How can the error "Fatal error: Cannot redeclare Konstruktor::__construct()" be resolved in PHP?

The error "Fatal error: Cannot redeclare Konstruktor::__construct()" occurs when trying to declare a constructor method (__construct) in a class that has already been declared. To resolve this issue, you need to check if the constructor method already exists before declaring it in the class.

if (!function_exists('Konstruktor::__construct')) {
    class Konstruktor {
        public function __construct() {
            // Constructor code here
        }
    }
}
