Htaccess Does not allow third rule - php

Question

I have two rules in my htaccess file and while the first two are working I can't figure out why the third one isn't.
What I have currently is
Options -Indexes
Options +FollowSymLinks
IndexIgnore */*
# Turn on the RewriteEngine
RewriteEngine On
# Rules
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([a-zA-Z0-9]+)$ index.php?key=$1
RewriteRule ^([a-zA-Z0-9]+)/$ index.php?key=$1
RewriteRule ^([a-zA-Z0-9]+)/([a-zA-Z0-9]+)$ index.php?key=$1&id=$2
RewriteRule ^([a-zA-Z0-9]+)/([a-zA-Z0-9]+)/$ index.php?key=$1&id=$2
RewriteRule ^([a-zA-Z0-9]+)/([a-zA-Z0-9]+)$ index.php?key=$1&id=$2&user=$3
RewriteRule ^([a-zA-Z0-9]+)/([a-zA-Z0-9]+)/$ index.php?key=$1&id=$2&user=$3
<files config.php>
order allow,deny
deny from all
</files>
<files loader.php>
order allow,deny
deny from all
</files>
I can go to localhost/page/5 and I can go to localhost/page just fine, but if I try to go to localhost/module/5/1 it breaks and throws me a 404 error.
Any help on this would be greatly appreciated as I don't see anything, so it could be a simple yet stupid typo on my part.

Answer 1

None of your rule regex are matching /module/5/1 URI. Have your rules like this:
RewriteEngine On
# skip all files and directories from rewrite rules below
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(\w+)/?$ index.php?key=$1 [L,QSA]
RewriteRule ^(\w+)/(\w+)/?$ index.php?key=$1&id=$2
RewriteRule ^(\w+)/(\w+)/(\w+)/?$ index.php?key=$1&id=$2&user=$3 [L,QSA]
\w matches [a-zA-Z0-9_]
