image upload / system copy... failure

[Anon]

I'm not using the latest version of PHP, so I don't have the automatic copy_uploaded_file function, so I'm trying to use exec() or system() to do a copy...

I get the temporary file name of the photo that was uploaded sitting in /tmp and I get its actual file name...

I print the command out before executing to make sure it's good, and it always is...
something like this is what comes out

mv /tmp/phpuShXxk /home/devfederal/photos/jeep.jpg

By inserting a while(1); in my code, I was able to freeze execution long enough to go to /tmp and verify that the file existed, and it did. Everything is fine, but when I pass the above command to system() or exec() it doesn't do anything... I even tried using `` back ticks to execute it... When I try to echo the result, nothing appears, even after saving the result to a var and then printing, as was recommended before.

I'm about to go insane. I can't figure out why the bloody mv isn't working. Is there some sort of security problem with system() that needs to be addressed in php.ini? I didn't see anything when I looked.

Any help appreciated...

Luke,

Instead of doing a system command, I'd recommend you do a file copy using the fread/fwrite functions: It will be more portable for you.

For example:

$f1 = fopen("file1", "r");
$f2 = fopen("file2", "w");

if($f1 && $f2)
{
$content = fread($f1, filesize("file1"));
fwrite($f2, $content);

  fclose($f1);
  fclose($f2);
  unlink("file1")   // Delete first file.         

}
else
{

echo "File copy failed!";
}

Please note that this snippet will zap memory like crazy on large files.

Hope this helps,

Mark.
