Finder Component

Finder finds files and directories via an intuitive fluent interface.

use Symfony\Component\Finder\Finder;

$finder = new Finder();

$iterator = $finder
  ->files()
  ->name('*.php')
  ->depth(0)
  ->size('>= 1K')
  ->in(__DIR__);

foreach ($iterator as $file) {
    print $file->getRealpath()."\n";
}

But you can also use it to find files stored remotely like in this example where we are looking for files on Amazon S3:

$s3 = new \Zend_Service_Amazon_S3($key, $secret);
$s3->registerStreamWrapper("s3");

$finder = new Finder();
$finder->name('photos*')->size('< 100K')->date('since 1 hour ago');
foreach ($finder->in('s3://bucket-name') as $file) {
    print $file->getFilename()."\n";
}
