Brandon Savage has written a sort of letter to those developers new to the PHP community and to the language to encourage them to not worry, that things will come in time.
Every day, new people join the PHP world, writing their first "hello world" script and moving on from there to connect to databases, build CRUDs, and otherwise explore the PHP language. If you're one of them, you shouldn't feel inadequate. No, learning PHP is a learning process. One of PHP's strengths is that it is easy to learn, and that anyone can learn how to do it. Fewer can learn how to do it properly, but for those that do learn how to do it right, it can be a powerful language and a solid tool.
