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.
此函数没有参数。
Returns TRUE
if the file exists and is a regular file (not a link), FALSE
otherwise.
Example #1 SplFileInfo::isFile() example
<?php
$info = new SplFileInfo ( __FILE__ );
var_dump ( $info -> isFile ());
$info = new SplFileInfo ( dirname ( __FILE__ ));
var_dump ( $info -> isFile ());
?>
以上例程的输出类似于:
