Are there any specific best practices for declaring variables in PHP classes?

When declaring variables in PHP classes, it is considered a best practice to explicitly declare the visibility (public, private, protected) of the variables. This helps to clearly define the scope of the variable and can prevent unintended access or modification. Additionally, it is recommended to initialize variables with default values to ensure predictable behavior. 

class MyClass {
    public $publicVar = 'public';
    private $privateVar = 'private';
    protected $protectedVar = 'protected';
    
    public function __construct() {
        // Constructor code here
    }
}
