Compressing ZIP files in a linux server with PHP

I am trying to create a .zip file of a folder in linux.

First I go where the compressed folder is:

shell_exec('cd /var/www/vhosts/website/test/');

The folder test has the folder testzip which should be zipped and sent somewhere else:

shell_exec('zip a -r -tzip /var/www/vhosts/website/zip/save/testzip.zip /var/www/vhosts/website/test/testzip');

This should create testzip.zip. Somehow this doesn’t work.

Could anyone help?

Answer

Try with

"zip -a -r ..."

instead of

"zip a -r ..."

— EDIT —

Reading the comment of Mark Adler, I realized that you’re using zip with 7-zip parameters.

So… are you sure that your zip is a link to 7z?

Anyhow, I suggest you to avoid ambiguities: is your intention is use 7z, explicit it with

"7z a -r -tzip ..."

If you want call the zip executable, use a correct zip syntax.

p.s.: sorry for my bad English
