PHP recursive directory traversal implementation program

PHP itself has a readdir function, but it can only read the current directory. Based on this function, I wrote another function to achieve my needs. The principle of the function is very simple, mainly using recursive calls.

The code is as follows

代码如下

复制代码

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.=”

”.$item.”

n”;
return $this->tostring;
}
}
$wapdir=”jquery”;
$d=new listdir($wapdir);
echo $d->tostring();
?>

Copy code

class listdir{

var $depth;
var $dirname;

var $list;

代码如下

复制代码

function mkdirs($dir)
{
if(!is_dir($dir))
{
if(!mkdirs(dirname($dir))){
return false;
}
if(!mkdir($dir,0777)){
return false;
}
}
return true;
}
mkdirs('div/css/layout');

同样的思路，php用rmdir和unlink递归删除多级目录的代码：

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

$this->tostring=””;

$this->getlist($path); }else{ $this->list[$this->depth][]=$item;

}

} } $this->list[$this->depth]['directory']=$dir; $this->depth-=1; $d->close(); return $this->list; } //Character channeling result function tostring($dir=""){ if($dir==””)$dir=$this->dirname; $d=@dir($dir); $this->tostring.=”

”.$item.”

n”; return $this->tostring; } } $wapdir=”jquery”; $d=new listdir($wapdir); echo $d->tostring(); ?> Recursively create multi-level directories 1. First determine whether the bottom directory div/css/layout exists; 2. Determine whether the upper directory div/css of div/css/layout exists. If it does not exist, use div/css as a parameter to proceed recursively The following is the program code:

The code is as follows
