Count ?var in PHP url as true

I have seen some urls on facebook where at the end you see &theater I assume this means it's somehow setting theater to true. I was wondering how to accomplish the same thing.

For instance:

example.com/page/?var

In this url, var would be set true.

I know I can add =true to the end of it to make it have the desired value, but I am asking this for convenience.

$var = isset($_GET['var']);

Now $var is a boolean variable.

You can use

if(isset($_GET['var'])){
 // true if var is set, even if it is empty
}

It is seen as a syntax error when one starts to declare $_GET['var'] when it is not set. PHP will throw an error at you, when error reporting set. It is good to see if it is set in the first place. If the var is oly to flag "true", then that is accomplished by just setting it. To accomplish setting a url with $_GET variables is just by adding them to a link the way you see them in the address bar.
