    示例 #1 SplFileInfo::getFilename() example

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

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

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

    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.

    // 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();
