This code did not parse for me. Apparently, there is an error somewhere around this line:

Syntax error, unexpected T_STRING, expecting T_FUNCTION or T_CONST

    /**
     * Aspect loader instance
     */
    protected AspectLoader $loader;

    /**

    {
        $this->container = $container;
        $this->loader    = $loader;
    }

    /**

        if ($this->container->has($name)) {
            $advisor = $this->container->get($name);
        } else {
            list(, $advisorName) = explode('.', $name);
            list($aspect)        = explode('->', $advisorName);

            $this->loader->loadAndRegister($aspectInstance);

            $advisor = $this->container->get($name);
        }

        if (!$advisor instanceof Advisor) {
            throw new InvalidArgumentException("Reference {$name} is not an advisor");
        }
        $this->$name = $advisor->getAdvice();

        return $this->$name;
