    What's the difference between cascade="remove" and orphanRemoval=true in Doctrine 2

TLDR: The cascade={"remove"} is like a "software" onDelete="CASCADE", and will remove objects from the database only when an explicit call to $em->remove() occurs. Thus, it could result in more than one object being deleted. orphanRemoval can remove objects from the database even if there was no explicit call to ->remove().
I answered this question a few times to different people so I will try to sum things up in this Gist.
Let's take two entities A and B as an example. I will use a OneToOne relationship in this example but it works exactly the same with OneToMany relationships.

                Using GNU command line tools in macOS instead of FreeBSD tools
              
          
    macOS is a Unix, and not built on Linux.

I think most of us realize that macOS isn't a Linux OS, but what that also means is that instead of shipping with the GNU flavor of command line tools, it ships with the FreeBSD flavor. As such, writing shell scripts which can work across both platforms can sometimes be challenging.
Homebrew

Homebrew can be used to install the GNU versions of tools onto your Mac, but they are all prefixed with "g" by default.

All commands have been installed with the prefix "g". If you need to use these commands with their normal names, you can add a "gnubin" directory to your PATH from your bashrc.
