It refers to the object upon which the class method was called. So
outside of the class you might have:
$foo = new FooClass();
$foo->doSomething();
then inside the class you might have the following:
class FooClass
{
function doSomething()
{
$this->doSomethingElse();
}
function doSomethingElse()
{
$foo = 1;
return (++$foo === $foo++); // ;)
}
}
Cheers,
Rob.
