ZipArchive::locateName
If you try this to open a file with creation in mind (= empty zip to fill with other files), this may not work :
$res = $zip->open($zip_file, ZipArchive::CREATE);
// you may get false
Try this instead, it should work :
$res = $zip->open($zip_file, ZIPARCHIVE::OVERWRITE);
ZipArchive::open

It seems the filename has to end in '.zip', so this suffix must be added when using tempnam() to create a random temporary file name.

If the directory you are writing or saving into does not have the correct permissions set, you won't get any error messages and it will look like everything worked fine... except it won't have changed!
Instead make sure you collect the return value of ZipArchive::close(). If it is false... it didn't work.
