Container.php Here some part of code


 protected function resolveClass(ReflectionParameter $parameter)
    {
        try {
            return $this->make($parameter->getClass()->name);
        }

        // If we can not resolve the class instance, we will check to see if the value
        // is optional, and if it is we will return the optional parameter value as
        // the value of the dependency, similarly to how we do this with scalars.
        catch (BindingResolutionException $e) {
            if ($parameter->isOptional()) {
                return $parameter->getDefaultValue();
            }

            throw $e;
        }
    }

    You can replace it with getType(), which the documentation suggest. You have to create your own ReflectionClass, from the ReflectionType. This should do the trick.

    $reflectionClass = new ReflectionClass($reflectionParam->getType()->getName());

    I have this sandbox, that helped me assure it was working as intended.

    Laravel 5.4 seems to have incorrect platform requirements. Specifically that it requires PHP version >= 5.6 however it has code that will not work in PHP 8. Since 5.4 is end of life I would not expect any official code changes to make it work for PHP 8 so you would either need to fork and maintain your own Laravel 5.4 branch that solves these problems or upgrade your Laravel version to one that supports PHP 8.

    The first Laravel version that supports PHP 8 is Laravel 6

    because ReflectionParameter::getClass() is deprecated in php 8 .

    solution go to

    vendorlaravelframeworksrcIlluminateContainerContainer.php

    and go to

    protected function resolvePrimitive(ReflectionParameter $parameter)

    and replace

    $parameter->getClass()** with **$parameter->getType()->getName() .

    You might need to update your global composer.json with:

    composer global update

    I had some annoying issue so I hade to run:

    composer global update --ignore-platform-reqs
