Turn mod_rewrite rules into PHP rules - php

Question

I want to be able to handle mod rewrites from within PHP instead of my .htaccess file, this way when I have custom modules that need a new rewrite I don't have to redo the .htaccess file.
I want to mimic the way that WordPress does their .htaccess which is:
RewriteEngine On RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ /index.php/$1 [L,QSA]
My current .htaccess is this:
Options +FollowSymlinks
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# MBP Rules
RewriteRule ^module/([A-Za-z-_]+)/([A-Za-z-_]+)/?$ /index.php?p=module&prefix=$1&module_page=$2 [NC,QSA,L]
RewriteRule ^module/([A-Za-z-_]+)/([A-Za-z-_]+)/([A-Za-z-_]+)/?$ /index.php?p=module&prefix=$1&module_page=$2&page=$3 [NC,QSA,L]
RewriteRule ^module/([A-Za-z-_]+)/([A-Za-z-_]+)/([0-9]+)/?$ /index.php?p=module&prefix=$1&module_page=$2&id=$3 [NC,QSA,L]
RewriteRule ^([A-Za-z-_]+)/?$ /index.php?p=$1 [NC,QSA,L]
RewriteRule ^([A-Za-z-_]+)/([A-Za-z-_]+)/?$ /index.php?p=$1&s=$2 [NC,QSA,L]
RewriteRule ^([A-Za-z-_]+)/([A-Za-z-_]+)/([0-9]+)/?$ /index.php?p=$1&s=$2&id=$3 [NC,QSA,L]
Does anyone know how to make this happen?

Answer 1

My way is to replace
RewriteRule ^(.+)$ /index.php/$1 [L,QSA]
With
RewriteRule ^(.+)$ /index.php?path=$1 [L,QSA]
Then you have to do similar parsing and everything as modrewrite does, but you can do it yourself using preg_match on $_GET['path']. I.e.
if (preg_match('/id/([0-9]*)', $_GET['path'], $matches)) {
Do code;
}

Sure, have the .htaccess file look like the first example you have, and build your script from there.
Probably write some sort of Router class, to route the requests to their places, the fundamentals being splitting the received query by /, which gives you an array of URL parts, and start conditioning.
