This method returns the base name of the file, directory, or link without path info.

Caution

范例

Example #1 SplFileInfo::getBasename() example

<?php
$info = new SplFileInfo('file.txt');
var_dump($info->getBasename());

$info = new SplFileInfo('/path/to/file.txt');
var_dump($info->getBasename());

$info = new SplFileInfo('/path/to/file.txt');
var_dump($info->getBasename('.txt'));
?>

以上例程的输出类似于：
