Hm, strange...Maybe the error does not occur on a Windows system (I
have a Linux server)!? And no: I do not include any other File.
Thanks,

I was unable to reproduce this bug. The following code executes as
expected for me (Win2k/Apache PHP 4.1.1):
class Bike {
function Bike() {
echo 'Constructor of class "Bike"<br>';
}
}
class MountainBike extends Bike {
}
$mb = new MountainBike();
class Bike2 {
function Bike2() {
echo 'Constructor of class "Bike2"<br>';
}
}
class MountainBike2 extends Bike2 {
function MountainBike2() {
parent::Bike2();
}
}
$mb = new MountainBike2();
It outputs:
Constructor of class "Bike"
Constructor of class "Bike2"
with no compile errors. Double check that you aren't including a wrong
file, etc.

In the documentation
(http://www.php.net/manual/en/language.oop.constructor.php) you defined
the following rule:
"If a class has no constructor, the constructor of the base class is
being called, if it exists"
This worked in PHP 4.0.6 for me. After upgrading to Version 4.1.1, it
doesn't.
Here are my test-scripts. The first one ends up with no output or the
errormessage: "Fatal error: Cannot instantiate non-existent class:
mountainbike in
/www/testOO.php on line 15".
actually, the behaviour seems to be undefined.
The second one works, as it should be, but only because of actively
calling the constructor of the base class.
FIRST:
<?php
class Bike {
function Bike() {
echo 'Constructor of class "Bike"';
}
}
class MountainBike extends Bike {
}
$mb = new MountainBike();
?>
SECOND:
<?php
class Bike {
function Bike() {
echo 'Constructor of class "Bike"';
}
}
class MountainBike extends Bike {
function MountainBike() {
parent::Bike();
}
}
$mb = new MountainBike();
?>
