    var_dump($info->getRealPath());

    $info = new SplFileInfo('/tmp');
    var_dump($info->getRealPath());

    $info = new SplFileInfo('/I/Do/Not/Exist');
    var_dump($info->getRealPath());

    Note that due to realpath caching this method will return false when the file has been renamed or unlinked by other processes.

    Example:

    <?php
    $info     = new SplFileInfo('example.php');
    $info->getRealPath(); // /path/to/example.php

    rename('example.php', 'foobar.php');

    $info->getRealPath(); // false
    ?>
