Copy Function Errors

Hi, I have a snippet of code here: shell_exec("tar cvf /var/www/html/test/$id/data.tar /var/www/html/test/$id/data"); $file1="http:/www.mysite.com/test/$id/data.tar"; $file2="http://www.mysite2.com/test/$id/.tar"; copy($file1,$file2); I got the following error in the access log of the server: [Wed Jul 16 15:45:57 2008] [error] PHP Warning: copy(http://www.mysite.com/test/145/data.tar) [<a href='function.copy'>function.copy</a>]: failed to open stream: HTTP wrapper does not support writeable connections. in /var/www/html/beam_calculation.php on line 20 Is there something I could do here to allow my file be "copied" to the remote server? Anything is appreciated. Alice ====================================================== Alice Wei MIS 2009 School of Library and Information Science Indiana University Bloomington ajwei@indiana.edu
