SplFileInfo::getRealPath — Gets absolute path to file
This method expands all symbolic links, resolves relative references and returns the real path to the file.
此函數沒(méi)有參數。
Returns the path to the file, or false if the file does not exist.
示例 #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());
?>
以上例程的輸出類(lèi)似于：
string(28) "/private/tmp/phptempfile.php" string(12) "/private/tmp" bool(false) bool(false) string(12) "/private/tmp"
