We have a web application running on a shared hosting account that was built using Laravel. We now need to implement a payment gateway that requires vendor packages for the SDKs. However as mentioned composer is not supporting at all with the current hosting company. 

Steps we took to get Laravel up and running on shared host:

* We developed the application locally first on a development machine
* Added version control and pushed the files to GitHub
* We used SSH to gain access and then did a `git pull` to the server

We unfortunately had to package the vendor folder separately and push that over to the server (as this is not highly recommended without composer) it was our only option at the time. 

By some miracle we got the application to run without any issues. 

The problem we face now, is that we need to install SDK packages through composer for the payment gateway we need to implement.

We did the initial setup and build of the new module on the development machine first, but the problem we now face is, simply pushing the SDK into the vendor folder does not work, it still moans about the class files not being found. and there is no way for me to do a `composer dump-autoload -o`

We even went as far as re-packaging the updated version of the vendor folder, deleting the current one on the application and then doing another pull down from GitHub, but that throws all sorts of `bootstrap/app.php` issues with classes not being found.

We did try force `allow_url_fopen=1` with a manually downloaded version of composer, but the shared hosting PHP CLI is 5.6 and PHP 7.0 is required.

We are unfortunately stuck and any advice would be highly appreciated.
