This article mainly introduces what is the difference between jsp asp php, the text is very detailed, has a certain reference value, interested friends must read!

ASP PHP is a cross-platform server-side embedded scripting language, and JSP is similar to PHP; ASP can only be executed on Microsoft's server product IIS, while the other two can be executed on almost all platforms.

ASP

ASP adopts VBScript (JavaScript) as its own development language. ASP is a dynamic web language developed by Microsoft, which inherits the consistent tradition of Microsoft products and can only be executed on Microsoft's server product IIS (Internet Information Server).

ASP is a Web server-side development environment that can generate and execute dynamic, interactive, and efficient Web service applications. Its technical characteristics mainly include the following aspects:

Browser Independence: Clients can browse web pages designed by Active Server Pages by using browsers that execute HTML code. The scripting languages used by Active Server Pages (VBScript, JScript) are executed on the Web server side, and the client browser does not need to execute these scripting languages.

Active Server Pages is compatible with any ActiveX Scripting language. In addition to VBScript or JScript language design, you can also plug-in mode, using other scripting languages provided by third parties, such as REXX, Perl, Tel, etc. Script engines are COM (Component Object Model) objects that process script programs.

Using VBScript, JScript and other simple script languages, combined with HTML code, you can quickly write website applications. Server-side scripts can be used to generate client-side scripts.

Using ordinary text editors, such as Windows Notepad, you can program without compiling, easy to write, and can be executed directly on the server side.

PHP

PHP is a cross-platform server-side embedded scripting language. It borrows syntax from C, Java, and Perl, and combines PHP's own features to enable Web developers to write dynamic pages quickly. PHP is characterized by: support for the vast majority of databases, and its source code is completely open.

PHP can run normally on Windows, Unix, Linux Web servers, and also supports IIS, Apache, and other general Web servers. When users change platforms, there is no need to change PHP code.

PHP and MySQL are the perfect combination right now. Users can also write their own peripheral functions to access databases indirectly, in such a way that they can easily modify the code to accommodate changes in the database they are using.

Tip:

PHP LIB is the most commonly used set of base libraries that can provide general business needs. But PHP provides database interface support that is not uniform enough.

JSP

JSP is similar to PHP and can be executed on almost all platforms, such as Windows, Linux, Unix. Apache, a Web server, already supports JSP, and Apache is widely used on Windows, Unix, and Linux, so JSP has a wider range of execution platforms.

Although Windows now has a large market share, Unix still has a big advantage in servers, and the new Linux is coming.

JSPs and JavaBeans don't even have to be recompiled when ported from one platform to another because Java bytecode is standard and platform-independent. ASP, PHP and JSP are all Web server-oriented technologies, and client browsers do not require any additional software support.

Normal HTML pages rely solely on Web servers, but ASP, PHP, and JSP pages require additional language engines to parse and execute program code. The results of the execution of the program code are re-embedded in HTML code and sent to the browser together. All three provide the ability to mix some kind of program code in HTML code and have it interpreted and executed by the language engine. JSP code is compiled into servlets and interpreted and executed by the Java Virtual Machine, and this compilation occurs only on the first request for a JSP page.

In ASP, PHP, JSP environment, HTML code is mainly responsible for describing the display style of information, and program code is used to describe the processing logic.
