SplFileInfo::isDir — Tells if the file is a directory
This method can be used to determine if the file is a directory.
此函數(shù)沒(méi)有參數(shù)。
Returns true if a directory, false otherwise.
示例 #1 SplFileInfo::isDir() example
<?php
$d = new SplFileInfo(dirname(__FILE__));
var_dump($d->isDir());
$d = new SplFileInfo(__FILE__);
var_dump($d->isDir());
?>
以上例程的輸出類(lèi)似于：
bool(true) bool(false)
