So I use php.net for the documentation, but I was looking for some good php articles to brush up on the latest best practices and security concerns. Or some articles on something practical, like how to create some working example. I'm about to do a site in php and I just wanted some more info on php.
google "PHP Tutorial"
documentation/reference is when you already started and you want to refer / look up when you forget something or get stuck.
Book is the best way to go.
I just found a lot of links for PHP reading in this Frihost forum topic.
Frihost Forum Index -> Miscellaneous -> Tutorials -> PHP Tutorials
I mean what are some more specific articles for tips for an experienced person who wants to be more efficient/secure/etc?
Does that make sense?
Actually there a lot of php tutorials out there just do some searching it would be better if you hare on a tight budget. Now, download the php manual from php.net and open it everytime you start to code it's a good reference to see a lot functions and examples.
