Undefined variables issues

Help !

What am I missing here ??

I have the following:

PHP Code:


		
			
class Test

{

  var $var1;

  

  function Set($var1)

  {

     $this->$var1 = $var1;

  }

  function Show()

  {

    echo $this->$var1;

  }

}



$Test = new Test();

$Var = 1;

$Test->Set($Var);

$Test->Show()

and I get a Undefined Variable var1 ... cannot access empty property .... error message for the line

$this->$var1 = $var1;

Any ideas anyone .... thanks in advance

php Code:

class Test
{
  var $var1;
  
  function Set($var1)
  {
     $this->var1 = $var1;
  }
  function Show()
  {
    echo $this->var1;
  }
}

The only thing you did wrong was you had $this->$var1, instead of $this->var1.

Excellent - thanks very much for that - I missed the fact you need to drop the $ when you use $this-> - I am getting there slowly ! lol
