When to use $this->$property

Question

I am having trouble understanding when and why you need to use $this->$property. So adding the $ to both the the this keyword and the property. I have only seen this used within the magic methods __get() and __set(). Can anybody elaborate?

Maybe when the property name is saved in a variable (e.g. $var = "ThisIsMyProperty";) then you use it like this: $this->$var ?! — Rizier123

You can use $this->$property when $property contains a name of a property or $this->$function() when $function contains a function name.

Example:

class MyClass {
    private $email = "[email protected]";

    public function getProperty($p){
        return $this->$p;
    }
}

$obj = new MyClass;
$obj->getProperty("email"); // Returns [email protected]
