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

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']; }

The question is probably too broad to be reasonably answered. When we're done with the multitude of yesreasons and the multitude of no reasons there are still the myriads of opinions and styles ;-) — VolkerK

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();
