Newbie Question - Ignore missing ? links in URL [message #33566]

I'm using links (correct term?) in the URL to pass in data. For example: www.site.com/index.php?phone=555-1212

Everything works fine when I use the following code and pass in a 'phone' value as above.
<?php
$ph = $_GET['phone'];
echo $ph;
?>

The problem is I don't always want to require a 'phone' value in the URL. If someone visits the page with: "www.site.com/index.php" I get this error complaining about the attempt to $_GET the 'phone' value when none exists:

Notice: Undefined index: e in p:\WWW\site.com\index.php on line (##)

I'm trying to make the page work (without errors) even if the URL doesn't contain the 'phone' link value it is expecting. I need a way to test if the 'phone' value was passed in with the URL before I try to assign it to a variable. Is this possible?

Thanks for your help! - Robert
