Php server

Hello,
What is the different between
$_SERVER['SERVER_NAME'];
and
$_SERVER['HTTP_HOST'];
?

thanks

 

$_SERVER[HTTP_HOST] is derived from the incoming HTTP request.But $_SERVER[SERVER_NAME] is the predefined name of the server in the configuration file.Generally this is the name of the server under which a PHP script is being executed. Also $_SERVER[HTTP_HOST] refers to the headers from the current request, if any. Hope this helps you.

 

$_SERVER['SERVER_NAME'] is based on your web servers' config file (Apache2 in my case), and varies depending on a few directives: (1) VirtualHost, (2) ServerName, (3) UseCanonicalName, etc.

$_SERVER['HTTP_HOST'] is based on the request from the client.

 

So which one is better to use if I want to get the domain name of my website?

 

Use $_SERVER['HTTP_HOST'] to get the domain name of the site you want.

 

Ok
thanks...
