You need to do:
$objCar[0]->m_sColor == 'Blue'; // or is it Blauw ?
when outside of the class and refering to the class.
$this->m_sColor = 'Blue'; // or is it Blauw ?
when inside the class refering to the class itself
---
class clsCar
{ // php3/4 style
var $m_sMake = '';
var $m_sModel = '';
var $m_sColor = '';
function clsCar($args = array())
{ // called whenever you create the class in your script as are the
variable set above
if (isset($args[0]))
{
$this->m_sMake = $args[0];
}
if (isset($args[1]))
{
$this->m_sModel = $args[1];
}
if (isset($args[2]))
{
$this->m_sColor = $args[2];
}
}
}
