Access classes by variable variables

[GrodanBoll]

Hi 🙂

Why doesn't this work?

class balle
{
	var $balle1 = 1;
	var $balle2 = 2;

function getBalle ()
{
	return $this -> balle1;

}

}

$b = new balle();
$ggg = "b -> getBalle ()";
echo "Meeeeeen: ".${$ggg}.".<br />";

I don't get any output.

I think that the class method operator and the paren's are getting evaluated as part of the variable name. Not sure though.

<?php
class balle 
{ 
    var $balle1 = 1; 
    var $balle2 = 2; 

function getBalle() 
{ 
    return $this->balle1; 
} 
} 
$b = new balle(); 
$g = "b"; 
$h = "getBalle";
echo $$g->$h();
?>

Thx Shrike.
That got the output right but not, I'm sorry to say, in a way i'd like it to be handled.

<?php
class balle 
{ 
    var $balle1 = 1; 
    var $balle2 = 2; 

function getBalle() 
{ 
    return $this->balle1; 

} 

} 

$b = new balle (); 

$g = "b -> getBalle ()"; 

eval ("$var = $".$g.";");

echo $var;
?> 

This is the way I'd whant it to behandled. 🙂

Thx again Shrike. 🙂

Hi,

this might be another way:

$b = new balle ();  

$var = $b->getBalle();
echo $var;

Is there a reason you want to use variable variables in this case ?

Ah yes, the normal way. 😉

Jupp, I have areason to use variable variables. In the run-time I don't know what function to use.
So instead of a lot of if's, I'm tyring to use variable variables.
