hide .php extension & force trailing slash

Question

I've been trying to delete the .php extension and force trailing slashes in the end of the URLs.

I've found an answer to do it exactly what I need at (.htaccess trouble with hiding file extension and forcing trailing slash) but it does not work, I believe it's due to how I am forcing my website to change the document root.

As I do not have access to Virtual Hosts I must change my document root using htaccess, and I have accomplished it by applying the following code..

RewriteCond %{HTTP_HOST} ^site.co$ [NC]
RewriteRule ^(.*)$ http://www.site.co/$1 [R=301,L]
RewriteCond %{REQUEST_URI} !webroot/
RewriteRule (.*) /webroot/$1 [L]

The only working solution that I've been able to apply to hide the .php extension is with the code below.

removing .php extension(only working solution)

RewriteCond %{THE_REQUEST} ^\w+\ /(.*)\.php(\?.*)?\ HTTP/
RewriteRule ^ http://%{HTTP_HOST}/%1 [R=301]

RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule .* $0.php

This code is in the thread that I have linked above, but it does not work on my website as I believe it's due to the document root.

RewriteEngine on

# Forces a trailing slash to be added
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+?[^/])$ /$1/ [R=301,L]

# .php ext hiding
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1.php -f
RewriteRule ^(.+?)/?$ /$1.php [L]

Try these modified rules with different ordering:

RewriteEngine on

# add www before hostname
RewriteCond %{HTTP_HOST} ^site\.co$ [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=302,L,NE]

# if on article page, get slugs and make into friendly url
RewriteCond %{THE_REQUEST} \s/article\.php\?article_uid=([^&]+)&article_title=([^&\ ]+)
RewriteRule ^ /article/%1/%2/? [L,R=302,NE]

# if page with .php is requested then remove the extension
RewriteCond %{THE_REQUEST} \s/+(.+?)\.php[\s?] [NC]
RewriteRule ^ /%1/ [R=302,L,NE]

# Force a trailing slash to be added
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{THE_REQUEST} \s/+([^.]+?[^/.])[\s?] [NC]
RewriteRule ^ /%1/ [R=302,L]

# allow page direction to change the slugs into friendly seo URL
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteRule (?:^|/)article/([^/]+)/([^/]+)/?$ /webroot/article.php?article_uid=$1&article_title=$2 [L,QSA,NC]

# silently rewrite to webroot
RewriteCond %{REQUEST_URI} !/webroot/ [NC]
RewriteRule ^ /webroot%{REQUEST_URI} [L]

# .php ext hiding
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.+?)/?$ $1.php [L]
