it's an interesting thing about the rename() function:

the code which doesn't work:
<?php
$base = "/home/phanatic/temp/";
$from = "users";
$to = "userdata";
rename ($base.$from, $base.$to);
?>

and which works (if the script is in the same dir):
<?php
$from = "users";
$to = "userdata";
rename ("./".$from, "./".$to);
?>

error message for the first code:
Warning: rename(/home/phanatic/temp/users,/home/phanatic/temp/userdata) [http://www.php.net/function.rename]: No such file or directory in /home/phanatic/temp/test_rename.php on line 8

my configure line:
./configure --with-layout=GNU --with-mysql=shared --with-pgsql=shared --with-gd=shared --with-gd2 --enable-ftp --with-calendar --with-posix --
enable-sockets --enable-cli --enable-cgi --enable-pcntl --with-bz2=shared --with-zlib-dir=/usr/include/ --prefix=/usr --sysconfdir=/etc/php

hope i could provide all the infos needed to fix this problem...

The error is clear it can't find /home/phanatic/temp/users, probably because of permissions or probably because it's NOT the good directory. Are you sure ./ is /home/phanatic/temp/?

Anyway this is bogus, if you need any help please take a look at http://www.php.net/support.php .


Thank you for your report.

the file is there, i'm sure about it... and the script itself is in '/home/phanatic/temp', too!!! so it's not a bogus in my opinion... just test it yourself.

Can you please show us the permission of the directory and of the files please? 

It looks I really CAN NOT reproduce it there...

Thank you.

perms of the file:
-rw-r--r--    1 phanatic phanatic       99 Jan  5 10:36 users
perms of the dir:
drwxr-xr-x    5 phanatic phanatic     4096 Jan  5 12:06 temp

but in my opinion, if this happens because of the permissions, then why does the second script work?

thanx in advance...

Assuming that you run this script with the Command Line version (not through your webserver), can you run:

strace php yourscript.php

and put this output somewhere online? We should be able to figure out what fails in the script.
