How to reference a variable within a function within a class?

[jdlev]

Let's say I wanted to pull the host & address variables out of the function "ip" and echo them outside of the class. How would I go about doing that?  I tried in the code below and failed miserably

<?php
//Returns information on the User's IP Address, Hostname, Port, and Username

class getIP
 
{
	public function ip() { 
						$this->address = $_SERVER['REMOTE_ADDR'];
						$this->host = $_SERVER['REMOTE_HOST'];
						}
	
}

$addy = new getEm;
echo $addy->ip(this->address) . "</br>";

?>

Most class design articles tell you that you should setup functions to "get" and "set" class-based vars.  So - sounds like you simply need a function that returns the values you want.  And then you echo them.

So you can't call multiple variables from a function within a class?  You need to make a function for each variable you want, and just call the function itself?

Well your function is setting the class vars so you need to call the function and then echo the vars.

$addy = new getIP;
$addy->ip();
echo $addy->address;

Not sure of your intent but probably more like this to set on instantiation:

class getIP {
    private $address = '';
    private $host = '';

    function __construct() {
        $this->address = $_SERVER['REMOTE_ADDR'];
        $this->host = $_SERVER['REMOTE_HOST'];
    }

    function __get($var) {
        return $this->{$var};
    }
}

$addy = new getIP;
echo $addy->address;

I'm a dumbass.  I can't believe I couldn't figure that out.  Thanks for the help, I appreciate it
