txtSQL简单例子

这几天为了文库的事情在学txtSQL，这款开源的文本数据库确实功能很强大。虽然还欠缺一些功能，不过也已经足够用了。一边看帮助手册一边写了一些简单的例子，等什么时候有空翻译一下他的帮助手册好了（里面还有一些错误需要修订）

<?php
   include('./txtSQL.class.php');
   $sql = new txtSQL('./data');
   $sql->connect('root', 'bar'); 
   
   /*创建数据库
   $sql->createdb(array('db' => 'demo')) or die('Error creating txtSQL DB, txtSQL said: '.$sql->get_last_error());
   */
  
  /*选择数据库*/
   $sql->selectdb ( 'demo' );
  
   /*创建表

                 'name'  => array('type' => 'string', 'max' => 50), 
                 'email' => array('type' => 'string', 'max' => 50) 
                 );
   foreach($columns as $k => $v){
