does anyone know what does &$this mean? I saw this on the php.net tuturial
for references inside a constructor.
I thought that $this is already a reference?
The way it was used :
class Foo
{
function Foo($name)
{
// create a reference inside the global array $globalref
global $globalref;
$globalref[] = &$this;
// set name to passed value
$this->setName($name);
// and put it out
$this->echoName();
}
thanks for any input!
