    To answer your question:

    In PHP, you can get the current domain name using a combination of the $_SERVER superglobal array. Here are some common methods:

    Method 1: Using $_SERVER['HTTP_HOST']

    This is the most common way to retrieve the domain name.

    $domain = $_SERVER['HTTP_HOST'];
    echo $domain;
    

    Method 2: Using $_SERVER['SERVER_NAME']

    This method also retrieves the domain name but it's based on the server configuration.

    $domain = $_SERVER['SERVER_NAME'];
    echo $domain;
    

    Notes:

    • $_SERVER['HTTP_HOST'] gets the domain name as it appears in the user's browser, so it reflects the domain name entered by the user.
    • $_SERVER['SERVER_NAME'], on the other hand, is defined in the server configuration and may not always match the domain name seen by the user, especially if you are using virtual hosts.
    • Ensure that you have considered security implications, as the $_SERVER variables can be manipulated by the user.

    These methods should cover most scenarios for retrieving the current domain name in a PHP environment. Remember to choose the method that best fits your particular use case.
