HomeBackend DevelopmentPHP Tutorial单一index.php实现PHP任意层级文件夹遍历(Zjmainstay原创)_php实例

以下是核心文件:
index.php文件

复制代码 代码如下:

header('Content-Type:text/html charset:utf-8');
date_default_timezone_set('PRC');
$rootDir = 'listFile'; //站点根目录,装载本程序所有文件
//站点base_url设置方法:
//考虑到通用性,现默认使用方法二,修改方法时注意同时修改.htaccess文件
//方法一:设置站点目录为根目录
//对应.htaccess:
//#RewriteBase /
// $base_url = 'http://www.listfile.com/';
//方法二:设置站点子目录为根目录
//对应.htaccess:
//RewriteBase /listFile/
$base_url = 'http://www.test.com/' .$rootDir .'/';
//解析文件夹路径
if(empty($_GET['return'])){
$dir = '.';
}else {
$dir = trim(array_pop(explode($rootDir,$_GET['return'])),'/');
if(empty($dir)) $dir = '.';
else $dir = './' . $dir;
}
// echo $dir; //当前文件夹
//遍历当前文件夹
$pattern = '*'; // '*'搜索全部文件,可以智能匹配,如*.jpg 搜索jpg文件,*.{jpg,png}搜索jpg和png文件,区分大小写!!
$skip = '*.skip'; //排除.skip类型文件(对应了“被跳过输出文件.skip”),你可以自己修改,如*.php排除所有php文件
$files = scandir_through($dir,$pattern,$skip,false);
?>



List Files








//文件类型数组
$filetypes = array(
'txt' => 'txt文本文件',
'dir' => '文件夹',
'php' => 'php文件',
'css' => 'css文件',
'js' => 'js文件',
'doc' => 'Word文档',
'xls' => 'Excel工作表',
'jpg' => 'jpg图片文件',
'gif' => 'gif图片文件',
'png' => 'png图片文件',
'mp3' => 'mp3文件',
'zip' => 'zip压缩包',
'rar' => 'rar压缩包',
'htm' => 'htm网页文件',
'html' => 'html网页文件',
'undefined'=>'文件类型未知',
);
//自定义屏蔽输出文件
$skipfiles = array(
'index.php',
'index.html',
'jquery-1.6.2.min.js',
'main.js',
'base.css',
);
//按规律输出当前文件夹所有文件
echo "";
echo "
";
echo "
名称
大小
";
echo "
类型
修改日期
";
foreach($files['filename'] as $index => $file){
if(in_array($file,$skipfiles)) continue;
if(is_null($filetypes[$files['ext'][$index]])) $filetype = '文件类型未知';
else $filetype = $filetypes[$files['ext'][$index]];
echo "
";
echo "
{$files['filesize'][$index]} 
{$filetype}
";
echo "
{$files['filemtime'][$index]}
";
}
echo '
';
?>


//文件夹遍历函数
function scandir_through($dir,$pattern='*',$skip=false,$subInclude=true,$flag=GLOB_BRACE){
$files = array();
//获取当前目录下所有文件及文件夹
$items = glob($dir . '/*');
//遍历所有项目,若设置$subInclude为true,则继续遍历子目录
for ($i = 0; $i if ($subInclude && is_dir($items[$i])) {
$add = glob($items[$i] . '/*');
if($add === false) $add = array();
$items = array_merge($items, $add);
}else {
$slash = strrpos($items[$i],'/');
$dir = substr($items[$i],0,$slash);
//若当前文件匹配文件查找模式$pattern,则加入$files数组中
if(in_array($items[$i],glob($dir.'/'.$pattern,$flag)) && (($skip===false) || !in_array($items[$i],glob($dir.'/'.$skip,$flag)))) {
$files['filemtime'][] = date('Y-m-d H:i:s',filemtime($items[$i])); //放这里为了解决iconv后中文名文件获取时间失败问题
$items[$i] = iconv('gb2312','utf-8',$items[$i]);
$file = substr($items[$i],$slash+1);
$files['widthDir'][] = $items[$i];
$files['filename'][] = $file;
if(is_dir($items[$i])) {
$files['ext'][] = 'dir';
$files['filesize'][] = '';
}else {
$files['filesize'][] = ceil(filesize($file)/1024).'KB';
if(strrpos($file,'.') === false) $files['ext'][] = 'undefined';
else $files['ext'][] = strtolower(array_pop(explode('.',$file)));
}
}
}
}
return $files;
}
/*
//.htaccess 文件,位于根目录下,原理:访问路径非文件,即文件夹,因此跳转至根路径下做解析。
RewriteEngine on
#一级目录法
#RewriteBase /
#二级目录法
RewriteBase /listFile/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*) index.php?return=%{REQUEST_FILENAME} [L]
*/
?>

JS文件
复制代码 代码如下:

$(document).ready(function(){
//根节点删除返回链接
if(window.location.href == base_url) $("#back").hide();
//返回处理
$("#back a").click(function(){
if(autoClickUrl != ''){
//Add baddir for click back.
var url = autoClickUrl;
}else{
var url=window.location.href;
}
if(url == base_url) return false; //如果在根节点触发返回链接,直接返回。
url = url.replace(location.search,''); //如果链接携带?return,截除return后续内容(由.htaccess生成)
url = url.substr(0,url.length-2); // 从url后第2位开始,避免/#情况存在时跳转错误
url = url.substr(0,url.lastIndexOf('/')+1); //截除最后一层文件夹,后退一级
window.location.href = url;
return false; //处理完毕,返回false阻止标签点击后的跳转。
});
if(autoClickUrl != '') $("#back a").click()
});

CSS文件
复制代码 代码如下:

#container{
border: 1px solid;
margin: 0 auto;
padding: 10px;
width: 654px;
border-radius: 10px 10px 10px 10px;
}
#back{
width: 654px;
margin: 0 auto;
}
#back a{
line-style:none;
}
.file{
clear: both;
height: 2px;
margin-bottom: 20px;
}
.file img{
float:left;
}
.file a{
float:left;
margin-left: 5px;
}
.file div{
float:left;
width:150px;
}
.text-left{
text-align:left;
}
.text-center{
text-align:center;
}
.text-right{
text-align:right;
}
.border-left{
border-left:1px solid;
}
.border-right{
border-right:1px solid;
}
.file div.filename{
width:200px;
}
.file div.filesize{
width:100px;
}
.file div.filemtime{
width:200px;
}

.htaccess文件
复制代码 代码如下:

#原理:访问路径非文件,即文件夹,因此跳转至根路径下做解析获取当前目录下的所有文件并列出。
RewriteEngine on
#一级目录法
#RewriteBase /
#二级目录法
RewriteBase /listFile/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*) index.php?return=%{REQUEST_FILENAME} [L]

核心文件夹:listFile/images/
效果图如下:
//listFile

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
