If a constructor is not present in a child class, php5 will try to call a constructor from the
parent class. This behaviour can be used to somewhat simulate constructor chaining.
<?php
abstract class Parent {
function __construct()
{
echo "Parent constructor called\n";
$this->myConstruct();
}
}
class Child extends Parent {
function myConstruct()
{
echo " Child 'contructor' called";
}
}
$c = new Child();
?>
will output:
Parent constructor called
Child 'constructor' called
