Directory Listing

[abhilashdas]

Can anybody tell me how to list the contents of a directory??
Not all files but the files of a specified file type.
I ve managed to display all files using readdir, but still dont know how to filter files of a particular type.
Hope you guys can help me
Thanx in adwance

this will grab any files in $dir with a filetype listed in $filetypes. make sure you add a "|" to the end of each filetype, including the last. wasn't sure if you were only looking to display one specific filetype, or multiple, so i did it this way.

<pre>
<?
  //the directory to look in
  $dir = "./";
  
  //this is a list of the valid filetypes, seperated by a "|"
  //make sure the last item also has a "|" at the end!
  $filetypes = "html|zip|";

  //start reading the directory
  if(is_dir($dir)){
    if($opendir = opendir($dir)){
      while(($file = readdir($opendir)) !== false){

        //find the last occurence of a period in the filename
        $typepos = strrpos($file, ".");

        //check if the typepos was returned
        // --> if not, it does not have a filetype, so we ignore it
        if($typepos > 0 && $file != ".."){

          //isolate the filetype
          $type = substr($file, $typepos + 1, strlen($file) - $typepos);

          //check if the filetype is something we want
          if(strpos($filetypes, $type . "|") !== false)
            echo $file . " - " . strtoupper($type) . " file\n";
        }
      }
      closedir($opendir);
    }
  }
?>
</pre>

hope it helps you out.

Thanx for the reply!!!
I was wondering whether there is a built in function to do so; just like dir() or so which accepts wild charecters to filter.
