Can somebody explain why the following works...

PHP Syntax (Toggle Plain Text) 
  1. <?php
  2. system("ls /home/hans/");
  3. ?>

and this not.....

PHP Syntax (Toggle Plain Text) 
  1. <?php
  2. system("cp /home/hans/data.txt /home/hans/data.tx2");
  3. ?>

For the life of me, I can't figure it out. I simply want to copy a file, so why won't php let me do this? Please help, because I'm getting a little frustrated. --Hans

hmm..

Maybe check the file permission of the folder,maybe the permission is limited.try to change it to 777.

do you run this script as owner of this home directory? or you can try chmod 777
Keep in mind that I'm not native english speaker....
