What does this do?

function getuserlanguage() {
return $this->_userlanguage ;
}

Not $this, but the symbol _userlanguage
and the -> before it.

My PHP book does not use or discuss either of these symbols. If someone could tell me what the whole function does and those two symbols too, it sure would be great.

Thanks

Suppose you have class like this

class myclass {

   var $_userlanguage;

   function myclass() {
              // set default value
          $this->_userlanguage = 'en';
   }

   // method to get the language var

   function getuserlanguage() {
           return $this->_userlanguage ;
   }
} 

Then

$obj = new myclass;

echo $obj->getuserlanguage();

--> en
