shell - Zipping files through shell_exec in PHP: problem with paths -


I am working on the part of a web backup service whereby the user downloads a zip file containing those files

The zipping process is done through shell_exec command, which is supported by whatever they have chosen, to work. To work, I used the zip command to send the Apache user to non- The password has been provided by Adobe Edwards.

My problem is because I can not do "sudo cd / path / to / user / files" to specify the full path path for the files to zip me into a folder with user's backup files Required, which then goes to the zip file which I do not want.

What do I mean here:

Users have a backup of their files of 'test1', which are stored as follows /
/ backup / test1 / my pics / pic1.jpg

/ home / backup / test1 / my pics / Pic2.jpg

Home / Backup / Test 1 / My Picture / pic3.jpg

Home / Backup / Test 1 / Heilo. Txt
/home/backups/test1/music/band/song.mp3

When these files are zipped, they keep the full path, but I want to show it:
My Pictures / pic1.jpg
My Pictures / pic2.jpg
My Pictures / pic2.jpg
My Pictures / pic2 .jpg
hello.txt
music / band / song.mp3 < / P>

Is there a way to tell the zip to reduce the path, or specify a custom path for each file?
Or is there any way that I can change the job, put the directory in the user's root backup folder so that I can only specify the relative file path.

Thank you for reading, hope you got it and it all makes sense!

I have a little question about why you are making a dangerous system shell call when many good PHP speeding classes Show how easily to create a square which will output a zip file to the browser. There are also many classes at Phpclasses.org,

If you have my suggestions for doing this with a system call:

The file you want Can use, to reduce its path.

Can not you increase the zip executable permissions that Apache can use without using sudo?
