How can variables be passed between different methods of the same class using getters and setters in PHP?

To pass variables between different methods of the same class in PHP, we can use getters and setters. Getters are used to retrieve the value of a private property, while setters are used to set the value of a private property. By using getters and setters, we can ensure that the variables are accessed and modified in a controlled manner within the class. 

class MyClass {
    private $myVariable;

    public function setMyVariable($value) {
        $this->myVariable = $value;
    }

    public function getMyVariable() {
        return $this->myVariable;
    }

    public function doSomething() {
        // Access the variable using the getter
        $value = $this->getMyVariable();
        
        // Modify the variable using the setter
        $this->setMyVariable($value + 1);
    }
}

$myObject = new MyClass();
$myObject->setMyVariable(10);
$myObject->doSomething();
echo $myObject->getMyVariable(); // Output: 11
