不说废话，直接代码

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>dir scan </title>

</head>

<body>

<form method="post">

目录遍历：<input type="text" name="dir">

<input type="submit" value="查询">

<?php

$dir=@$_POST['dir'];

echo $dir."<hr/>";

if(is_dir($dir)){

$opdir=opendir($dir);

while(($file=readdir($opdir))!==false){

$filename=$dir.'//'.$file;

if(is_dir($filename)&&$filename!='.'&&$filename!='..'){

echo "目录:".$filename."<br/>";

}else if($filename!='.'&&$filename!='..'){

echo "文件:".$filename."<br/>";

}

}

closedir($opdir);

}else if(is_file($dir)){

$myfile=fopen($dir, "r") or die("Unable to open file!");

while(!feof($myfile)){

echo fgets($myfile)."<br/>";

}

fclose($myfile);

}else{

echo "no dir ";

}

?>

</form>

</body>

</html>
