Examples

Example #1 FilesystemIterator::key example

This example demonstrates the difference between the FilesystemIterator::KEY_AS_PATHNAME and FilesystemIterator::KEY_AS_FILENAME flags. 

<?php
$iterator = new FilesystemIterator(dirname(__FILE__), FilesystemIterator::KEY_AS_PATHNAME);
echo "Key as Pathname:\n";
foreach ($iterator as $key => $fileinfo) {
    echo $key . "\n";
}

$iterator->setFlags(FilesystemIterator::KEY_AS_FILENAME);
echo "\nKey as Filename:\n";
foreach ($iterator as $key => $fileinfo) {
    echo $key . "\n";
}
?>

Output of the above example in PHP 8.2 is similar to:

Key as Pathname:
/www/examples/.
/www/examples/..
/www/examples/apple.jpg
/www/examples/banana.jpg
/www/examples/example.php

Key as Filename:
.
..
apple.jpg
banana.jpg
example.php
