how to create subdomains in apache(xampp) server?

Try this :

NameVirtualHost 127.0.0.1:80<VirtualHost *:80><Directory "C:\path\to\ecommerce">    Options FollowSymLinks Indexes    AllowOverride All    Order deny,allow    allow from All</Directory>ServerName ecomm.localhostServerAlias www.ecomm.localhostDocumentRoot "C:\path\to\ecommerce"</VirtualHost>

Yes you edited your hosts file correctly.

In addition to atabak's answer:

Go to Apache > Conf > Extra -> "httpd-vhosts.conf" file and add:

<VirtualHost *:80>DocumentRoot "C:/xampp/htdocs/subdomain"ServerName subdomain.localhost.com</VirtualHost>

Go to C:\WINDOWS\system32\drivers\etc -> "hosts" file and add:

127.0.0.1 subdomain.localhost

from Setting Up Multiple Subdomains Using Xampp/

In xampp\apache\conf\extra\httpd-vhosts.conf file add these line at the bottom of the file for subdomain support :

<VirtualHost *:80>   DocumentRoot "C:/xampp/htdocs/sandbox"   ServerName sandbox.localhost.com</VirtualHost> 

Then in C:\windows\System32\drivers\etc\hosts file add these line at the bottom of the file :

127.0.0.1    sandbox.localhost.com

After that re-start the xampp server and open a new tab, write in the address bar

sandbox.localhost.com

Then you will see the output of index.php file which was in the sandbox folder
