How to save cells in excel file in Php ZipArchive?

Question

PHP

What method can be used to resave cells after data entry? I use a template that is on the server, it has special tags for adding data. Process: opened file (using

$array_path = array('xl/sharedStrings.xml', 'xl/worksheets/sheet1.xml', 'xl/worksheets/sheet2.xml', 'xl/worksheets/sheet3.xml');

), added data, closed it, saved it on the local computer. I can't find it in the documentation. Can be header any prescribe special?
And this is necessary so that in each cell there is a formula that in Excel itself already works with data (conditions, recalculation), etc.
