Retrieve information from URL string 1

[CassidyHunt]

I know in ASP or ASP.Net you can get variables from the url by using Request.Querystring("VariableName").

Right now I am trying to check if a variable exists in the URL and if it does make a decision on that for what to show.

Currently I have this setup:

if(is_null($_GET['u']))
{
//Do this
}
else
{
//Do this
}

When the page appears and u variable is not present I get an indexing error. I do not want use a form or post method. I would like to be able to just place it in a hyperlink and test for it.

Any help would be greatly appreciated.

You want to use

if (isset($_GET['x']))

to check for existence.
