	$tmp = explode('.', $file);
	
	rsort($tmp); // 翻转数组
	
	$ret['type'] = $tmp[0]; // 文件类型
	
	array_shift($tmp); // 从数组中摘除首元素
	
	rsort($tmp);
	
	$ret['filename'] = implode('.', $tmp); // 文件名
	
	$ret['createtime'] = date('Y-m-d H:i:s', filectime($file)); // 创建时间
	
	$ret['updatetime'] = date('Y-m-d H:i:s', filemtime($file)); // 最后一次更改时间
	
	$ret['size'] = filesize($file).'(Byte)';
	
	// 按行读取文件
	$fp = fopen($file, 'r');
	$i = 1;
	while(! feof($fp))
	{
		$lines[$i] = fgets($fp);
		$i++;
