目录递归循环php代码

这是一款从代码和速度上还不错的php目录遍历代码，有需要的朋友可以参考一下。

代码如下	复制代码
$path = '..'; function get_filetree($path){ $tree = array(); foreach(glob($path.'/*') as $single){ if(is_dir($single)){ $tree = array_merge($tree,get_filetree($single)); } else{ $tree[] = $single; } } return $tree; } print_r(get_filetree($path));

在递归扫描文件夹树的问题上，还是 Glob 函数的表现好一点，很准确的说。 > Scandir 函数会莫名其妙扫描两次 ../ 处的文件，也就是说如果小邪有俩文件。

> ../b.php教程 和 ../a.php，结果就会在扫描报告上面出现两次，很是奇怪。

 

代码如下

复制代码

//Update at 2010.07.25 - 以下代码作废 $path = '..'; function get_filetree_scandir($path){ $tree = array(); foreach(scandir($path) as $single){ if(is_dir('../'.$single)){ $tree = array_merge($tree,get_filetree($single)); } else{ $tree[] = '../'.$single; } } return $tree; } print_r(get_filetree_scandir($path)); //Update at 2010.07.25 - 以下为新代码 $path = './'; function get_filetree_scandir($path){ $result = array(); $temp = array(); if (!is_dir($path)||!is_readable($path)) return null; //检测目录有效性 $allfiles = scandir($path); //获取目录下所有文件与文件夹 foreach ($allfiles as $filename) { //遍历一遍目录下的文件与文件夹 if (in_array($filename,array('.','..'))) continue; //无视 . 与 .. $fullname = $path.'/'.$filename; //得到完整文件路径 if (is_dir($fullname)) { //是目录的话继续递归 $result[$filename] = get_filetree_scandir($fullname); //递归开始 } else { $temp[] = $filename; //如果是文件，就存入数组 } } foreach ($temp as $tmp) { //把临时数组的内容存入保存结果的数组 $result[] = $tmp; //这样可以让文件夹排前面，文件在后面 } return $result; } print_r(get_filetree_scandir($path));

一款联动菜单，利用了js php mysql实现的无刷新效果，有需要的朋友可以直接下载哦。

上传原理很简单就是利用表单的打开方式为iframe的id名，这样就可以在当前页面的iframe打来了，实现文件上传，再利用js返回上传结果。

<html>
<head>
<title>无刷新上传文件</title>
<meta Content-type="text/html" charset="utf-8" />
<script type="text/网页特效">
function startUpload() {
document.getElementById('processing').innerHTML = 'loding...';
return true;
}
function stopUpload(rel){
var msg;
switch (rel) {
case 0:
msg = "上传成功";
break;
case 1:
msg = "上传的文件超过限制";
break;
case 2:
msg = "只能上传图片文件";
break;
default:
msg = "上传文件失败";
}
document.getElementById('processing').innerHTML = msg;
}
</script>
</head>
<body>
<div style="text-align:center">
<div id="processing"></div>
<form action="upload.php教程" method="post" enctype="multipart/form-data" target="form-target" onsubmit="startUpload();">

<input type="submit" name="sub" value="upload" />
</form>
<iframe style="width:0; height:0; border:0;" name="form-target"></iframe>
