inheritence

do subclasses inherit their baseclass's contstructor method?

No, not in PHP.

well i think it might...the final line of this code echos true....
<?php
class Calculator
{
// Private variable
//
var $value;

//Accessor functions
//
function setValue( $value )
{
    $this->value = $value;
}
function getValue()
{
    return $this->value;
}
function addValue( $value )
{
    $this->value += $value;
}

// Constructor function
//

function Calculator()
{
    $this->value = 0;
}

// Other functions
//
function add( $number1, $number2 )
{
    return $number1 + $number2;
}
function subtract( $number1, $number2 )
{
    return $number1 - $number2;
}
function multiply( $number1, $number2 )
{
    return $number1 * $number2;
}
function divide( $number1, $number2 )
{
    return $number1 / $number2;
}

}
class randy extends calculator
{

}
$Calculator=new RANDY();
echo isset($Calculator->value);
?>

Now that I re-read your question, I misinterpreted it earlier. It does inherit the constructor, but the parents constructor is not called automatically. You have to call it from within the derived class.

I think the appropriate saying here is 'My bad!' ;o)
