Please look at the date a tutorial was written before deciding whether it is useful. Some tutorials, especially relating to plugins, can get obsolete quite fast. The one you're referring to was made five years ago. Five years! I think that one was written with R6 and we're currently almost at R40.
Save yourself the trouble and do not learn outdated methods. Start with the latest and go on from there. You may take a look at AndreT's tutorial (https://sampforum.blast.hk/showthread.php?tid=337810) instead. This one is slighly outdated - although far less than the one you referred to - and you use mysql_tquery instead of mysql_function_query. But the logic mostly still applies.
