How can PHP developers effectively balance between static and non-static variables and methods in their code to ensure better code organization and maintainability?

To effectively balance between static and non-static variables and methods in PHP code, developers should consider the scope and purpose of each element. Static variables and methods can be useful for shared data or functionality across all instances of a class, while non-static elements are specific to each instance. By carefully organizing and categorizing variables and methods as static or non-static based on their usage, developers can improve code organization and maintainability.

class Example {
    private static $staticVar;
    private $nonStaticVar;

    public static function setStaticVar($value) {
        self::$staticVar = $value;
    }

    public function setNonStaticVar($value) {
        $this->nonStaticVar = $value;
    }
}
