Re: [PHP] scandir() in automount/autofs
2008. 01. 21, hétfő keltezéssel 20.23-kor shiplu ezt írta:
I configured autofs in my fedora so that when I plug any usb stick in
/dev/sda1 it automatically mounts in /mnt/auto/usb0
There is two lines where the problem arise.
$util-run_command(ls -1 /mnt/auto/usb0 | wc -l);// it shows 13 when I
plug my usb stick.
$list = scandir(/mnt/auto/usb0 ); // here $list is null
This script is in a php file which is running by apache.
the $util object is not actually running the command but it is inserting the
command in a queue. There is daemon who has root access processing the
queue.
It means the command in $util-run_command() is executing with root
privilege. this command mounts and get the total amount of file/folder very
nicely
But when I run the second line I see there is no file. How can I fill the
list with those file list.
It may look that the problem is regarding permission. But I don't think so.
Becasue I use the same command I mean the same 2 lines with /mnt/cdrom, and
it works very nicely
It works,
$util-run_command(ls -1 /mnt/cdrom | wc -l);// it shows 200 in my CD
rom drive
$list = scandir(/mnt/cdrom); // here I get full list of files/folders
Why its happening?
I'm pretty sure it is because of the permissions on the mounted usb
stick. for example my ubuntu automounts my usb stick with permissions
700 and user/group as me. so it would not be accessible by any other
user, except root. I think that's what happening in your case.
However, I do not know where you can set that up...

I want the $list to be filled. Also I need directory and file information so
that I can make another list like
array(array('Type'='DIR','Name'='music'),array('Type'='DIR','Name'='music1'),array('Type'='FIL','Name'='
elvis.mp3'),array('Type'='FIL','Name'='elvis2.mp3'),...);
