htaccess to be used only in one folder - php

Question

I've just started to use .htaccess and i'm having an issue here.
Inside my public_html folder i have these files.
index.php
profile.php
test.php
.htaccess
And when i go to profile.php file i have some parameters.
http://website.com/profile.php?id=1&name=Doe
For showing better SEO links i'm trying to make it appear like this
http://website.com/1/Doe
with this rewrite condition
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ profile.php?url=$1 [QSA,L]
</IfModule>
depended on this answer (click here)
and then in my php file i get the id of the user so i can make the queries etc with this code
$path_components = explode('/', $_GET['url']);
$ctrl=$path_components[0];
But the thing is that if i do so every file in my folder is trying to make the Rewrite Rule but i want a specific file... the profile.php one.
EDiT 1:
So from the comment below i made this htaccess file, and regardless the mod_rewrite is enabled on my server, the link is not changing at all.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/profile.php$ [NC]
RewriteRule ^([^/.]+)/([^/.]+)(?:/)?$ /profile.php?id=$1&name=$2 [L]
</IfModule>
And my php file now..
$path_components = explode('/', $_GET['id']);
$ctrl=$path_components[0];
But the link
http://website.com/profile.php?id=1&name=Doe
is not changing at all.

Answer 1

You need to redirect your old url to the new one, put this above your existing rule
RewriteEngine on
RewriteCond %{THE_REQUEST} /profile\.php\?id=([0-9]+)&name=(.+)\sHTTP [NC]
RewriteRule ^ /%1/%2? [L,R]
RewriteRule ^([^/]+)/([^/]+)/?$ /profile.php?id=$1&name=$2 [L]

Hello the issue is simple: you should exclude existing files/folders from rewriting process.
I would recommend to have only one index.php page where you get all the request and process in one place. Anyway your working htaccess file should look like this:
<IfModule mod_rewrite.c>
RewriteEngine On
# exclude real folders/files
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
#RewriteRule ^ index.php [L] - # redirect anything to index
# for your version
RewriteRule ^(.*)$ profile.php?url=$1 [QSA,L]
</IfModule>
