Rewrite a dynamic url after extension removed - .htaccess

Question

I've been working on my HTAccess for a couple days now, and I've hit a dead end.
I've rewritten and redirected the files to be extensionless, now I need to rewrite the url to be SEO Friendly.
Previously, the URL was: http://www.example.com/member.php?playername=encodedName
I removed the extension: http://www.example.com/member?playername=encodedName
I can't quite get it to: http://www.example.com/member/encodedName
Here's what I've gotten so far:
Code trying to redirect to SEO Friendly URL. Does NOT work.
RewriteRule ^member/([^/]*)$ /member.php?playername=$1 [L]
RewriteRule ^squad/([^/]*)$ /squad.php?squadname=$1 [L]
RewriteRule ^article/([^/]*)$ /article.php?articlename=$1 [L]
Unless directory, remove trailing slash. Works.
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [R=301,L]
Resolve .php file for extensionless php urls. Works.
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php [L]
Redirect external .php requests to extensionless url. Works.
RewriteCond %{THE_REQUEST} ^[A-Z]+\ /([^/]+/)*[^.#?\ ]+\.php([#?][^\ ]*)?\ HTTP/
RewriteRule ^(([^/]+/)*[^.]+)\.php $1 [R=301,L]
Does anyone have an idea as to what I am doing wrong? It's probably a very newbie problem that I just haven't encountered yet.

Answer 1

The "Code trying to redirect to SEO Friendly URL" part looks fine. And while you're redirecting requests made directly to php files to remove the extension, you're not doing anything specifically about the 3 SEO friendly URLs that you are rewriting back.
If when you go to http://www.example.com/member/encodedName, and you're not being served the content at http://www.example.com/member.php?playername=encodedName, then this looks like a Multiviews problem. You'll need to turn off Multiviews either in your server/vhost config or add this to the top of the htaccess file (or in the appropriate already existing Options statement):
Options -Multiviews
In order to do the redirecting to the SEO friendly URLs, add this before the "Redirect external .php requests to extensionless url." rules:
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /member\.php\?playername=([^&\ ]+)([^\ ]*)
RewriteRule ^ /member/%1?%2 [L,R=301]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /squad\.php\?squadname=([^&\ ]+)([^\ ]*)
RewriteRule ^ /squad/%1?%2 [L,R=301]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /artcile\.php\?articlename=([^&\ ]+)([^\ ]*)
RewriteRule ^ /article/%1?%2 [L,R=301]
