How can objects in PHP be treated consistently to avoid unexpected behavior?

To treat objects consistently in PHP and avoid unexpected behavior, it is important to always check if an object property or method exists before accessing or calling it. This can be done using the isset() function for properties and the method_exists() function for methods. By doing this, you can prevent errors and ensure that your code behaves predictably.

class MyClass {
    public $property;

    public function myMethod() {
        if (isset($this->property)) {
            // do something with $this->property
        }

        if (method_exists($this, 'anotherMethod')) {
            $this->anotherMethod();
        }
    }

    public function anotherMethod() {
        // method implementation
    }
}
