I'm not sure if I'm understanding these two functions right in PHP can someone explain it to me? I think json_encode makes sure that php can read the .json file but you have to specify a variable name, whereas with json_decode it's the same but you have to specify a file name. I might be wrong.

json_encode converts PHP values/objects/arrays into JSON objects/strings
json_decode converts JSON objects/strings into PHP values/objects/arrays
It gets used a lot in scenarios where you are sending HTTP request and response data (in AJAX operations, for example).
It is something you should experiment with to really understand.
Go back and forth and examine your output (especially when you log data to the console).
