[RESOLVED] how can this be coded with ereg()?

mband2000

I'm not good at all with ereg.. and I need a little help.

I'm trying to loop through a folder to delete all files that don't have the .jpg extension. So I'm guessing the best thing to do is use ereg().

How can I write the ereg so that it works with what I'm trying to do.

$string = "images/jpeg";
$pattern="/(.+?).(jpg|jpeg)/i";
$replace="";
echo preg_replace($pattern,$replace,$string);

Hi!

Try this:

//---------------------------------------------------------------
function listDir($dirname)
{      

   $list = array();

   if(!$dp = opendir($dirname))
		return false;

   while($item = readdir($dp)) {
      if($item != '.' && $item != '..') {
         $fullName = $dirname.'/'.$item;

     if(is_file($fullName))
        $list[] = $fullName;
     }

   return $list;
}
//---------------------------------------------------------------

$fileList = listDir('myDir');

if($fileList === false)
   echo 'Couldn`t open the directory for reading.';
else {
   foreach($fileList as $file) {
      $extension = strtolower(substr($file, strrpos($file, '.') + 1));
      if($extension != 'jpg')
         unlink($file);
      }
   }

Thanks everyone for your help... gammaster I'm using your code.

But now I have a little problem with it.. I made the mistake of saying I want to DELETE the file.

I actually want to rename the file using the .jpg extension.

I tried using this:

exec("ren ".$file." ".$file.".jpg");

but I keep getting CGI error messages and I was getting a folk message at one point.. I'm on a windows server.

So how can I RENAME the files instead of delete them?

I haven't slept ALLLLL night trying to figure out what was wrong with the code.. and all I had to do was use the rename() fuction!!!

Thanks gammaster!!
