遍历目录,结果存入数组。支持php4及以上。php5以后可用scandir()函数代替while循环。

复制代码 代码如下:


/**
* @param string $dir
* @return array
*/
function my_scandir($dir)
{
 $files = array();
 if ( $handle = opendir($dir) ) {
  while ( ($file = readdir($handle)) !== false )
  {
   if ( $file != ".." && $file != "." )
   {
    if ( is_dir($dir . "/" . $file) )
    {
     $files[$file] = my_scandir($dir . "/" . $file);
    }
    else
    {
     $files[] = $file;
    }
   }
  }
  closedir($handle);
  return $files;
 }
}

function my_scandir1($dir)
{
 $files = array();
 $dir_list = scandir($dir);
 foreach($dir_list as $file)
 {
  if ( $file != ".." && $file != "." )
  {
   if ( is_dir($dir . "/" . $file) )
   {
    $files[$file] = my_scandir1($dir . "/" . $file);
   }
   else
   {
    $files[] = $file;
   }
  }
 }

 return $files;
}

$result = my_scandir('./');
$result = my_scandir1('./');
?>

另一个实现方法

复制代码 代码如下:


function fetchDir($dir) {
        foreach(glob($dir.'\*') as $file) {
            echo $file,"\n";
            if(is_dir($file)) {
                fetchDir($file);
            }
        }
    }
    fetchDir("D:\wamp\www\any");

还可以把‘\*', 换成 DIRECTORY_SEPARATOR.'*' ,把‘\n'换成PHP_EOL ,这样可以跨平台了。
