Fatal error: Uncaught Error: Function name must be a string in C:\xampp\htdocs\em0126\app\code\core\Mage\Core\Model\Layout.php:555 Stack trace: #0

Question

I am facing these errors while accessing Magento folder from XAMPP (localhost/magento):

Fatal error: Uncaught Error: Function name must be a string in C

Answer 1

Changed the line 555 to:

$out .= $this->getBlock($callback[0])->{$callback[1]}();

It works. But one thing I'm not sure of if this is really a php7. I'm running this on my website with same files and configurations on the same server and it's working with no issues without changing that line.
