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, PHP 8)
SplFileInfo::getRealPath — Gets absolute path to file
Descrizione
public SplFileInfo::getRealPath(): string|false
This method expands all symbolic links, resolves relative references and returns the real path to the file.
Elenco dei parametri
Questa funzione non contiene parametri.
Valori restituiti
Returns the path to the file, or false if the file does not exist.
Esempi
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"
