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.
