eZ components 2007.2.1 is a useful program including independent building blocks for PHP application development eZ components for speeding up development and limiting risks. An application can use one or more components effortlessly as they all adhere to the same naming conventions and follow the same structure.

All components are based on PHP 5.1, except for the ones that require the new Unicode support that will be available from PHP 6 on.

The Base component provides basic functionality that all other components rely on. This basic functionality contains a certain set of exceptions and a mechanism to load components on demand, reducing memory usage. Other components build around this Base component and provide functionality for a whole range of different subjects.

Subjects include reading archive files (.zip, .tar), caching data, database SQL abstraction layer and schema management, debugging and event logging, image analysis and manipulation, in-process communication, sending fully feature mail message, templating and the safe usage of input data. Besides these main features there are also a few other components dealing with a whole range of subjects.

This is a complete list of all the individual libraries that is included in eZ components.

• Archive
• • Allows you to extract and create archive files, such as .tar (ustar, v7tar and gnutar) and .zip
• Cache
• • A solution for caching, supporting multiple backends allowing you to specify the best performing solution for your caching-problem.
• Configuration
• • A component that allows you to use configuration files in different formats.
  • The formats include the standard .ini file, and an array based format.
• ConsoleTools
• • A set of classes to do different actions with the console (also called shell). It can render a progress bar, tables and a status bar and contains a class for parsing command line options.
• Database
• • A lightweight database layer on to of PHPs PDO that allows you to utilize a database without having to take care of differences in SQL dialects.
• DatabaseSchema
• • A set of classes that allow you to extract information from a database schema, compare database schemas and apply a set of changes to a database schema.
    
• Debug
• • This components provides a set of classes that help you to debug an application. It provides timers and report generators for different formats that give a summary of warnings and errors that occurred within your application.
• EventLog
• • Allows you to log events into files or other storage spaces in different formats.
• Execution
• • Provides functionality to give feedback to your applications users when a fatal error happened or an uncaught exception was thrown.
• Feed
• • Provides reading and writing support of RSS (multiple versions) and ATOM feeds.
    
• File
• • Provides support for file operations which are not covered by PHP or are just missing.
    
• ImageAnalysis
• • This class allows you to analyse image files in different ways. At least the MIME type of the file is returned. In some cases (JPEG, TIFF and GIF) additional information is gathered as well.
• ImageConversion
• • A set of classes to apply different filters on images, such as colour changes, resizing and special effects.
• Mail
• • The components allows you construct Mail messages conforming to the RFCs. It has support for attachments, multipart messages and HTML mail. It also interfaces with SMTP to send the e-mail. Reading and parsing mail messages comes in version 1.1.
• PersistentObject
• • This component allows you to store an arbitrary data structures to a fixed database table. The component provides all the functionality needed to fetch, list, delete etc these datastructures.
• PhpGenerator
• • Provides a simple interface for creating PHP files and executing PHP code.
• SystemInformation
• • Provides access to common system variables, such as CPU type and speed, and the available amount of memory.
    
• Template
• • A fully functional Templating system, supporting template compilation in different levels, user defined functions and operators, an optimizer, output escaping for different output handlers to prevent XSS and other security problems and a plug in system for extra functionality (such as a Translation system).
    
• Translation
• • A component that reads XML translation definitions (the Qt Linguist format), supports caching of translation contexts and presents you with a class to apply translations to strings. A filter system allows you to transform translation definitions for special use.
• Url
• • Provides functionality for parsing URL parameters, and path manipulation.
• UserInput
• • A component that assists you to safely user input variables coming into your application. It builds on top of PHPs filter extension and extends it by providing a more inituitive API.
