I am very confused about how using & operator to reduce memories.
Can I have an answer for below question??
clase C{
function B(&$a){
$this->a = &$a;
$this->a = $a;
//They are the same here created new variable $this->a??
// Or only $this->a = $a will create new variable?
}
}
$a = 1;
C = new C;
C->B($a)
Or maybe my understanding is totally wrong.....
