如何在Laravel 5.6中更新Braintree付款依赖关系？

Question

I am working with Laravel 5.6 and using Braintree payment gateway sand box. but when I update my php version it is encounters some error. like this

Function create_function() is deprecated
in Util.php line 206
at HandleExceptions->handleError(8192, 'Function create_function() is deprecated', 'C:\\Users\\mala\\Desktop\\ddddd\\vendor\\braintree\\braintree_php\\lib\\Braintree\\Util.php', 206, array('string' => 'client_token', 'delimiter' => '-', 'callbacks' => array()))in Util.php line 206 

so, I am using braintree vertion, ``` "oureastudios/laravel5-braintree": "dev-master" `` but when I search in internet most people suggested update braintree dependancy to v3.26.0. then My problem is how can I update My current braintree to above new vertion?

Answer 1

create_function is deprecated in PHP 7.2

in the file /Braintree/Util.php the function delimiterToCamelCase

Use:

$callback = function ($matches) {
                return strtoupper($matches[1]);
            };

instead of:

$callback = create_function('$matches', 'return strtoupper($matches[1]);');
