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.
