How can a PHP developer ensure proper understanding and implementation of OOP principles when encountering errors like the one mentioned in the forum thread?

Issue: One common error when implementing OOP principles in PHP is not properly defining classes and their methods, leading to errors like "Fatal error: Uncaught Error: Call to undefined method". To ensure proper understanding and implementation of OOP principles, developers should carefully define classes, methods, and their relationships. Code snippet: 

class Person {
    private $name;

    public function __construct($name) {
        $this->name = $name;
    }

    public function getName() {
        return $this->name;
    }
}

$person = new Person("John Doe");
echo $person->getName();
