To continue programming effective and stress-free, cutting-edge practices and rules are crucial. Object-oriented programming and layout support deal with complexity by means of protecting parts cleanly separated. Unit checking out is helping hinder never-ending, arduous debugging periods. Refactoring retains code supple and readable. Hypertext Preprocessor deals all this-and extra.

PHP in Action exhibits you the way to use personal home page suggestions and rules to the entire most typical demanding situations of internet programming, including:

  • Web presentation and templates
  • User interplay together with the Model-View-Contoller structure
  • Input validation and shape dealing with
  • Database connection and querying and abstraction
  • Object persistence

buy of the print booklet comes with a proposal of a unfastened PDF, ePub, and Kindle publication from Manning. additionally to be had is all code from the publication.

C HA PT E R 1 PHP AND MODERN SOFTWARE DEVELOPMENT If you choose to hack, you can typically get a lot of features done quickly in the beginning, but as your application grows in complexity, you will be slowed down by hard-to-find bugs and the need to maintain duplicated code. The traditional alternative is typically to emphasize up-front design. The idea is that you need to plan well ahead and design everything in a relatively detailed manner before you start to code. And if you’re good at doing the design, the resemblance between what you do and what the customer needs will be sufficient to get you through to the first release without major problems.

If you turn the diagram 90 degrees counterclockwise, it will be oriented to match the building analogy: The message flow climbs the stairs, passing the floors one by one, jumps out of the window on the PDO floor, and is caught in the net set up at the ground floor—the application. There is one important advantage that exceptions share with die(): they interrupt further processing. The reason this is useful is that typically, when an exception is thrown, the rest of what happens in the current method is meaningless.

LANGUAGES, PRINCIPLES, AND PATTERNS 13 particular purpose may be a time-consuming task. This book will focus mostly on the patterns that are most relevant to web programming and to the web programmer’s everyday tasks. The interest in design patterns has started to become serious in the PHP community only in the last few years. PHP developers haven’t had much of a culture for this kind of thing, but nowadays you can easily find examples of design patterns in PHP. 5 14 Refactoring Refactoring means improving the design of existing code.
