No. But programming is not platform dependant. As a matter of fact, Macs are better suited to most tutorials than PCs because of OSX's Unix backend.
You want to learn PHP through PHP tutorials, NOT through Dreamweaver tutorials. Look at the sites I've linked. Start off using a text editor, honestly. Get to know the language. www.php.net should be in a quick link.
You're trying to jump a gap. Dreamweaver isn't kiddy proof, it still does require some general knowledge to get it working. If you need a functional site quickly, I'd recommend looking into some CMS's -- Content Management Systems. Or you can go on the next looking for scripts others have written to install on your site.
It's really a choice between two routes:
- Take the time to learn how PHP works.
- Or install prebuilt scripts onto your site.
Take your pick.
