I revised this example to give a better feel for the scope and overloading rules in PHP 4.
<?php
class A {
function example() {
echo "I am the original function A::example().<br />\n";
$this->other();
}
function other() {
echo "I am the original function A::other().<br />\n";
}
}
class B extends A {
function example() {
echo "I am the redefined function B::example().<br />\n";
A::example();
}
function other() {
echo "I am the redefined function B::other().<br />\n";
}
}
// there is no object of class A.
// this will print
// I am the original function A::example().<br />
// PHP Fatal error: Call to a member function on a non-object in test.php on line 5
A::example();
// create an object of class B.
$b = new B;
// this will print
// I am the redefined function B::example().<br />
// I am the original function A::example().<br />
// I am the redefined function B::other().<br />
$b->example();
?>
