The book is split into three the extensions, the case studies, and the function reference — that way someone looking to just read case studies has a definite place to start, and people looking for the descriptions without large amounts of code can read the beginning and the one's who want to stick it by their side for reference, know exactly where to go.Author Devon Dell has been designing Internet applications from the time he grappled with writing Perl CGI sripts in 1996.He has since expanded to using PHP,C,Java,Tcl for Internet applications.
