如何跨SMB安装进行PHP复制

Question

I have a simple script which copies a file from one SMB mount to another. The source file system is the same, but the web server is different. I'm using PHP to process the file by copying it to a temp directory, then performing additional tasks on it. This setup was working at one point in time but it seems that it's no longer working correctly. Can someone point me in the right direction?

fstab mounts:

//192.168.0.x/share /media/folder smbfs username=user,password=mypass
//192.168.0.x/share2 /media/folder2 smbfs username=user,password=mypass

php code:

copy('/media/folder/filename.txt','/media/folder2/temp/filename.txt');

Error:

Warning: copy(/media/folder2/temp/filename.txt): failed to open stream: Permission denied in /www/myphp.php on line xx

Folder permissions (not the mount, but the source folder on the fileserver):

/media/folder = 777 
/media/folder2/temp = 777

Answer 1

I changed the command to:

copy('/media/folder/filename.txt','/tmp/filename.txt');

Apparently it's more difficult to process files on an SMB share than I thought. The file should be removed when the computer's rebooted, or possibly at regular intervals, depending on the system setup.
