renaming files

Hi, I got an image gallery script, that requires that the images are called 0, 1, 2, 3, etc...

And I was thinking, if the photograph brings me 300 pics, it'll be REALLY boring to rename them all manually.. so I was wondering if it's possible to rename them with a script.

Something like:

PHP Code:


			


if ($handle = opendir($path)) {

    

        $totalPics = 0;

        while (false !== ($file = readdir($handle))) {

        

            if ($file != "." && $file != "..") {      

                do something here      

            }            

        }       

        closedir($handle);

}

Something like that to loop through the folder, and if I already have 0, 1, 2, 3, and the next file is called IMG214, it gets renamed to 4, and thjen 5, 6, 7, etc.. you get the point..

Would this be a good way of achieving that? And if so, how would I do it?

For the actual renaming of the files, there is a really handy function: rename() (PHP manual page)

It might be good if you also use the glob() function to retrieve the list of files that need to be renamed. Wildhoney wrote an overview on this function in Traverse Directories the Easy Way with Glob() !

So something like this then?

PHP Code:


			
$images = glob($path.'*.jpg', GLOB_BRACE | GLOB_NOSORT);
$i = 0;

foreach($images as $image) {

        if($image != $i) {
              $rename = rename($path.$image, $path.$i.$format)
              if($rename) {
                     echo 'File: ' .$image. ' was renamed to ' .$i.$format;
              }
              else {
                     echo 'File: ' .$image. ' could not be renamed to ' .$i.$format. ', please check your chmodding!';
              }
        }
        else {
               echo 'File: ' .$image. ' was skipped because it has already the required name!';
        }

        $i++;

}

Yes?
