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());
?>

Il precedente esempio visualizzerà qualcosa simile a:

string(28) "/private/tmp/phptempfile.php" 
string(12) "/private/tmp"
bool(false)
bool(false)
string(12) "/private/tmp"

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
?>
