The meta stuff
I'll be writing a series of posts exploring DIY drupal hosting options. Many agencies and freelancers need a workflow to manage and maintain their Drupal sites on a budget. Of course, they incur the cost of maintiaining and deploying the system(at least initially) and the additional learning curve involved in using the system, but they get the following advantages:
Ever wondered what exists inside the vendor/ directory of your Drupal or PHP codebase? Let's dive down the rabbit hole and see.
A little bit of history
Let's digress into a little history lesson to see why things are they way they are in the PHP autoloading world.
