When you use ziparchive to zip a folder with
subfolders and files on a windows server it creates the file, however
decompression on a Linux server the files are all wrong,
from what I was able to discover is due to the position of the bar that it does
for windows example:

the folder on windows contains the following structure / files:

index.html
images
image1.jpg
image2.jpg
image3.jpg
styles
style.css
content
home.html
chapter.html
footer.html

From what I saw he saves the way to decompress
index.html
images \ image1.jpg
images \ image2.jpg
images \ image3.jpg
styles \ style.css
content \ home.html
content \ chapter.html
content \ footer.html

See that the position in the windows of the bar is \ however in this position the
php interprets that it is to disregard the next character getting
so the paths in linux:
index.html
images \ mage1.jpg
images \ mage2.jpg
images \ mage3.jpg
styles \ tyle.css
content \ ome.html
content \ apitulo.html
content \ ooter.html

The root files are successfully extracted but the others generate
all wrong files.

Expected result:
----------------
That the files are extracted correctly both those generated in the
windows and extracted in linux and vice versa.

Actual result:
--------------
The files are extracted all with problem.

Thank you for taking the time to write to us, but this is not

ZipArchive is very liberal in what it accepts as filename (i.e.
$localname), and as such accepts backslashes.  The documentation
of ZipArchive::addFile()[1] (and other relevant methods) states:

| For maximum portability, it is recommended to always use forward
| slashes (/) as directory separator in ZIP filenames.
