[RESOLVED] rename function - "Result too large"

elthamare

Hi,

i'm trying to rename a folder. This function works perfectly in linux, but when i'm using it in Windows (XP) it shows a Warning and the message "Result to large".

The name of the folder is the session hash, so yes, it's a bit long, but it never was a problem. The destination folder is made using a year/month/day/id path, so the function call is something like:
[FONT="Courier New"]rename(E:\xampp\htdocs\application..\tmp/files/ggegeqbq26619ckpj6a2100275,E:\xampp\htdocs\application..\performance01/procedures/16/2010/05/20/21)
[/FONT]

I'm using PHP 5.3.

Any ideas?

Thank you.

have u tried by enclosing the paths in single quotes?

You might also try using the same directory separator character (preferrably the correct one) throughout the entire path.

I have tried using the correct path separator ('\') with no results. Also, using single or double quotes didn't work either.

I'm calling the function like this:

rename ($dir,$newpath_dir);

The parameters $dir and $newpath_dir are in my first comment. In the warning line they have no quotes, but they are two strings.
The full message is:

Warning: rename(E:\xampp\htdocs\application\..\tmp/files/pfm51u1enjjuejqaci15u49nb5,
E:\xampp\htdocs\application\..\performance01/procedimientos/16/2010/05/20/26): 
Result too large in E:\xampp\htdocs\library\form.php on line 474

And the line 474 is where the rename function is.

I'm still trying to figure why is this happening, but I have no clue.

Consider using '/' throughout instead. PHP knows what the directory separator is on the platform it's running on, and will replace '/' with whatever is appropriate when it is given something that is supposed to be a file path.

The reason I suggest '/' is that since '\' is the escape character in PHP strings, if you write a literal [font=monospace]"path\to\file"[/font] string, then PHP will interpret that as having a tab character in it. But then that would show up in the error message....

One other suggestion I can make is to use

rename(realpath($dir), realpath($newpath_dir));

to remove the ".." steps, just in case those are throwing something off (though they shouldn't, in my opinion...).

I've never seen that error myself (and I can't even find it in PHP's source code for either 5.3.0 or 5.3.2 to track it down that way!), so aside from those suggestions and pending any further information I'm at a loss.

Ok, I have solved it. In linux I had to use mkdir to create newpath_dir with the right permissions, but it caused this problem, although this function is supposed to ignore the "mode" parameter in windows.
Using rename without calling mkdir first is working.

Thanks for the help 🙂
