quot网站源码是什么意思
网站源码，我们可以把它理成源文代码，源码就拿我们当前看到的网站这个网页来说吧，其实它是源码php缓存源码由一大堆的源代码组成，通过我们的网站IE（Microsoft Internet Explorer）浏览器（或服务器）翻译成现在我们所看到的这个样子。网站源码也分为两种，源码一种是网站动态源码如：ASP，PHP，源码JSP，网站.NET，源码CGI等，网站速度趋势线源码一种是源码静态源码如：HTML等。什么是网站动态源码呢？最大的特点就是能够和用户之间互动。比如说网易的源码信箱，张三登陆的网站时候，会看到欢迎光临张三，溆浦老牌源码下载李四又登陆了，李四又看到欢迎光临李四，其实他们两个人登陆的是一个页面，这个就是动态源码的好处，如果要是财务系统源码 java用静态源码，好么网易有几百万的邮箱用户，每个人做一个页面那要多少页啊？动态源码不单单只有这么一点用处，比如说我们常见的一些论坛、留言本、计数器、pig开源框架源码聊天室等，都是由动态源码开发的。什么是静态源码呢，比如说我们当前看到的这个网页他就是静态的源码，静态源码无法实现以上的那些功能。现在有不少源码下载站，提供别人开发好的源码让我们下载。他们开发的都不错，美工也相当不错，基本上下载下来，只要稍加改动就可以使用了，更方便了我们建站，您可以跟据自己所需去下载，更重要的是，要先看看您自己使用的网站空间，是那一种的，比如说您使用的是ASP空间，那么您一定要下载ASP源码，不然下载别的是不能运行的。。
