文件重命名在Web服务器上失败

Question

I have the following script which works fine locally:

    <?php

//Report all errors
error_reporting(E_ALL);

if ($handle = opendir('instance/system/application/images/dir/testimages/')){

    while (false !== ($fileName = readdir($handle))){
        $newName = str_replace(" ", "_", $fileName);
        rename($fileName, $newName);
    }

    echo "All files have been renamed";
    closedir($handle);
}
?>

However when run on the web server I get the following error:

Warning: rename(.,.) [function.rename]: Permission denied in C:\inetpub\vhosts\domain.com\httpdocsename.php on line 10

Any idea how I can resolve this?

Cheers

Note:

I am using IIS7 and a windows server.

Couple of things:

In windows, go to the directory where you want to rename files, right click, and look at the permissions for both the folder and the files within. Whatever the process is running the web server needs to have permissions to modify those files, or create new files in the directory.

Secondly, and more subtly - I think the root cause is a bug. In the PHP manual, there's a comment suggesting that rename will put the file in the current working directory unless you specify your full directory path in the "to" argument. So, if you are trying to rename "c:\instance/system/application/images/dir/testimages/banana pic.jpg" to banana_pic.jpg, your current code will write that to the current working directory - probably the location of php.exe - that will fail.

I'd try to specify the folder in which you want the renamed file to be placed, and see if that works...
