SplFileInfo::isFile — Tells if the object references a regular file
Checks if the file referenced by this SplFileInfo object exists and is a regular file.
此函數沒(méi)有參數。
Returns true if the file exists and is a regular file (not a link), false otherwise.
示例 #1 SplFileInfo::isFile() example
<?php
$info = new SplFileInfo(__FILE__);
var_dump($info->isFile());
$info = new SplFileInfo(dirname(__FILE__));
var_dump($info->isFile());
?>
以上例程的輸出類(lèi)似于：
bool(true) bool(false)
