HTML代码和PHP分离的疑问

看了一下 http://123langzheng.blog.163.com/blog/static/1362078062011125111528576/

以下举例子说明它们的用法，假设 IntegratedTemplate 类和 IntegratedTemplateExtension 类分别在 C:\php4\pear\HTML\ITX.php 和 C:\php4\pear\HTML\ITX.php 中。我们写的代码放在C:\TestPHP\PHP4\Welcome.htm 和 C:\TestPHP\HTML\Welcome.php 中。将C:\TestPHP\PHP4 在Web Server 上设成虚拟目录 /testphp 并且给与脚本执行权限，确认C:\TestPHP\HTML\Welcome.htm 无法通过远端浏览器访问。在 php.ini 里面设置 include_path = ".;C:\php4\pear"

我用的是 Zend Studio 10.0 ，php版本选的是5.4

假设 IntegratedTemplate 类和 IntegratedTemplateExtension 类分别在 C:\php4\pear\HTML\ITX.php 和 C:\php4\pear\HTML\ITX.php 中。

这个啥意思？为什么还要假设？还有 IntegratedTemplate 类和 IntegratedTemplateExtension 类在哪？
pear这文件夹是啥？

我看的教程是《PHP从入门到精通第二版》里面没有这方面内容啊？

难道说上面的说明已经相当充分了，只是我太笨看不懂？

回复讨论(解决方案)

1、pear 是 php 代码书写的一个类库，流行于 PHP4
由于 php5 引入了大量新特性，一些原来需要用代码书写的类，也定型并内置到 php 系统中了
所以现在去看基于 php4 的教程很是过时了
2、html 代码与 php 代码分离，统称为模板技术
比较专业的模板引擎是 Smarty 相比之下 IntegratedTemplate 和 IntegratedTemplateExtension 就是小儿科了
Smarty 也是用 php 代码写成的，使用时需引入
Smarty 4 已经进驻 Java，大有替代 Jstl 的趋势
3、当然，庞大的系统并不一定适合实际应用场合，所以开源的 php 项目大多都有自己的模板引擎
4、初入道还是先写混编代码比较好，这样有利于系统的学习结构化编程思想
深入后就会发现模板技术的优越，到时你也具备了自己写模板引擎的能力了
