best way to update class variables

[ober]

I am making a new product display class and I have all kinds of settings that are seperate variables within the class.  Is there an easy way to update these values without creating a ton of small functions like this:
[code]
<?php
function update_headerbgcolor($color)
{
      this->headerbgcolor = $color;
}
?>[/code]

Any help appreciated.

Nevermind... I'm an idiot.  I forgot I could do $objectname->varname = x outside of the class.

And even if that weren't possible..

[code]<?php
function update_property($property, $value)
{
  $this->$property = $value;
}
?>[/code]

EDIT: Correction

With PHP4 you can just set with
[code]
$obj->var = $value.[/code]

Same goes for PHP5 public variables

For PHP5 private vars you can define a "magic function"
[code]
function __set ($var , $value) {
    $this->$var = $value;
}[/code]

which will then allow
[code]$obj->privateVar = $value;[/code]

Eh... I'm stuck with PHP4 for this client.  I think I'll go with the first method, but I hadn't thought of passing the property and the value... the client will be updating these, so I'm trying to keep it as simple as possible.
