Zend Framework: Zend_Io Component Proposal

Table of Contents

1. Overview

Zend_Io is a package providing means to read/write primitive PHP types (string, integers, ...) to a character stream.

2. References

• PHP Reader Project

3. Component Requirements, Constraints, and Acceptance Criteria

• This component will read primitive PHP types from character streams.
• This component will write primitive PHP types into character streams.

Please note It's possible to use regular PHP file functions to carry out operations on the same resource while it is used by Zend_Io_Reader.

4. Dependencies on Other Framework Components

• Zend_Exception

5. Theory of Operation

6. Milestones / Tasks

• Milestone 1: Working prototype transformed from existing code and checked into the incubator (necessary tasks: conform to Zend naming conventions, and refactor to support the new API described here).
• Milestone 2: Unit tests exist, work, and are checked into SVN.
• Milestone 3: Initial documentation exists.
• Milestone 4: Moved to core.

7. Class Index

• Zend_Io_Reader
• Zend_Io_FileReader
• Zend_Io_StringReader

• Zend_Io_Writer
• Zend_Io_FileWriter
• Zend_Io_StringWriter

• Zend_Io_Exception
