[SOLVED] Parent Variable as Default Parameter

[seventheyejosh]

Is there any way to do something like this?

 

class a{

     protected $name='Josh';

}

class b extends a{

     function show_name($name=$this->name){

          echo $name;

          }
     }

 

so that if there is no specified value, it'll default to the parent's definition.

 

Thanks.

class b extends a{

     function show_name($name = null){

          if ($name != null)
              echo $name;
          }
          else {
              echo $this->name; 
         }
     }
}

 

That should work

Is there not a more elegant way to do this?

[gevans]

class b extends a{
function show_name($name = null)
{
	echo (is_null($name)) ? $this->name : $name;
}
}

lol I guess that techincally is more elegant, but I meant via the functions parameters.

What do you want to be more elegant about it??

You can only specify a constant value as default for an argument.

Yea I was just getting ready to say that I fixed it by setting it to a class constant:

 

class config{

const server='localhost'; 	//server address
const user='root'; 		//server username
const pass='root'; 		//server password
const db='small'; 		//database name

//stuff

}

class sql extends config{

public function connect($server=parent::server,$user=parent::user,$pass=parent::pass,$db=parent::db){

                $this->disconnect();
	mysql_connect($server,$user,$pass); 	//connect to the server
	mysql_select_db($db);			//select the database

	}//end function connect


//stuff

}
