Break if no file found in directory

Peuplarchie · 11-17-2008, 01:17 AM

Good day to you,
I have a function which return an array of files.
I would need it to break if there is no file in the directory.

Here is the code :

PHP Code:


			
function compileList($extensions)
{
     if ($handle = opendir('.')) {
   while (false !== ($file = readdir($handle)))
      {
          $ext = strtolower(end(explode('.', $file)));
       
          if (in_array($ext, $extensions) AND $file != "." AND $file != "..")
              {
                  $files[$file]=implode(file($file));
              }
       }
  closedir($handle);
  }
  return $files;
         
}

Thanks !

How about something like this? Would this do the job for you?

php Code:

function get_files_by_extension($szDirectory, array $aExtensions)
{
    $szExtensions = vsprintf('*.%s', implode(',*.', $aExtensions));
    $szGlob = sprintf('%s/{%s}', rtrim($szDirectory, '/'), $szExtensions);
    return glob($szGlob, GLOB_BRACE | GLOB_NOSORT);
}

print_r(get_files_by_extension('myDirectory', array('php', 'ico', 'gif')));
