Remove .php from URL - Specific case - php

Question

This is my .htaccess file, everything works so far but I can't manage to remove .php extension from files, every code that I tried from other answers just threw 500 or 404 error. Please advise where and what to add. Structure of the folders is localhost/myfolder/somefile.php
Just to be clear - localhost/myfolder/ is a root for my project.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ /myfolder/$1/ [L,R=301]
RewriteRule ^team-news/([0-9]+[/])?$ posts.php?p=$1&cat=Team\ News
RewriteRule ^product-news/([0-9]+[/])?$ posts.php? p=$1&cat=Product\ News
RewriteRule ^member-specials/([0-9]+[/])?$ posts.php?p=$1&cat=Member\ Specials
RewriteRule ^ambassador-blogs/([0-9]+[/])?$ posts.php?p=$1&cat=Ambassador\ Blogs
RewriteRule ^user/([0-9]+[/])?$ profile.php?id=$1
RewriteRule ^browse-all/([0-9]+[/])?$ searchall.php?p=$1
RewriteRule ^edit/([0-9]+[/])?$ edit.php?id=$1
RewriteRule ^articles/([0-9]+[/])?$ post.php?id=$1

Answer 1

This snippet will allow you to rewrite to remove php extensions:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]
If you want your URL to have a trailing /, you can use this snippet:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/$ $1.php
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=301,L]

Answer 2

Removing extension, say; php or html in browser will let browser find it a little bit more effort to find the source file. if you need it so, this follows may help you:
UPDATED:
PHP:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)/$ /$1.php
HTML:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.html -f
RewriteRule ^(.*)/$ /$1.html
those will remove all extensions in your files (both php and html).
Note: see if server enables mod rewrite module/extension.

You should be using two .htaccess files. The first should go in your localhost root (to redirect requests to myfolder), and the second should go into myfolder (to match up routes against your PHP files):
Root .htaccess:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ /myfolder/$1/ [L,R=301]
myfolder .htaccess:
RewriteEngine On
RewriteBase /myfolder/
RewriteRule ^team-news/([0-9]+[/])?$ posts.php?p=$1&cat=Team\ News [L]
RewriteRule ^product-news/([0-9]+[/])?$ posts.php?p=$1&cat=Product\ News [L]
RewriteRule ^member-specials/([0-9]+[/])?$ posts.php?p=$1&cat=Member\ Specials [L]
RewriteRule ^ambassador-blogs/([0-9]+[/])?$ posts.php?p=$1&cat=Ambassador\ Blogs [L]
RewriteRule ^user/([0-9]+[/])?$ profile.php?id=$1 [L]
RewriteRule ^browse-all/([0-9]+[/])?$ searchall.php?p=$1 [L]
RewriteRule ^edit/([0-9]+[/])?$ edit.php?id=$1 [L]
RewriteRule ^articles/([0-9]+[/])?$ post.php?id=$1 [L]
Note how I have also included [L] to stop it from doing anything else once it has found a match.

Just below your 301 rule add this rule:
RewriteEngine On
RewriteBase /myfolder/
# To externally redirect /dir/file.php to /dir/file
RewriteCond %{THE_REQUEST} \s/+(.+?)\.php[\s?] [NC]
RewriteRule ^ %1 [R=302,L,NE]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}\.php -f [NC]
RewriteRule ^(.+?)/?$ $1.php [L]
