This example will list the contents of the directory containing the script.
<?php
$iterator = new DirectoryIterator(__DIR__);
while($iterator->valid()) {
$file = $iterator->current();
echo $iterator->key() . " => " . $file->getFilename() . "\n";
$iterator->next();
}
?>
The above example will output
something similar to:
0 => .
1 => ..
2 => apple.jpg
3 => banana.jpg
4 => index.php
5 => pear.jpg
