3. Component Requirements, Constraints, and Acceptance Criteria

  • This component will not read/write/convert old formats like .xls, .doc, .ppt, ...
  • This component will read/write ISO/IEC 29500 Office Open XML File Formats
  • This component will use Zend\Cache for caching readed files
  • This component will use Zend\Translate and/or Zend\Locale for translation
  • This component maybe will support both "ISO/IEC 29500" and "ECMA-376"

4. Dependencies on Other Framework Components

  • Zend\Exception
  • Zend\Cache
  • Zend\Translate
  • Zend\Locale
  • Zend\Config (maybe)

5. Theory of Operation

General for using this component, the ZipArchive and XML Manipulating from PHP is needed.

UC-01 write

1. User defines what shall be written to the output (texts, images, meta-data, formatting, ...)
2. Forwarding the provided data to the generation classes
3. Generate and write each single XML document
4. Putting it in the ZIP together

UC-01 open/read

1. Unzip the XMLs
2. open [Content_Types].xml and _rels/.rels (these two files are required minimal)
3. Looping through the needed files (from user)
4. Return output

6. Milestones / Tasks

  • Milestone 1: Reading/Understanding the whole XML parts which are possible in the ZIP of word, excel, powerpoint
  • Milestone 2: Concept
  • Milestone 3: Class/Folder structure
  • Milestone 4: Working prototype
  • Milestone 5: Feedback
  • Milestone 6: Writing Tests
  • Milestone 7: Final coding
  • Milestone 8: Documentation / Review

7. Class Index

  • Zend\OfficeOpen\Exception
  • ....

8. Use Cases

UC-01 write

use Zend\Excel;
$excel = new Excel(...);

$worksheet = $excel->getWorksheet(...);

$style1 = new Excel\Style();

$cell = new Excel\Cell();

$worksheet->setCell('A', '1', $cell);
