There's your problem, if you can't be bothered learning new stuff then:
But, I know always get hints that I have to use MySQLi or PDO and I honestly know nothing about it and I don't feel like learning a lot of new stuff, but still wants to work with php and MySQL. All web stuff I've been doing for years now is done with Dreamweaver.
You already said you don't really want to learn too much so all of the advise on here will be to scrap a WYSIWYG and go for full on coding manually in HTML/CSS/MySQL - PDO/SQLi so why bother? I can almost guess you're not even designing responsive websites. I just hope you're only working on personal websites and not designing/developing for clients.
So, is there any other great alternative to use instead of Dreamweaver?
But, still doing it simple without too much hand coding?
