What does php mean?

PHP The full name is PHP Hypertext Preprocessor, which means "hypertext preprocessor". It is a cross-platform, open source, free, server-side scripting language, similar to C language, and is a commonly used website programming language.

PHP's unique syntax mixes C, Java, Perl and PHP's own syntax. It is conducive to learning and widely used. It is mainly suitable for the field of web development.

Compared with other programming languages, dynamic pages made with PHP embed the program into the HTML (an application under the standard universal markup language) document for execution, and the execution efficiency is higher than that of completely generating HTML tags. CGI is much higher; PHP can also execute compiled code. Compilation can achieve encryption and optimize code running, making the code run faster.

According to the requirements of dynamic websites, PHP language, as a language program, its specificity gradually appears in the application process, and its technical level will directly affect the operating efficiency of the website. Its characteristics are that it has an open source code and is highly similar to general-purpose languages ​​such as C language in terms of programming. Therefore, it is easy to understand and has strong operability during operation.

At the same time, the PHP language has a high level of data transmission processing and output, and can be widely used in Windows systems and various web servers. If the amount of data is large, the PHP language can also broaden the link surface and connect to various databases to alleviate the pressure of data storage, retrieval and maintenance.

With the development of technology, PHP language search engines can also tailor their services to implement personalized services, such as classifying, collecting and storing data according to customer preferences, which greatly improves the efficiency of data operation.

What does jsp mean

The full name of JSP is Java Server Pages, and its Chinese name is java server page. It is a dynamic web development technology . It uses JSP tags to insert Java code into HTML web pages; tags usually start with <% and end with %>.

JSP is deployed on the network server and can respond to requests sent by the client and dynamically generate Web pages of HTML, XML or other format documents based on the request content, and then return them to the requester. JSP technology uses Java language as a scripting language to provide services for users' HTTP requests, and can handle complex business requirements together with other Java programs on the server.

JSP embeds Java code and specific changes into static pages, using the static pages as templates to dynamically generate part of the content. JSP introduces XML tags called "JSP actions" to call built-in functions. Alternatively, you can create JSP tag libraries and then use them just like standard HTML or XML tags. Tag libraries enhance functionality and server performance without being limited by cross-platform issues. JSP files are converted into more primitive Servlet code by their compiler at runtime. The JSP compiler can compile the JSP file into a Servlet written in Java code, and then the Java compiler can compile it into binary machine code that can be executed quickly, or it can be directly compiled into binary code.
