asp ini mysql nbsp php

一、PHP简介

  PHP和ASP一样是运行在服务器端的脚本语言。它和ASP又很不相同:

 

PHP

ASP

运行环境

UNIX、Linux、Win98/NT等 Win98 PWS、NTW Peer Web Server、NTS IIS

语言风格

C语言 Basic语言

费用问题

免费使用,并发布源代码 要付费用

... ...

我认为,比ASP好

二、PHP安装

  将下载后的文件解压,到一个目录(比如:c:\php3)下,然后将php3.ini-dist文件copy到你的Window目录(比如:c:\windows),并且将文件改名为php3.ini。好了,先到这里,我们跳到下一节去安装apache。

 三、使php支持mysql

 在php3.ini文件中有如下行

  ;Windows Extensions
  ;extension=php3_mysql.dll

  您要做的就是将;extension=php3_mysql.dll的“;”去掉,使php支持mysql数据库。

 四、PHP的编辑格式

1.          ... ...   ?>  

2.

3.

   ... ...

 

4.

  但是,你如果要象用4这种形如ASP标记的方式做,你必须在php3.ini文件中,将

  asp_tags = Off

  改为:

  asp_tags = On
