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
?>
