What are the similarities and differences between PHP and JSP?

PHP and JSP are both web development technologies, so what are the similarities and differences between PHP and JSP? The following article will give you a comparison of PHP and JSP, so that you can understand the similarities and differences between PHP and JSP. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

PHP is a server scripting language that is designed for web development and is interpreted and executed. It borrows a lot of syntax from C and Perl languages and has a simple and easy-to-use function. Features, so anyone who has learned C language can quickly become familiar with PHP development.

JSP is a server-side programming technology that helps in creating dynamic web pages. It uses Java language as the scripting language and combines it with HTML syntax; people who are familiar with JAVA language and HTML syntax can get started quickly.

But Java requires not only learning syntax, but also being familiar with some core class libraries, and understanding and mastering object-oriented knowledge. Java is more difficult to learn than PHP, so JSP technology is more difficult to master than PHP.

1. Comparison of database access between php and jsp

jsp uses Java language to access the database through JDBC, and can be easily accessed through database drivers provided by different database vendors database. The interface for accessing the database is relatively unified.

PHP uses different database access interfaces for different databases, so the database access code is not very versatile. For example: a web application developed in Java only needs very few modifications to be transferred from a MySQL database to an Oracle database. PHP requires a lot of modification work.

2. Performance comparison between php and jsp

1). JSP is based on the Java programming language, so it supports a lot of APIs and supports a lot of web development. third-party library. ; PHP has limited access to APIs and supports relatively few third-party libraries.

2), JSP supports object caching, but PHP does not support caching.

3), JSP is an abstraction of Java classes, so it can be garbage collected; while PHP does not support garbage collection.

4), JSP is very good at maintaining user sessions, while PHP will destroy the user's session every time.

5), JSP execution takes more time because it is converted into Servlet, compiled and executed; while PHP execution takes less time than JSP, with reduced coding and rapid development and execution, instant feedback and higher productivity.

3. Comparison of the system design architecture of php and jsp

jsp uses Java web development technology and needs to use object-oriented system design methods, while PHP still Adopt a process-oriented development approach. Therefore, a lot of system analysis and design work needs to be done in the early stage of development using Java.

4. Comparison of the cross-platform nature of php and jsp

Both Java and PHP have good cross-platform features. Almost all of them can run on different operating systems such as Linux or Windows without any modifications.

5. Comparison of the development costs of php and jsp

The most classic combination of PHP is: PHP MySQL Apache. It is very suitable for developing small and medium-sized web applications, and the development speed is relatively fast. And all software is open source and free, which can reduce investment.

JSP has a relatively long learning cycle and development cycle, and not all required software is free, and the development cost is relatively high.
