What are best practices for declaring properties and methods in PHP OOP to avoid errors?

When declaring properties and methods in PHP OOP, it is best practice to ensure proper visibility (public, private, or protected) and to use access modifiers to control access to these elements. This helps prevent unintended access or modification of class members and promotes encapsulation. Additionally, it is important to follow naming conventions and avoid duplicate declarations to prevent errors in your code. 

<?php
class MyClass {
    private $privateProperty;
    protected $protectedProperty;
    public $publicProperty;

    private function privateMethod() {
        // method implementation
    }

    protected function protectedMethod() {
        // method implementation
    }

    public function publicMethod() {
        // method implementation
    }
}
?>
