php递归遍历目录

<?php
class listdir{
var $depth;
var $dirname;
var $list;
var $tostring;

function listdir($dir){
$this->dirname=$dir;
$this->depth=0;
$this->tostring=”";
}

//把结果保存进多维数组
function getlist($dir=”"){
if($dir==”")$dir=$this->dirname;
$d=@dir($dir);
while(false!==($item=$d->read()))
{
if($item!=”.”&&$item!=”..”)
{
$path=$dir.”/”.$item;
if(is_dir($path)){
$this->depth+=1;
$this->getlist($path);
}else{
$this->list[$this->depth][]=$item;
}
}
}
$this->list[$this->depth]['directory']=$dir;
$this->depth-=1;
$d->close();
return $this->list;
}

//字符窜化结果

function tostring($dir=”"){
if($dir==”")$dir=$this->dirname;
$d=@dir($dir);
$this->tostring.=”<UL>\n”;
$this->tostring.=”Directory:”.$dir.”\n”;
while(false!==($item=$d->read()))
{
if($item!=”.”&&$item!=”..”)
{
$path=$dir.”/”.$item;
if(is_dir($path)){
$this->depth+=1;
$this->tostring($path);
}else{
$this->tostring.=”<LI>”.$item.”</LI>\n”;
}
}
}
$this->depth-=1;
$d->close();
$this->tostring.=”</UL>\n”;
return $this->tostring;
}
}
$wapdir=”jquery”;
$d=new listdir($wapdir);
echo $d->tostring();
?>

输出结果：

<UL>
Directory:jquery
<LI>jquery-1.3.2.js</LI>
<LI>jquery-1.3.2.min.js</LI>
<LI>jquery-1.3.2-vsdoc2.js</LI>
<LI>test.html</LI>
<LI>common.js</LI>
<UL>
Directory:jquery/d
<LI>common.js</LI>
<LI>jquery-1.3.2.js</LI>
</UL>
</UL>
