Getting rid of GET keys parameters in the URL, keep only values - php

Question

I wanna to get rid of GET string parameters, from keys.
For example this is initial uri:
http://example.com/api/get_users_method?user_age_from=18&user_age_to=25&user_city=ohio
http://example.com/api/get_users_method?user_age_from=18&user_age_to=25
http://example.com/api/get_users_method?user_city=ohio
I wanna make like this:
http://example.com/api/get_users_method/18/25/ohio
http://example.com/api/get_users_method/18/25
http://example.com/api/get_users_method/ohio
How can i get this result? I found some solution, to edit htaccess file, but it doesn't work unfortunately, maybe i made some mistakes in htacces file? I'm using php. Thanks!

RewriteRule ^([^/]+)/([^/]+)/([^/]+)$ /api/get_users_method?user_age_from=$1&user_age_to=$2&user_city=$3 [NC,L]
You have to treat the rules separately. All Conditions preceding rules only apply to a single rule. Following rules are not touched by that rule.

Answer 2

You will 3 separate rules in your root .htaccess (a level above api directory)
Options -MultiViews
RewriteEngine On
RewriteRule ^(api/get_users_method)/(\w+)/(\w+)/(\w+)/?$ $1?user_age_from=$2&user_age_to=$3&user_city=$4 [NC,L,QSA]
RewriteRule ^(api/get_users_method)/(\w+)/(\w+)/?$ $1?user_age_from=$2&user_age_to=$3 [NC,L,QSA]
RewriteRule ^(api/get_users_method)/(\w+)/?$ $1?user_city=$2 [NC,L,QSA]
