As PHP grew, it began to be recognized as a world-wide
popular development platform. One of the most interesting
ways of seeing this trend was by observing the books about
PHP that came out throughout the years.
While these books were the first of their kind - they
were followed by a large number of books from a host of
authors and publishers. There are over 40 books in English,
50 books in German, and over 20 books in French! In addition,
you can find books about PHP in many other languages,
including Spanish, Korean, Japanese and Hebrew.
