In PHP, both $_SERVER[‘HTTP_HOST’] and $_SERVER[‘SERVER_NAME’] are server variables that can be used to retrieve the host name of the current web page. However, they have different meanings and behaviors, as described below:

$_SERVER[‘HTTP_HOST’]: This variable returns the hostname of the requested URL as sent by the client in the HTTP Host header. It can be used to retrieve the domain name of the website that is being accessed by the user. For example, if the user is accessing the URL, $_SERVER[‘HTTP_HOST’] will return the value

$_SERVER[‘SERVER_NAME’]: This variable returns the name of the server host under which the current script is executing. It can be used to retrieve the name of the server that is hosting the website. For example, if the website is hosted on a server with the hostname, $_SERVER[‘SERVER_NAME’] will return the value

In general, $_SERVER[‘HTTP_HOST’] is more commonly used to retrieve the domain name of the website, while $_SERVER[‘SERVER_NAME’] is used to retrieve the name of the server host. However, it is important to note that the behavior of these variables can vary depending on the server configuration, so it is always a good practice to test the values in your specific environment to ensure that they are working as expected.
