How can scope affect the values accessed by getters and setters in PHP?

Scope can affect the values accessed by getters and setters in PHP if the properties being accessed are not within the same scope as the getters and setters. To solve this issue, make sure that the properties are either public or protected so they can be accessed by the getters and setters. 

class Example {
    private $value;

    public function getValue() {
        return $this->value;
    }

    public function setValue($newValue) {
        $this->value = $newValue;
    }
}

$example = new Example();
$example->setValue(10);
echo $example->getValue(); // Output: 10
