Description:
------------
I write a few line of code with rename() function in PHP.
It works well on Windows then I run the same code on CentOS but it doesn't work. I have do idea what's going on.My code is
<?
$i=rename("/root/Desktop/sad.txt","/root/Desktop/sad2.txt");
if($i==true)
echo "OK";
else
echo "not OK";

?>
The file permission is already like this.

-rwxrwxrwx 1 root root        0 Dec 14 19:59 sad

I checked out php.ini file.Safe mode is OFF.

Can anybody please help me ? I am new to this.


thank you in advance.
