I have multiple domains going to the same IP / server (I do shared hosting of multiple domains on my own server). I would like :
http://domain1.com/* => /var/www/domain1/*
http://domain2.com/* => /var/www/domain2/*
Up to now I do it with PHP : all requests are sent to a single PHP file that does the redistribution :
if (strpos($_SERVER['HTTP_HOST'], 'domain1') !== false)
// call the file in /var/www/domain1/*
if (strpos($_SERVER['HTTP_HOST'], 'domain2') !== false)
// call the file in /var/www/domain2/*
I can imagine that there exists a "cleaner" solution without PHP, but just .htaccess ?
What is the best pratice for having multiple domains going to the same server? How should I route the requests from multiple domains to the right directory of the server?
Note : I found this but as there is only 1 upvote, I'm not sure if this is really relevant.

You can use VirtualHosts to route certain sites to directories.
Here's the general configuration I use (in httpd.conf - there's loads of other info here):
<VirtualHost *:80>
ServerName mydomain.example.com
DocumentRoot /var/www/mydomain.example.com
</VirtualHost>
You can also place these directives in different files in /etc/apache2/sites-available/<name>.conf and then do a2ensite <name>, if you're on a system that supports that (Debian/Ubuntu IIRC).
