Example #1 SplFileInfo::isExecutable() example
<?php
$info = new SplFileInfo('/usr/bin/php');
var_dump($info->isExecutable());
$info = new SplFileInfo('/usr/bin');
var_dump($info->isExecutable());
$info = new SplFileInfo('foo');
var_dump($info->isExecutable());
?>
以上例程的输出类似于：
bool(true) bool(true) bool(false)
