先培养对php的兴趣,就先了解php相对其他程序的优点.其实优点很多了.主要列举以下几点.
php能做任何事情,例如收集表单数据，生成动态网页，或者发送／接收 Cookies。但 PHP 的功能远不局限于此。

asp---------
1.微软平台,花钱买.
2.漏洞多.非开源,很多代码运行环境用法具体内容不公布.
3.效能差.服务器系统.
4.程式传写不结构化.
5.除错不容易.错误不好修改.
6.组件支持复杂多.
jsp---------
1.对硬件要求高.
2.要有java基础.
3.除错不容易.错误不好修改.
4.号称执行速度最快的.(通过编译加速,php也可以)
5.大型企业的商业模式较适合.(银行,企业.)
php---------
1.跨平台(microsoft,linux,unix)、跨web server(IIS，apache)
2.结构化(类似C)、除错容易.
3.效能机佳.
4.对硬体要求低.
5.源码公开、漏洞少、风险低.
6.支持的数据库广泛.

Adabas D InterBase PostgreSQL dBase FrontBase SQLite Empress mSQL Solid
FilePro（只读） Direct MS-SQL Sybase Hyperwave MySQL Velocis IBM DB2 ODBC Unix dbm
Informix Oracle（OCI7 和 OCI8） Ingres Ovrimos

其他:bbs、留言版、杂志、文章、架站机.甚至可以.....写命令列程式.写图形使用者界面.最重要不要钱。
php大概运行的环境:
服务器环境:apache+mysql+php+phpmyadmin 有个软件叫appserv.exe的集成这些.
使用的编写工具:Macromedia Dreamweaver 或 EmEditor等.

大概了解下php写的基本方式,PHP 的 echo() 语句显示了,大概4种写法：

最常见获取系统信息的

再写个自己初学测试的:

    echo"买虚拟主机找坏狼！www.winshell.cn" //这里是php要写内容!
   ?>


基本先学这些了....主要的内容在以后呢....
