I am trying to hide the extension of .php file from the link

for example www.example.com/about.php To display www.example.com/about

what I did

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php [NC,L] 

and It works perfectly.

but I have another link which example.com/news.php?id=45 according to the above rule, I can access the link like

example.com/news?id=45 without .php

but I want to hide id=45 I want it like this example.com/news/45

what I did RewriteRule ^news.php?id=([0-9] ) /news/$1 [NC,L]

But It won't work I got 500 Internal Server Error

CodePudding user response：

Try it like this instead:

# MultiViews must be disabled for "/news/45" to work
Options -MultiViews

RewriteEngine on

# Rewrite "/news/45" to "news.php?id=45"
RewriteRule ^news/(\d )$ news.php?id=$1 [L]

# Handle extensionless ".php" URLs
RewriteCond %{REQUEST_URI} !\.\w{2,3}$
RewriteCond %{DOCUMENT_ROOT}/$1.php -f
RewriteRule (.*) $1.php [L]

Your 500 Internal Server Error was actually caused by your original directives that "hide" the .php extension, not your "new" directive (that wasn't actually doing anything). Your original directives would have rewritten a request for /news/45 to /news/45.php to /news/45.php.php etc. creating a rewrite-loop (500 error).

See my answer to the following question on ServerFault with a detailed explanation of this behaviour: https://serverfault.com/questions/989333/using-apache-rewrite-rules-in-htaccess-to-remove-html-causing-a-500-error

The logic of this directive is reversed and would never actually match the requested URL (or anything for that matter), so won't actually do anything. It is, however, syntactically OK, so won't trigger an error.

The 500 error would have occurred simply by requesting /news/45 (with your original directives), whether this directive was in place or not.
