Most efficient way of accessing a private variable of another class? - php

Question

There are many methods around that allow you to access private variables of another class, however what is the most efficient way?
For example:
I have this class with some details in:
class something{
private $details =
['password' => 'stackoverflow',];
}
In another class I need to access them, example (although this obviously wouldn't work since the variable isn't in scope to this class):
class accessSomething{
public function getSomething(){
print($something->details['password']);
}
}
Would a function like this be good enough within the class "something" to be used by the access class?:
public function getSomething($x, $y){
print $this->$x['$y'];
}

Answer 1

you should be using proper getters/setters in your classes to allow access to otherwise restricted data.
for example
A class
class AClass {
private $member_1;
private $member_2;
/**
* #return mixed
*/
public function getMember1() {
return $this->member_1;
}
/**
* #param mixed $member_1
*/
public function setMember1( $member_1 ) {
$this->member_1 = $member_1;
}
/**
* #return mixed
*/
public function getMember2() {
return $this->member_2;
}
/**
* #param mixed $member_2
*/
public function setMember2( $member_2 ) {
$this->member_2 = $member_2;
}
}
which is then called as follows:
$newClass = new AClass();
echo $newClass->getMember1();
echo $newClass->getMember2();
