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

Your solution

Fatal error: Uncaught Error: Function name must be a string in ... app\code\core\Mage\Core\Model\Layout.php:555 ...

This error was easy to fix because the problem was in the following line:

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

Instead it should be:

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

Answer 2

Go to app\code\core\Mage\Core\Model\Layout.php line no 555 and

 change $callback[1] to {$callback[1]}

Answer 3

Its due to PHP7

It's not recommended to edit the core file. We will override it.

Copy this file app/code/core/Mage/Core/Model/Layout.php into app/code/local/Mage/Core/Model/Layout.php

Change code in app/code/local/Mage/Core/Model/Layout.php file (line # 555)

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

To:

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

Answer 4

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.

Answer 5

it is a php7 issue since when i upgraded from 5.6 to 7.0 i got this error. to fixe it i edited core file (hope a patch will come soon) either like mentionned in other ansewers before or like below:

Go to app\code\core\Mage\Core\Model\Layout.php line no 555

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