本文实例讲述了PHP基于单例模式实现的数据库操作基类。分享给大家供大家参考，具体如下：
配置文件：
'localhost',
'user'=>'root',
'password'=>'',
'database'=>'test',
)
?>
php 数据库基类：
<?php
class db {
public $conn;
public static $sql;
public static $instance=null;
代码如下:using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; namespace
代码如下: using System; using System.IO; using System.Text; using System.Data; using System.Web.UI; using System.Web.UI.WebControls; namespace ec { /// /// 文件操作类 /// public class FileObj : IDisposable { private bool _alreadyDispose = false; #region 构造函
using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; namespace EC {
