What does the Contents string mean in the Put method of the Storage object?

Question

Laravel

I see this in the manual:

Storage::disk('local')->put('file.txt', 'Contents');

What does 'Contents' mean in a method? Why is it indicated?

Answer 1

Storage is a facade for Filesystem, in Filesystem the put method is described like this , it turns out that this is a wrapper for file_put_contents, $contents is just data that needs to be written to a file)
