I have seen some sites that teach PHP and was completely lost. All I know is html. The sites I have tried to learn it on used terms I was not familiar with. It was overwhelming. I am not dumb, but is there a good learning site that does not talk over my head or beyond my experience as if assuming I am already very familiar with programming terms?
I have installed ready made PHP sites on hosting accounts and there was always a file called the handler or something and right now I am looking at PHP site files where there is no such file. I need some well written easy to understand instructions and lessons.
The php manual [php.net] is actually quite well written, once you get the hang of what to look for. The user comments under each function usually give you a good starting point if you are not quite sure what you are doing with the function.
There are a lot of sites that offer very good tutorials on the web...just cant list them as they dont fit with the forum charter. So to get those site you can google for the topic you are looking for i.e. if you want to learn about includes so that you dont need to manually put your navigation on every page of your site, google for 'php includes', you will soon find 2 or 3 sites cropping up in the top 10 for most searches you do.
Or try googling 'php tutorial'.
Also have a look through posts here, as there is a lot of code getting posted. I find when trying to learn a new language that it is a lot easier if you can look at other code then try to pull it apart and learn what it does. The other thing to do is dont use pre-made code. Pull it apart and rewrite it, even if you go back to the original at the end. As this will get you looking through the manual, asking questions and getting a better hang of the language. That may not be possible if you have time constraints, however it will help you to understand the code.
