What is the best practice for accessing variables within a class in PHP?

When accessing variables within a class in PHP, it is considered a best practice to use getter and setter methods to encapsulate the data. This approach helps maintain the integrity of the class by controlling how the variables are accessed and modified from outside the class. By using getter methods to retrieve the variable values and setter methods to update them, you can ensure proper validation and data manipulation. 

class MyClass {
    private $myVariable;

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

    public function setMyVariable($value) {
        // Add validation or manipulation logic here if needed
        $this->myVariable = $value;
    }
}

// Usage
$myObject = new MyClass();
$myObject->setMyVariable('value');
echo $myObject->getMyVariable();
