SERVER_ADDR undefined index

Question

Hey,

I am getting an undefined index on my config page and it reads:

Notice: Undefined index: SERVER_ADDR in inc/config .inc.php on line 3

Any idea on how I can fix that? I know its warning, but would still like to get at it. I am using it to check for the address whether to use my local or remote config settings.

Thanks,

Ryan

Answer 1

Have you tried getenv?

getenv('SERVER_ADDR')

Answer 2

You seem to be looking for $_SERVER["SERVER_ADDR"] in IIS which is not defined there.

Try $_SERVER['HTTP_HOST'] instead, it is set always as long as you force HTTP 1.1

Answer 3

If you haven't done so, make sure you're accessing SERVER_ADDR using the $_SERVER array to obtain the value of SERVER_ADDR, which is an element of this array.

$_SERVER['SERVER_ADDR'];

If that doesn't work, it may mean that your server doesn't provide that information.

From PHP.net:

There is no guarantee that every web server will provide any of these; servers may omit some, or provide others not listed here.

Hope that helps.

Answer 4

Hey All,

I am using it in this context:

if ($_SERVER['SERVER_ADDR'] == '127.0.0.1' || $_SERVER['SERVER_NAME'] == 'localhost') {        

}
