An experienced programmer who does not know PHP 5 should be able to use this book to get up to speed within a few days. Holzner presents a concise and logical unfolding of PHP, and without taking 1000 pages to do so. The first 4 chapters are about using the basic syntax. Much the same as several other languages like C or C++. The if-else and switch statements will look similar to what you're already used to, for example. There are the open and closing notations for a code block to get used to. But this is pretty simple. The real point to the language is given in later chapters, on handling HTML in web pages and making forms and being able to validate these. Here, you really need prior acquaintance with web servers and HTML, to fully appreciate what Holzner explains about PHP. He also gives more advanced usages. Where PHP can be written in an object oriented manner. A relatively recent thing in PHP. Also, he shows how to hook up PHP to a back end relational database. For the latter, he chooses MySQL. But Postgresql or any other RDB could probably also do just as well.
