范例

SplFileInfo::isDir() example

<?php
$d = new SplFileInfo(dirname(__FILE__));
var_dump($d->isDir());
$d = new SplFileInfo(__FILE__);
var_dump($d->isDir());
?>

以上例程的输出类似于：

bool(true)
bool(false)

Documentation is a bit misleading.
SplFileInfo->isDir() and other classes (e.g. DirectoryIterator->isDir()) return TRUE for symlinks of directories. Better use getType() method instead, which returns 'link' for symlinks.
This was reported long time ago - https://bugs.php.net/bug.php?id=72364 , but docs are still not fixed.
