if the class B that extends class A does not have a constuctor function (i.e. a function named B),
then the constructor function of A will be used instead, you don't need to make a constructor
in B just to call the constructor of A.
For example:
<?php
class A
{
function A()
{
echo "HEY! I'm A!\n";
}
}
class B extends A
{
}
$b = new B();
?>
produces the output:
HEY! I'm A!
