What is the best practice for checking if an object has been created in PHP classes?

When working with PHP classes, it is common to need to check if an object has been created before accessing its properties or methods. The best practice for checking if an object has been created is to use the `isset()` function to verify if the object variable is set and not null. 

class MyClass {
    private $property;

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

$myObject = new MyClass('example');

// Check if object has been created
if (isset($myObject)) {
    // Object exists, can access properties and methods
    echo $myObject->property;
} else {
    // Object does not exist
    echo "Object not created";
}
