PHP isset not working with blanks

Question

I am just getting back in to PHP after many years and building a basic sit to start things off.

I have an index.php on my root and want to check for input from isset when either the value is ?home or just simply blank.

So easy enough I can start with:

if (isset($_GET['home']))
{
include $_SERVER['DOCUMENT_ROOT'] . '/content.html.php';
}

But my issue is trying to get it to work if there is nothing to get? I can see a couple of ways to do it but I think I am missing something simple to add to the first line.

Any help appreciated.

isset() checks if a variable has a value including ( False , 0 , or empty string) , but not NULL. Returns TRUE if variable exists otherwise returns FALSE.

On the other hand the empty() function checks if the variable has an empty value, empty string , 0, NULL ,or False. Returns FALSE if variable has a non-empty and non-zero value.
