Google 个性化主页类似，如何保存最后的布局一

MySQL由于它本身的小巧和操作的高效, 在数据库应用中越来越多的被采用.我在开发一个P2P应用的时候曾经使用MySQL来保存P2P节点,由于P2P的应用中,结点数动辄上万个,而且节点变化频繁,因此一定要保持查询和插入的高效.以下是我在使用过程中做的提高效率的三个有效的尝试.

Google 个性化主页类似，如何保存最后的布局二

增加中文水印
<?php
/*-------------------------------------------------------------
**描述：这是用于给指定图片加底部水印（不占用图片显示区域）的自定义类，需创建对象调用
**版本：v1.0
**创建：2007-10-09
**更新：2007-10-09
**人员：老肥牛([email]fatkenme@163.com[/email]  QQ:70177108)
**说明：1、需要gd库支持，需要iconv支持（php5已经包含不用加载）
        2、只适合三种类型的图片，jpg/jpeg/gif/png，其它类型不处理
        3、注意图片所在目录的属性必须可写
        4、调用范例：
            $objImg = new MyWaterDownChinese();
            $objImg->Path = "images/";
            $objImg->FileName = "1.jpg";
            $objImg->Text = "胖胖交友网 [url]www.ppfriend.com[/url]";
            $objImg->Font = "./font/simhei.ttf";
            $objImg->Run();
**成员函数：
----------------------------------------------------------------*/
class MyWaterDownChinese{
          var $Path = "./";  //图片所在目录相对于调用此类的页面的相对路径
          var $FileName = ""; //图片的名字，如“1.jpg”
          var $Text = "";   //图片要加上的水印文字，支持中文
          var $TextColor = "#ffffff"; //文字的颜色，gif图片时，字体颜色只能为黑色
          var $TextBgColor = "#000000"; //文字的背景条的颜色
          var $Font = "c://windows//fonts//simhei.ttf"; //字体的存放目录，相对路径
          var $OverFlag = true; //是否要覆盖原图，默认为覆盖，不覆盖时，自动在原图文件名后+"_water_down"，如“1.jpg”=> "1_water_down.jpg"
          var $BaseWidth = 200; //图片的宽度至少要>=200，才会加上水印文字。
        
//------------------------------------------------------------------
//功能：类的构造函数(php5.0以上的形式)
//参数：无
//返回：无
function __construct(){;}

Apache和PHP网页的编码问题分析

谈谈Apache和PHP网页的编码。还有一篇关于MySQL字符集的：http://potatows.eeie.cn/?p=39
谈到Apache的编码我们就要涉及到3个东西

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, http://www.drise.cn);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_NOBODY, true);
$order = curl_exec($ch);
echo ;
echo strip_tags($order);
echo ;
curl_close($ch);?>

有的服务器是看不到了,原因要根据服务器的配置而定了,在这里我就不多说了.

if(!mysql_num_rows($result)){exit("
alert(记录不存在!);history.back();
");}
$rs =mysql_fetch_object($result);
$file_name=substr($rs->path,strrpos($rs->path,"/")+1);
$file_dir =substr($rs->path,0,strlen($rs->path)-strlen($file_name));
$file_dir=realpath(str_replace(../,,$file_dir))."";
$rpath=$file_dir.$file_name;
