Use directories in url as php variables - php

Question

I am after a way of using the directories in the URL as PHP variables. Similar to Wordpress (if not all blogging platforms) I want a way to, say, pass domain.com/directory into a php file.
The reason for this is so that when I create my own blog things, the URLs will be SEO friendly.
Forexample, instead of
domain.com/?blog=1&foo=1&bar=1&foobar=5
I want
domain.com/1/1/1/5 or something
where I can then use the explode function to get variables.

Answer 1

RewriteEngine On
RewriteRule ^([^/]*)/([^/]*)/([^/]*)/([^/]*)$ /?blog=$1&foo=$2&bar=$3&foobar=$4 [L]
There's a lot of generators on google, search it and stackoverflow about rewrite rules, you'll find a lot of info.

Answer 2

For that functionality in php, you need mod_rewrite or the equivalent in your webserver of choice, and to rewrite the url path into a get param instead.
Google "clean urls drupal", for an example of it in the wild.

Answer 3

RewriteEngine On
RewriteRule ^(.*)$ /index.php?url=$1 [L]
then in your index.php you can do explode, regular expresions or whatewer you want with $_GET['url']
or you can skip files that alredy exists like css or javascript and image files
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^(.*)$ /index.php?url=$1 [NC,L]

Answer 4

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)/(.*)/(.*)/(.*)$ ?blog=$1&foo=$2&bar=$3&foobar=$4 [PT,L]
I think this ought to work for your case specifically. The (.*) groups one or more characters of any type separated by a /. In this case you'll get them as GETs with the keys e.g foo
Otherwise as a string for exploding:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ blog.php?string=$1 [PT,L]
Assuming there's a blog.php file in the same directory to process the string
Hope it helps
