1.要点

2.程序举例

<?php	header("Content-type:text/html;charset=utf-8");	function my_scandir($dir){		$files=array();		if (is_dir($dir)) {			if ($handle=opendir($dir)) {				while (false!=($file=readdir($handle))) {					if ($file!='.' && $file!='..') {						if (is_dir($dir.'/'.$file)) {							$files[$file]=my_scandir($dir.'/'.$file);						}else{							$files[]=$dir.'/'.$file;						}					}				}				closedir($handle);				return $files;			}		}	}	//示例	$dir='G:/myenv/myweb/blog';	echo "<PRe>";	print_r(my_scandir($dir));	echo "</pre>";?>输出结果
Array(    [.phpintel] => Array        (            [0] => G:/myenv/myweb/blog/.phpintel/0955938697ff3f8ba2e7e99ad7d1a15f            [1] => G:/myenv/myweb/blog/.phpintel/2db17ac1fe7e91a24b81522ce47bc0f3            [2] => G:/myenv/myweb/blog/.phpintel/41ef0d7347d9771a82ff4f9ce3918f2c            [3] => G:/myenv/myweb/blog/.phpintel/4e8c5b9ab38f7c7cd83bf9f839940714            [4] => G:/myenv/myweb/blog/.phpintel/5af280c5d1540e3ebccd0f57875d45b4            [5] => G:/myenv/myweb/blog/.phpintel/621882ef54ef7a3bfc19b4e61e90e6f7            [6] => G:/myenv/myweb/blog/.phpintel/cff0d4807d663f1cb70b0ebb6d8dcea7            [7] => G:/myenv/myweb/blog/.phpintel/index        )    [0] => G:/myenv/myweb/blog/comment.php    [CSS] => Array        (            [0] => G:/myenv/myweb/blog/css/index.css        )    [1] => G:/myenv/myweb/blog/db.php    [images] => Array        (            [0] => G:/myenv/myweb/blog/images/1.jpg        )    [2] => G:/myenv/myweb/blog/index.php    [3] => G:/myenv/myweb/blog/login.php    [4] => G:/myenv/myweb/blog/magicClass.php    [5] => G:/myenv/myweb/blog/result.php)
