 代码如下 复制代码
function DeltreeDir($dir)  {
$dir = realpath($dir);
        if (!$dir || !@is_dir($dir))
                return 0;
        $handle = @opendir($dir);
        if ($dir[strlen($dir) - 1] != DIRECTORY_SEPARATOR)
                $dir .= DIRECTORY_SEPARATOR;
        while ($file = @readdir($handle))    {
                if ($file != '.' && $file != '..')         {
                        if (@is_dir($dir . $file) && !is_link($dir . $file))
                                DeltreeDir($dir . $file);
                        else
                                @unlink($dir . $file);
                }
        }
        closedir($handle);
        @rmdir($dir);
}

//实例二

//循环删除目录和文件函数

 代码如下 复制代码
function delDirAndFile( $dirName )
{
if ( $handle = opendir( "$dirName" ) ) {
  while ( false !== ( $item = readdir( $handle ) ) ) {
   if ( $item != "." && $item != ".." ) {
   if ( is_dir( "$dirName/$item" ) ) {
   delDirAndFile( "$dirName/$item" );
   } else {
   if( unlink( "$dirName/$item" ) )echo "成功删除文件: $dirName/$item
";
   }
   }
   }
   closedir( $handle );
   if( rmdir( $dirName ) )echo "成功删除目录: $dirName
";
}
}

// 实例三

 代码如下 复制代码
function delFileUnderDir( $dirName="../Smarty/templates/templates_c" )
{
if ( $handle = opendir( "$dirName" ) ) {
   while ( false !== ( $item = readdir( $handle ) ) ) {
   if ( $item != "." && $item != ".." ) {
   if ( is_dir( "$dirName/$item" ) ) {
         delFileUnderDir( "$dirName/$item" );
   } else {
   if( unlink( "$dirName/$item" ) )echo "成功删除文件: $dirName/$item
";
   }
   }
   }
   closedir( $handle );
}
}

delDirAndFile( 'www.111cn.net');

//上面三种删除目录与目录下所有文件与空目录的实例,都是以遍历来做,也就是递归来一个个讲再判断就OK了。
