Shared with PHPOffice

[Progi1984]

Some parts of PHPOffice projects are recurrents :

• graphs in OpenXML
  • https://github.com/PHPOffice/PHPExcel/blob/develop/Classes/PHPExcel/Writer/Excel2007/Chart.php#L125
  • https://github.com/PHPOffice/PHPWord/blob/master/src/PhpWord/Writer/Word2007/Part/Chart.php
  • https://github.com/PHPOffice/PHPPowerPoint/blob/master/src/PhpPowerpoint/Writer/PowerPoint2007/Chart.php#L374
• convert between drawing units :
  • https://github.com/PHPOffice/PHPExcel/blob/develop/Classes/PHPExcel/Shared/Drawing.php#L38
  • https://github.com/PHPOffice/PHPWord/blob/master/src/PhpWord/Shared/Drawing.php#L17
  • https://github.com/PHPOffice/PHPPowerPoint/blob/master/src/PhpPowerpoint/Shared/Drawing.php#L27
• and so on...

The idea would be to create a package (PHPOfficeShared or PHPOffice or...) which permits to group useful functions in one place for improving all projects.

Poke teams :

• @PHPOffice/phpexcel-team
• @PHPOffice/phppowerpoint-team
• @PHPOffice/phpword-team

Would also apply to components like the OLE Reader/Writer, and also to some document-level elements like DocumentProperties and parts of DocumentSecurity

[MarkBaker]

Useful in a separate repository when dependencies can be managed via composer, but harder for doing a non-composer build of all components

[Progi1984]

@MarkBaker Exactly for OLE and DocumentProperties.

Ah ! Composer save our lives :p
May be the solution will be an autoload (not in the case where we use Composer) for loading PHPExcel & PhpOfficeShared ?

[MarkBaker]

Namespacing would be a godsend there, but that requires forcing the minimum version requirement to PHP 5.3.0.... which is all to the good as well, as it means guaranteed SPL in PHP core, closures, etc

[Progi1984]

@MarkBaker Actually, the minimal support is :

• 5.2.0 for PHPExcel
• 5.3.0 for PHPPowerPoint
• 5.3.3 for PHPWord

+1 for separate subproject in PHPOffice family managed by Composer. So we can have other projects depended on it. I would call it Common (\PhpOffice\Common). Shared is not a good name, because this term is used in OOXML (there are so called shared objects). So, to avoid confusion, we should choose a different name.

As regards PHP version, I suggest starting with at least 5.3. PHPExcel will use the lib when got PHP upgraded.

@RomanSyroeshko Good idea for Common ;)
I agree with you for PHPExcel.

Done with https://packagist.org/packages/phpoffice/common
