Example#1FilesystemIterator::key()example

This example demonstrates the difference between theFilesystemIterator::KEY_AS_PATHNAMEandFilesystemIterator::KEY_AS_FILENAMEflags.

<?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";
}
?>

以上例程的输出类似于：

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