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
?>
SplFileInfo::getRealPath
(PHP 5 >= 5.2.2, PHP 7)

Exemple
Example #1 SplFileInfo::getRealPath() example
<?php
$info = new SplFileInfo('/..//./../../'.__FILE__);
var_dump($info->getRealPath());
$info = new SplFileInfo('/tmp');
var_dump($info->getRealPath());
$info = new SplFileInfo('/I/Do/Not/Exist');
var_dump($info->getRealPath());
$info = new SplFileInfo('php://output');
var_dump($info->getRealPath());
$info = new SplFileInfo("");
var_dump($info->getRealPath());
