Programming PHP 2nd Edition
Programming PHP, 2nd Edition, is the authoritative guide to
PHP 5 and is filled with the unique knowledge of the creator
of PHP (Rasmus Lerdorf) and other PHP experts. When it comes
to creating websites, the PHP scripting language is truly a
red-hot property. In fact, PHP is currently used on more
than 19 million websites,
surpassing Microsoft's ASP .NET
technology in popularity. Programmers love its flexibility
and speed; designers love its accessibility and convenience.
As the industry standard book on PHP, all of the essentials
are covered in a clear and concise manner. Language syntax
and programming techniques are coupled with numerous
examples that illustrate both correct usage and common
idioms. With style tips and practical programming advice,
this book will help you become not just a PHP programmer,
but a good PHP programmer. Programming PHP, Second Edition
covers everything you need to know to create effective web
applications with PHP. Contents include:
Detailed information on the basics of the PHP language,
including data types, variables, operators, and flow control
statements
Chapters outlining the basics of functions, strings, arrays,
and objects
Coverage of common PHP web application techniques, such as
form processing and validation, session tracking, and
cookies
Material on interacting with relational databases, such as
MySQL and Oracle, using the database-independent PEAR DB
library and the new PDO Library
Chapters that show you how to generate dynamic images,
create PDF files, and parse XML files with PHP
Advanced topics, such as creating secure scripts, error
handling, performance tuning, and writing your own C
language extensions to PHP
A handy quick reference to all the core functions in PHP and
all the standard extensions that ship with PHP
Praise for the first edition:
"If you are just getting into the dynamic Web development
world or you
are considering migrating from another dynamic web product
to PHP, Programming PHP is the book of choice to get you up,
running, and productive in a short time."
--Peter MacIntrye, eWeek
"I think this is a great book for programmers who want to
start developing dynamic websites with PHP. It gives a
detailed overview of PHP, lots of valuable tips, and a good
sense of PHP's strengths."
--David Dooling, Slashdot.org
