范例

SplFileInfo::__toString() example

<?php
$info = new SplFileInfo('foo');
var_dump($info->__toString());
echo $info.PHP_EOL;
$info = new SplFileInfo('/usr/bin/php');
var_dump($info->__toString());
echo $info.PHP_EOL;
?>

以上例程的输出类似于：

string(3) "foo"
foo
string(12) "/usr/bin/php"
/usr/bin/php 

It returns the exact $file_name string provided in the constructor, without further processing, normalisation or verification.
