What are common pitfalls to avoid when accessing object properties in PHP OOP?

One common pitfall to avoid when accessing object properties in PHP OOP is directly accessing private or protected properties outside of the class. To solve this, you should create getter and setter methods within the class to access and modify these properties. This ensures proper encapsulation and data integrity. 

class Example {
    private $property;

    public function getProperty() {
        return $this->property;
    }

    public function setProperty($value) {
        $this->property = $value;
    }
}

$example = new Example();
$example->setProperty('value');
echo $example->getProperty(); // Output: value
