This problem is that ZipStream, in contrast to ZipArchive, is saving 2 files with the same path. I have opened an issue with ZipStream, who agree that this appears to be a bug. For the case in question, PhpSpreadsheet is attempting to save a file with the same path twice (and unexpectedly succeeding) because of a clone operation. This fix attempts to rectify the problem by keeping track of all the paths being saved in the zip file, and not attempting to save any duplicate paths. The problem case attempted to save printersettings1.bin twice, but there are other possible exposures, e.g. by cloning a sheet with a drawing.The new test cases clone an existing sample which has both printer settings and drawings. |

PHPExcel vs PhpSpreadsheet ?
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet master branch.
Do you need to migrate? There is an automated tool for that.
