示例 #1 RecursiveDirectoryIterator example
<?php
$directory = '/tmp';
$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));
$it->rewind();
while($it->valid()) {
if (!$it->isDot()) {
echo 'SubPathName: ' . $it->getSubPathName() . "\n";
echo 'SubPath: ' . $it->getSubPath() . "\n";
echo 'Key: ' . $it->key() . "\n\n";
}
$it->next();
}
?>
以上例程的输出类似于：
SubPathName: fruit/apple.xml SubPath: fruit Key: /tmp/fruit/apple.xml SubPathName: stuff.xml SubPath: Key: /tmp/stuff.xml SubPathName: veggies/carrot.xml SubPath: veggies Key: /tmp/veggies/carrot.xml
