I was trying to work out the difference between this and getBasename (http://php.net/manual/splfileinfo.getbasename.php) and the only difference I could really see was a special case of a file in the filesystem root with the root specified:
<?php
function getInfo($reference)
{
$file = new SplFileInfo($reference);
var_dump($file->getFilename());
var_dump($file->getBasename());
}
$test = [
'/path/to/file.txt',
'/path/to/file',
'/path/to/',
'path/to/file.txt',
'path/to/file',
'file.txt',
'/file.txt',
'/file',
];
foreach ($test as $file) {
getInfo($file);
}
// will return:
?>

It should be mentioned that the function returns the name of the directory if "filename" is of type "directory". Hence
<?php
$info = new SplFileInfo('/path/to/');
var_dump($info->getFilename());
?>
should return "to"
The function name is kind of misleading here and I am glad to have it tried.
