Aya:
Yes, the example as it stands is pretty useless, and a static method achieves the same result much
more easily. But with a more complicated system, say you have two different ways of doing
"bark":
<?php
class Example1 {
// singleton implementation boilerplate goes here
public function bark() { echo "Woof"; }
}
class Example2 {
// singleton implementation boilerplate goes here
public function bark() { echo "Yap"; }
}
if (/* some condition */)
$method = Example1::singleton();
else
$method = Example2::singleton();
for ($i = 0; $i < 10; $i++) $method->bark();
?>
