[RESOLVED] By the way of reference .......

Hi anyOne.
I've seen this odd (just for me I think !) code in a class as
constructor

function Authentication(&$db)
{
$this->_DB =& $db;
}

I know the meaning of & (value by reference)
but I don't know the meaning of '=&'
Could you explain me ?
please of course 😃
Take care.

Hello. 🙂

The code isn't complicated, it's just the use of spaces that's confusing. Perhaps this is easier to understand:

function Authentication(&$db)
{
   $this->_DB = &$db;
}

The function accepts the variable $db (which is passed by reference), and sets the "_DB" field for this object to be a reference to $db.

If $db is changed outside the function, $this->_DB gets changed with it.

TKS a lot buddy. 😃
Bye and greetings from Italy 🙂

Thanks, clears some stuff up for me too!
