php菜鸟的基础有关问题
php初学者的基础问题
小弟初学PHP,以前是一直做asp.net的,现在对PHP的语法有了大概的了解,也下载了别人的代码模板参考,想请问各位两个问题
1.入下图1所示,PHP的代码是和HTML混合起来编写的,请问能不能分开编写?html归html代码,PHP代码归PHP代码这样,两种代码合在一起编写感觉很乱也不利于维护啊
2.如图2所示,在body中有两段PHP代码,那么当页面加载的时候是运行那一段代码?还是两段都运行?先运行哪一段?如果同一个页面中有两个按钮,实现不同的功能,那么如何实现点击按钮1,执行一段PHP代码(例如方法A)?点击按钮2,执行一段PHP代码(例如方法B)?
希望各位高手帮忙解答下

------解决方案--------------------
1、asp.net 可以代码分离吗?我只知道 C# 用伴随文件实现代码分离
php 需要引入模板引擎类实现代码分离
2、你不是有编程基础的吗,难道代码被条件语句分割都看不出来吗?
既然代码在条件分支中,自然就是有条件执行啦
------解决方案--------------------
用框架 如thinkphp,或者模板 如:smarty 可以实现php与html分离
php文件是从上往下的顺序执行的。
------解决方案--------------------
搜索 php MVC
视图 与 逻辑和数据分离才行!
