Why is using "$var = "$obj->prop";" considered bad practice in PHP programming?

Assigning a property of an object directly to a variable using "$var = $obj->prop;" is considered bad practice in PHP programming because it breaks the encapsulation of the object-oriented paradigm. It exposes the internal structure of the object and can lead to unexpected behavior if the property is modified outside of the object's methods. To solve this issue, you should create a getter method within the object class to access the property value. 

class MyClass {
    private $prop;

    public function getProp() {
        return $this->prop;
    }
}

$obj = new MyClass();
$var = $obj->getProp();
