Compare the advantages and disadvantages of ASP, Asp.net, JSP, and PHP

ASP advantages:
1. No compilation required
2. Easy to generate
3. Independent from browsers
4. Object-oriented
5. compatible with any ActiveX Scripting Language
6. SourceProgramNo code Leakage

Disadvantages:
1. All windows problems will be fixed and accumulated. Security, stability, and cross-platform performance are all presented by binding with NT.
2. asp is very powerful because of the use of COM components. However, the original design of the Windows NT system causes a lot of security problems. As long as you do not pay attention to such components or operations, which of the following external attacks can gain high permissions, leading to website paralysis or data loss.
3. Because ASP is still a script language that does not use a large number of components, there is no way to improve its work efficiency. It must face the time test of real-time coding and coding, and we do not know what the components behind it will be like.
4. Cross-OS applications cannot be implemented. Of course, this is also one of Microsoft's reasons. Only in this way can we make full use of ASP's best capabilities. However, I think it is windows that limits ASP. The concept of ASP is designed to make the system run in a large variety of environments.
5. Some enterprise-level functions cannot be fully implemented: the entire cluster and load are horizontal.

Advantages of ASP. NET:
1. simple design and implementation.
2. Flexible language and support for complex object-oriented features.
3. Development Environment.

Disadvantages:
1. The database connection is complex.

JSP advantages:
1. One write task runs everywhere.
2. The system supports multiple platforms.
3. Powerful scalability.
4. diversified and powerful development tool support.

Disadvantages:
1. Just like ASP, some advantages of Java are just a fatal issue.
2. Lack of systematic information.
3. Ultra-slow speed

PHP advantages:
1. A development language capable of fast learning, cross-platform, and good database interaction.
2. easy to learn and use.
3. Work closely with Apache and other extension libraries.
4. good security.

Disadvantages:
1. Significant changes in database support.
2. Not suitable for large-scale e-commerce sites
3. Complicated installation.
4. Lack of formal business support.
5. Commercial applications cannot be developed.
