What are the benefits of categorizing methods and properties as private or public in PHP5?

By categorizing methods and properties as private or public in PHP5, we can control access to these components within a class. Private methods and properties can only be accessed within the class itself, while public methods and properties can be accessed from outside the class. This helps improve code organization, encapsulation, and security by restricting direct access to certain components. 

<?php
class MyClass {
    private $privateProperty;
    public $publicProperty;
    
    private function privateMethod() {
        // do something
    }
    
    public function publicMethod() {
        // do something
    }
}
?>
