i need some help creating Htaccess - php

Question

i need to hide the extensions of my webpage and also want to let the user put the links in both (lower and upper) case:
Example:
the file name is demo.php
www.example.com/demo
www.example.com/DEMO
www.example.com/Demo
Running PHP in a LAMP server, no access to php.ini, just .htaccess
Actualy im using a file like this:
RewriteEngine On
RewriteBase /
RewriteRule ^/(OUTSOURCING|outsourcing|Outsourcing)$ outsourcing.php [NC,L]
And i m reciving this error:
Not Found
The requested URL /outsourcing was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Answer 1

RewriteEngine On
RewriteBase /
www.example.com/DEMO www.example.com/Demo or doing www.example.com/DEMO/page2
RewriteRule ^/(DEMO|demo|Demo)/(.*)$ demo.php?=$1 [NC,L]
RewriteRule ^/(DEMO|demo|Demo)$ demo.php [NC,L]
RewriteRule ^/(D|d)emo$ demo.php [NC,L]
or pass anything www.example.com/DeMo www.example.com/bob to demo.php
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^([^\.]+)$ demo.php [NC,L]
you may want to test if your allowed .htaccess RewriteRule /*$ http://google.com [R][L]

Answer 2

here is a good way to do it with case insensitive method
EDIT:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ${lc:$1}.php [NC]
this way anything entered will be redirected to a php file.
edit : this way your js and css file can still run

Answer 3

RewriteRule ^/[Dd][Ee][Mm][Oo]/?(.*)$ demo.php [NC,L]
will redirect any capitalization of "Demo" to demo.php

Answer 4

First add this line in the <VirtualHost> section OR at the end of your httpd.conf file (to enable lc function in .htaccess for later use):
RewriteMap lc int:tolower
Then have these rules in .htaccess file:
Options +FollowSymlinks -MultiViews
RewriteEngine on
RewriteCond %{THE_REQUEST} ^GET\s.+\.php [NC]
RewriteRule ^(.+)\.php$ /$1 [NE,R=301,L,NC]
RewriteCond %{REQUEST_URI} !\.php$ [NC]
RewriteCond ${lc:%{REQUEST_FILENAME}}.php -f
RewriteRule . ${lc:%{REQUEST_URI}}.php [L]
First rule in .htaccess is doing external redirect by making a URI of /index.php to /index
Second rule in .htaccess is doing internal redirect by makign a URI of /INDEX to /index.php by lowercasing the URI. Assuming you have filename index.php physically present.
That way you can always write URLs without .php extension.
