This is a really good book on PHP to veteran software engineers ever since I read its sample pages published here from my Kindle last night.
I haven't purchased the book yet but I am pretty much sure that I will. The author's approach towards the subject touches basics of the computer science - how to do things better. To those new to PHP like me, the language itself seems relatively "primitive" in perspective of pre-defined modularity compared with the other programming languages, for example, HTTP Post and Get in pre-defined event handling routines in ASP.NET with C# from Microsoft; PHP is "primitive" because it does not have pre-defined routines, somehow, similar to the early ANSI/ISO C, or C++; but thus, it does leave vast space for the programmers to control his or her own routines in software engineering by their own creativities.
The book talks about PHP from "basics," and it is necessary for me to learn the language more efficiently. For example, how different syntaxes for the same results would be interpreted by the compiler - a string value rounded with double quotes will be treated differently from single quotes by the compiler; Similar concerns if you are a veteran software engineer, the book gives your clarifications!
I will definitely purchase the book and try to update my review later on. For the time being, I give 5-stars.
