If you work with Laravel or PHP and you may encounter the below error
"error": "Array callback must have exactly two elements" laravel
Well,there could be many reasons for this error. But from the error reporting we get that "A callback function was expecting two elements, but one or none was given to this callback function".
Here you see I am using $_SERVER directive on line 20. And I am passing HTTP_STRIPE_SIGNATURE. It's part of our PHP Stripe payment.
In this case $_SERVER is being called like a method because I used () with $_SERVER(). But it should be [], which means $_SERVER[] takes array like value.
After I changed $_SERVER() to $_SERVER[] the error "PHP Error :Array callback must have exactly two elements Laravel" is gone.
