What are the best practices for handling multiple domains on a single web server in PHP?

When handling multiple domains on a single web server in PHP, it is best practice to use virtual hosts to separate the different domains and their corresponding directories. This ensures that each domain has its own isolated environment and prevents conflicts between them. Additionally, using a configuration file to map each domain to its respective directory can help streamline the setup process. 

// Example of setting up virtual hosts for multiple domains in Apache configuration file (httpd.conf or apache2.conf)

<VirtualHost *:80>
    ServerName www.domain1.com
    DocumentRoot /var/www/domain1
</VirtualHost>

<VirtualHost *:80>
    ServerName www.domain2.com
    DocumentRoot /var/www/domain2
</VirtualHost>
