the above is wrong.

you can declare variable inside class definition using (php4):

var $varname [ = {default value} ];

but it's not necessery. It's good for documentation.

php5 gives you more control with public, protected and private keywords.

outside of class definitions you declare a variable by assigning it a
value, for example:

$myvar = null;

That's it.
