Whereas in some programming languages it doesn't matter if you use single or double quotes, it matters highly in C++ (and some others, such as Java, also).

Laravel run app on different port

Just because I keep forgetting this command -

if you wish to open your Laravel application not on the standard 8000 port but on a different one, use this:
