var_dump($info->getFilename());

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

$info = new SplFileInfo('http://www.php.net/');

// Careful, output is different for `filename` vs `getFilename`. Inconsistent behaviour.



$path = 'test.txt';



$pathInfo = pathinfo($path);

echo '<pre>';

print_r($pathInfo);



echo '<br>';

echo '***************';



$splFileInfo = new SplFileInfo($path);

echo '<br>';

echo $splFileInfo->getBasename();



echo '<br>';

echo $splFileInfo->getFilename();

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:

/*

string(8) "file.txt"

string(8) "file.txt"



string(4) "file"

string(4) "file"



string(2) "to"

string(2) "to"



string(8) "file.txt"

string(8) "file.txt"



string(4) "file"

string(4) "file"



string(8) "file.txt"

string(8) "file.txt"



string(9) "/file.txt" // see how getFilename includes the '/'

string(8) "file.txt"  // but getBasename doesn't



string(5) "/file"     // ditto getFilename

string(4) "file"      // ditto getBasename

*/

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.
