SplFileInfo::isDir — Tells if the file is a directory
This method can be used to determine if the file is a directory.
此函数没有参数。
Returns TRUE
if a directory, FALSE
otherwise.
Example #1 SplFileInfo::isDir() example
<?php
$d = new SplFileInfo ( dirname ( __FILE__ ));
var_dump ( $d -> isDir ());
$d = new SplFileInfo ( __FILE__ );
var_dump ( $d -> isDir ());
?>
以上例程的输出类似于:
bool(true) bool(false)
