How to access the first file of a Finder::files() result?

Question

How can I get the first file with symfony/finder component?

I tried to do like this:

<?php
// ...
$finder = new Finder();
$finder
    ->files()
    ->in($this->getKernel()->getRootDir().'/../web/uploads/')
    ->name($filename);

    if (!$finder->count()) {
        throw new NotFoundHttpException('Image not found');
    }

    dump(
        $finder->count(), 
        $finder->getIterator()->current(), 
        $finder->getIterator()->valid()
    );

and I get this result:

1
null
false

Answer 1

$iterator = $finder->getIterator();
$iterator->rewind();
$firstFile = $iterator->current();

Answer 2

Try to rewind first or \var_dump(\iterator_to_array($finder));.

The sequence of an iterator is:

• rewind
• valid
• current/key
• next
• valid
• current/key
• next
• ...
