这是我到目前为止:
<!DOCTYPE HTML>
<html>
<head>
<title>Tooltip Testings</title>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />
<style type="text/css">
body { margin: 60px auto; } p { padding:0; margin: 4px auto; text-align: center; }
</style>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.min.css" />

<script type="text/javascript">
$(function() {
$(document).tooltip({
items: '.tooltip',
show: 100,
hide: 500,
position: { my: 'center bottom', at: 'center top' },
content: function( callback ) {
var msgid = this.id.split('_')[1];
$.ajax({
type: 'post',
url: '/tooltip.php',
data:'i='+msgid,
success: function( data ) { callback( data …我有以下内容:
<?php
$path = '/home/user/test';
$dir = new RecursiveDirectoryIterator( $path );
$iterator = new RecursiveIteratorIterator( $dir );
$dir_iterator = new RegexIterator( $iterator, '/^.+\.php/i', RecursiveRegexIterator::GET_MATCH );
?>
到目前为止这么好,但我需要反转结果,归档与array_reverse()相同的效果
我试过这样,没有成功:
<?php
$dir_iterator = array_reverse( (array)$dir_iterator );
?>
另外,我如何获得返回的结果数量？我试过这个,但是没有用:
<?php
$total_results = count( $dir_iterator );
?>
有人可以帮帮我吗？
提前谢谢了!
