Being highly flexible in building dynamic, database-driven web applications makes the PHP programming language one of the most popular web development tools in use today. It also works beautifully with other open source tools, such as the MySQL database and the Apache web server. However, as more web sites are developed in PHP, they become targets for malicious attackers, and developers need to prepare for the attacks. Security is an issue that demands attention, given the growing frequency of attacks on web sites. Essential PHP Security explains the most common types of attacks and how to write code that isn't susceptible to them. By examining specific attacks and the techniques used to protect against them, you will have a deeper understanding and appreciation of the safeguards you are about to learn in this book. In the much-needed (and highly-requested) Essential PHP Security, each chapter covers an aspect of a web application (such as form processing, database programming, session management, and authentication). Chapters describe potential attacks with examples and then explain techniques to help you prevent those attacks. Topics covered include: Preventing cross-site scripting (XSS) vulnerabilities Protecting against SQL injection attacks Complicating session hijacking attempts You are in good hands with author Chris Shiflett, an internationally-recognized expert in the field of PHP security. Shiflett is also the founder and President of Brain Bulb, a PHP consultancy that offers a variety of services to clients around the world.
"PHP Web Application Security" helps readers build secure Web applications, using Apache and MySQL along with PHP 5. The book details the attacks that hackers use against Web sites, and shows how to correctly configure Apache and PHP to guard against them.
* PHP is the leading programming language for developing dynamic web applications. The simplicity of PHP, the ease of development, a large community, and the expansive repository of open source PHP libraries, make it a favorite of web designers and developers. * Describes many useful and popular packages for PHP; Explains how to maintain your own local package repository * Provides lots of examples of how to use little- or poorly-documented PHP packages.
To keep programming productive and enjoyable, state-of-the-art practices andprinciples are essential. Object-oriented programming and design help managecomplexity by keeping components cleanly separated. Unit testing helps preventendless, exhausting debugging sessions. Refactoring keeps code supple andreadable. PHP offers all this-and more. PHP in Action shows you how to apply PHP techniques and principles to all themost common challenges of web programming, including: Web presentation and templates User interaction including the Model-View-Contoller architecture Input validation and form handling Database connection and querying and abstraction Object persistence Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.
PHP is experiencing a renaissance, though it may be difficult to tell with all of the outdated PHP tutorials online. With this practical guide, you’ll learn how PHP has become a full-featured, mature language with object-orientation, namespaces, and a growing collection of reusable component libraries. Author Josh Lockhart—creator of PHP The Right Way, a popular initiative to encourage PHP best practices—reveals these new language features in action. You’ll learn best practices for application architecture and planning, databases, security, testing, debugging, and deployment. If you have a basic understanding of PHP and want to bolster your skills, this is your book. Learn modern PHP features, such as namespaces, traits, generators, and closures Discover how to find, use, and create PHP components Follow best practices for application security, working with databases, errors and exceptions, and more Learn tools and techniques for deploying, tuning, testing, and profiling your PHP applications Explore Facebook’s HVVM and Hack language implementations—and how they affect modern PHP Build a local development environment that closely matches your production server
The purpose of this book is bring the power and ease of use of PHP to anyone with a desire to learn PHP. It starts by covering the history of PHP before providing a high level overview of how PHP works and why it is so useful to web developers. It then moves on to cover each area of PHP in detail, from the basics of the scripting language through to object oriented programming, file and file system handling and MySQL and SQLite database integration. In addition, chapters are also provided covering the creation and handling of HTML based forms and maintaining state using both cookies and PHP sessions. Each topic area is accompanied by extensive real world examples intended to bring theory to life.
A pocket guide jam-packed with immediately useful and essential code phrases for the PHP developer's everyday use.
A Web-Based Introduction to Programming is designed for use in introductory programming, programming logic and design, or Web programming courses, and for anyone seeking a painless way to learn the basics of programming by developing small Web applications. The book is clearly written, using consistent examples in every chapter and step-by-step descriptions of standard programming procedures. Each chapter follows precise learning outcomes that are accurately tested by the end-of-chapter quizzes and exercises. A Web-Based Introduction to Programming keeps the focus on the need for beginning programmers to learn essential syntax and control structures with minimal complexity. Each chapter focuses on a single topic and related material is provided in appendices. Students learn to convert requirements into algorithms, and then develop small Web-based applications using a combination of PHP and HTML. The chapter code exercises are designed to skill and confidence step-by-step: Fixit exercises provide small programs that include a single error of some kind and help students develop their problem-solving abilities and debugging skills. Modify exercises provide working programs that must be modified to perform a somewhat different or additional function. These exercises test student's ability to read, understand, and adapt existing code. Code completion exercises allow students to apply all concepts and tools covered in the chapter by developing new applications. All required software is provided and can be installed quickly and easily in minutes under Windows, Macintosh OS X or Linux. The software can be installed entirely on a USB drive so that students can carry their entire work environment with them (no need for special classroom installation). Significant changes to the second edition include: the latest version of the standalone Web server; even more code examples; additional code exercises for each chapter; flow chart examples to help explain control structures; more in-depth coverage of associative arrays and Web sessions; more extensive discussion of include files; additional references to emerging technologies. The Web site www.mikeokane.com/textbooks/WebTech/ includes all materials found on the CD, and also provides access to additional exercises, test banks, slide presentations, quiz solutions, code solutions, and other instructional resources. "This is the best logic book I have ever had in over 25 years of teaching!" -- Bob Husson, Craven Community College "I teach intro to programming and algorithms and I have used this book for three terms. It is excellent. The book's content leads students through the examples in a natural way that makes learning traditional programming concepts easy and students retain the concepts. The coding exercises build upon each other from algorithms all the way through small PHP programs. As a teacher I highly recommend this book for students and instructors alike." --Charlie Wallin, Asheville-Buncombe Technical Community College "The textbook, A Web-Base Introduction to Programming, was my first exposure to PHP. I could not have asked for a better introduction. The explanations, examples, and order of topics covered, made teaching and learning the basics of PHP a simple process. My students found the exercises and assignments at the end of each chapter fun but challenging. My only regret is that I did not discover this book sooner." -- Joe Sherrill, Martin Community College (retired)
The accompanying CD-ROM contains all source code from the book, including three complete applications.
