I don't know how you would do this on a win system but us nix users, we can use the native hostname with -f to get a reliable hostname.



<?php

$_SERVER["SERVER_NAME"] =  exec('hostname -f');



?>

You can use php_uname("n") in Windows to return the host name. You may have worked this out already but it took my a blinkin age!

It looks like this function isn't available on windows.

Here is my code:

<?PHP

$var = gethostname();

IF ($var===FALSE) {

 echo "The function ran but no results were returned!";

}

ELSE {

 echo "The function returned a value\n\r";

 echo $var;

}

?>

I received  an error:

"Fatal error: Call to undefined function gethostname() "
