    SplFileInfo::getRealPath — Gets absolute path to file

    Description

    public SplFileInfo::getRealPath(): string|false

    This method expands all symbolic links, resolves relative references and returns the real path to the file.

    Parameters

    This function has no parameters.

    Return Values

    Returns the path to the file, or false if the file does not exist.

    Examples

    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());
    ?>

    The above example will output something similar to:

    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
    ?>
