Bugfix: Linux not identifying .xlsx as correct mimetype...

[AzzaAzza69]

In order to differentiate from regular .zip files, the mimetype looks for files added to the .xlsx in order (as per Office 2007+), in particular: [Content_Types].xml needs to be first followed by at least one file in the xl/ folder...

Can you tweak the saveToFile function?

PS. It may be more prudent to move the exception for "No worksheets defined" BEFORE the file_exists/unlink check as no worksheets will result in the file being deleted without creating any output! <Maybe even just before the $zip->close() in case any other problems/exceptions cause the .zip not to be created?>

Thanx for the link, I'll explore this pronlem

The order of writing entries to the XLSX-file has been changed in v.4.7 And mimetype must be correct now
