SplFileInfo::getBasename — Gets the base name of the file
$suffix = ""): string
This method returns the base name of the file, directory, or link without path info.
SplFileInfo::getBasename() is locale aware, so for it to see the correct basename with multibyte character paths, the matching locale must be set using the setlocale() function.
suffix
Optional suffix to omit from the base name returned.
Returns the base name without path information.
示例 #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：
string(8) "file.txt" string(8) "file.txt" string(4) "file"
