Answer 1: Programming languages ​​are generally used to write applications, such as C, C++, VB, DEPHI, JAVA, etc., which are powerful and difficult to learn.
Scripting languages ​​are generally used to write some simple applications, such as JS, VBS, JSP, ASP, PHP, etc. Macro programs can also be regarded as scripting languages. The biggest disadvantage of scripting languages ​​compared to programming languages ​​is their low execution efficiency, but they are easier to write.
HTML is not a language. Although it is called Hypertext Markup Language, in fact it can only be regarded as some control tags, and what is written is not called a program.
Static There can also be VBS or JS scripts in web pages, they are just foreground.
You can use either VBS or JS in ASP, but usually most people use VBS, they are background.
PHP has almost the same syntax as C. In fact, it is almost the same as JS. They are very close.
If you want to make a website, you need to learn ASP (a little behind, but it is easier to get started) or PHP or JSP or ASP. net (you can learn VB.net or C#.net) at least the same.
The free whole-site system can be used and modified for free, but most of them are not allowed for commercial use. You can go to the corresponding official website to view the authorization file.

Answer 2: c;c++;perl;vb;assembly, etc. These are programming languages
Scripting language is mainly our common asp ;php, etc.
asp is subordinate to vb and is a subset of vb
php is developed using c
Both asp and php require server parsing and execution, but html is different from them, html It does not require server parsing and execution, it only needs to be output directly, so we call html hypertext. It's better to learn PHP so that you can rewrite the core of the website building system, but if you only use it to make ordinary corporate websites, it doesn't matter whether you learn PHP or not.
