request matches one of these subfolders (and is an existing PHP file?) then stop the rewriting process. For example:

RewriteRule ^(subfolder1|subfolder2)$ - [L] 

If you simply want to skip all requests then you can stop there. If you specifically need to only skip the rewrites if it matches existing PHP files then:

RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^(subfolder1|subfolder2)/.+\.php$ - [L] 

If the request if for /subfolder1/<something>.php and that file exists then stop here.

UPDATE#1:

We only want this to apply to PHP files in /public_html, and none of its subfolders

You could probably still do this with an exception before your existing rules. If the request contains a slash (ie. it's for a subfolder) then abort. For example:

RewriteRule /.*/?$ - [L] 

Alternatively, change the pattern in your existing RewriteRules to match anything except a slash (ie. [^/]*) instead of literally everything (ie. .*). Applied to your existing rules:

RewriteRule ^([^/]*)\.php$ /$1/ [L,R=301] : RewriteRule ^([^/]*)/$ $1.php [L] : RewriteRule ^[^/]*$ $0/ [L,R=301] 

UPDATE#2: Added anchors to the above RewriteRule patterns.

UPDATE#3: To make the above apply to only specific files in the document root. You would use an exception (as in the above) that excludes all other files. For example:

RewriteRule !^(file1|file2|file3|file4) - [L] 

In order to allow all URLs that start /file1, /file2, /file3, etc. (The URL matched by the RewriteRule pattern does not start with a slash in per-directory .htaccess files.)

In context...

Options -MultiViews RewriteEngine On # Only allow specific requests to be processed... RewriteRule !^(file1|file2|file3|file4) - [L] # Remove .php extension RewriteCond %{THE_REQUEST} ^GET\ /[^?\s]+\.php RewriteRule (.*)\.php$ /$1/ [L,R=301] # Force trailing slash RewriteCond %{REQUEST_FILENAME}.php -f RewriteRule .*[^/]$ $0/ [L,R=301] # Route request... RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} ^/(.+)/$ RewriteCond %{DOCUMENT_ROOT}/%1.php -f RewriteRule ^(.*)/$ $1.php [L]
