Example#1 implies that get_class() will return the name of the object variable when in fact it
returns the class name of which the object is an instance.
So:
<?php
class A
{
function foo()
{
if (isset($this)) {
echo '$this is defined (';
echo get_class($this);
echo ")\n";
} else {
echo "\$this is not defined.\n";
}
}
}
class B
{
function bar()
{
A::foo();
}
}
$a = new A();
$a->foo();
A::foo();
$b = new B();
$b->bar();
B::bar();
?>
Will actually output:
$this is defined (A)
$this is not defined.
$this is defined (B)
$this is not defined.
A subtle but critical difference.
