一 php与XML、XSLT、Mysql的结合运用,安装篇
    经常看到有用户问一些关于php与XML、数据库结合运用的贴子,也经常看到一些初学者
    把php代码与HTML代码混写到一起,然后在出错的时候找不到错误,急得团团转,下面我就给大
    家讲一下如何用XML技术将HTML代码和PHP程序分离,当然,分离的技术有好多种,比如PEAR中
    的IT模板.
    总的来说,个人认为使用XML技术是最方便的,废话不多说了,我们言归正传,
    讲一下在win2000下的安装

    使用php中的xml与xslt要用到一些dll库,
    extension=php_domxml.dll   //操作XML的函数库
    extension=php_iconv.dll    //转码用的,比如将GB2312的转成UTF-8的
    extension=php_xslt.dll     //XSLT的函数库
    
    使用上面这三个库的时候,你要将php安装目录下的dlls目录加入到路径中,否则会找不到
    这些类库的
    
    在下面的课程中,我们会用到php中的PEAR类库,主要用了DB类库,Sql2XML类库,大家可以在
    pear.php.net上下载最新的版本
    下载完上面二个类库以后,大家最好在php.ini中设置一下
    include_path = ".;d:\php\pear"
    
    d:\php\pear  是我的pear的安装路径
    
    设置完以后,重新启动一下机器,否则因为路径找不到而导致Apache启动不正常,无法正常使用
    
    
    至此要使用PHP中的XML和XSLT的设置就完成了,是不是很简单:)
    使用Linux的用户可以到
    http://www.gingerall.com/下载关于XSLt的源码
    http://www.gnu.org/software/libiconv/下载关于Iconv的源码
    
二  php与XML、XSLT、Mysql的结合运用,初级篇
    下面我要讲的是一个简单的从数据库中抽取数据,生成XML文档,使用XSLT转换成HTML的过程,
    该过程只讲使用这一技术的过程,不会涉及分页等其它的技术
    
    该示例我使用下面的数据库表及数据
    表名:企业用户信息表,英文名:yhxx
    表结构:
    #
    # 数据表的结构 `yhxx`
    #
    
    CREATE TABLE yhxx (
      nsrnm varchar(15) NOT NULL default '',
      qymc varchar(200) NOT NULL default '',
      qydh varchar(50) NOT NULL default '',
      PRIMARY KEY  (nsrnm)
    ) TYPE=MyISAM COMMENT='用户信息表';
    
    #
    # 数据表内容 `yhxx`
    #
    
    INSERT INTO yhxx VALUES ('310109040111985', '乔家饮食发展有限公司', '8621-63346626');
    INSERT INTO yhxx VALUES ('310104040221736', '上海嘉陵贸易有限公司', '74292546');
    INSERT INTO yhxx VALUES ('310108040331576', '翡翠艺术公司', '54861465');
    
    
    接下来我开始写抽取数据的程序与显示数据的页面
    为了使大家都能明白,我使用最简单的方法来写程序
    
    程序文件名称:browesData.php
    页面文件名称:browesData.html
    程序及页面文件提供下载,本程序已经在win2000、mysql下通过测试
    代码见下一页


如果大家对此技术感兴趣,我再为大家讲一下php与xml、xslt、数据库结合更深一步的应用

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
