I'm fully aware of these facts. The one I use for this specific solution is
O'Reilly's Webdatabase applications with PHP and MySQL.
In fact, I don't actually read the book and try out the examples, I just got
their code, analyzed it and modify it - I go by "Learning by doing". Not
the perfect way, but my way.
Alongside this, I read at
www.php.net and
www.mysql.com to get info as much
as possible.
Books are for me a way to start of, but only by doing I learn.
Books have sometimes valuable information about doing things in a better
way. Doesn't mean the code is perfected, but it might often be better then
whats in my mind. That's a learning process for me.
I have learned in time, that O'Reillys books are brilliant and thats the
reason for me to prefer them to start with.
There is always a development going on but If you always want up-to-date
stuff, you never buy a book, you never buy a computer, you never buy a car.
At some point you have to take a decision and go from there. That's what I
do here.
I've learned for the past 20 years, I'm still going strong.
I never reject input nor ideas. Why should I ?
