What are the potential reasons for not being able to access a property within an object using $this->property in PHP?

If you are unable to access a property within an object using $this->property in PHP, it could be due to the property being declared as private or protected in the class. To access these properties from outside the class, you can create getter and setter methods within the class to retrieve or modify the property values. 

class MyClass {
    private $property;

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

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

$obj = new MyClass();
$obj->setProperty("Hello World");
echo $obj->getProperty(); // Output: Hello World
