PHP程序和ASP程序转换要注意的问题
有的程序有关电子商务的东西,还是自己动手比较保险。一做下来发现很多地方要注意。
1。语法
如果你对两种都很熟,就比较容易了,但是写着写着昏了头的事情经常发生,。大家知道现在web服务器的错误提示都糊里糊涂的。
php每句话最好加上分号,即使有的地方可以不加。注意各个段落加上注释,不同的循环(特别是嵌套)之类的之一层次。
2。变量
由于原来的程序不是我写的,所以对页面表单、session之类的东西特别注意了一下。如果前一个程序写的不太清楚,麻烦大一些。
php里面对变量大小写敏感,asp不敏感,所以最好先养成好的习惯,给变量取名字的时候尽量规范一些(自己的规范:-),asp中最好使用option explicit。
3。页面
将可能在不同页面出现的相同内容全部作成单独的页面,然后在需要的时候包含进去,修改起来方便。大家都知道客户的要求可能一天一个样。
4。最重要的就是function
