This may be a fantastic deal for some. For me, the most important tools for a web application developer consist of a text editor that does decent syntax highlighting, jslint for finding flaws in my JavaScript, a good solid understanding of the PDO class for PHP, and a good solid understanding of the DOMDocument class for PHP. Those last two can really only be learned by doing.
You must learn the proper way to securely interact with a database (that’s where PDO is essential) and you must have a good understanding of the power of the Document Object Model if you are going to create solid secure web applications.
In my humble opinion.
