php class passing fields into functions?

[adrive]

hi, there's something that's been bothering me for some time and im not too sure if there is another way to pass a class's field as a default argument like this :

let's say I have a class known as "Body"

class Body{

 private $myHair = "brown";

 function getHead($defaultHair = $this->myHair){
   ...
 }


}

How can i actually pass Body's own "myHair" field into getHead function as a default value incase user leaves out blank by calling getHead(); ?😕

You can maybe change the code in this:

class Body{ 
  private $myHair = "brown";

  function getHead($defaultHair = NULL) {
    if (is_null($defaultHair))
      $defaultHair = $this->myHair;
  }
}

}

actually...im trying to prevent writing those lines inside the function but as arguments instead if it's possible 😛

Not really; the default value needs to be known at compile time. A const would work.

	const defaultHair = 'brown';

function hair($hair=self::defaultHair)
{
//...
}

oh..well 😛 if its constants it's not gonna fit into the situation. But thanks anyways 😃
