This article mainly shows you the "contest Analysis of PHP and ASP.NET", which is easy to understand and clear. I hope it can help you solve your doubts. Let the editor lead you to study and study this article "the contest Analysis of PHP and ASP.NET".

Both PHP and ASP.NET can build complex Web applications (such as e-commerce sites, Intranet, and enterprise portals), but there are several important differences between them. Unlike PHP, ASP.NET is not a language or parser, but rather a set of technologies in Microsoft .NET Framework for building Web applications and XML Web Service. Like PHP, Microsoft ASP.NET pages execute on the server and generate tags (such as HTML, WML, or XML) that are sent to desktop or mobile applications. The difference is that ASP.NET provides a powerful, object-oriented, and event-driven programming model for developing Web pages, while still retaining the simplicity that PHP developers are used to.

Compared to ASP.NET, PHP applications are based on a powerful object-oriented programming (OOP) pattern rather than a scripting pattern. This allows for more rigorous OOP functions, such as inheritance, encapsulation, and reflection. While most basic simple operations can be easily converted from PHP to ASP.NET, converting more complex applications is not that easy, which requires careful planning and consideration, and a more OOP-compliant approach.

This article assumes that the reader has experience in PHP and has a basic understanding of programming and software development. This article first briefly compares the differences between the basic architectures of the two in terms of code, briefly introduces the OOP development model, and then compares the functions of the two. * compares the syntax and common tasks when developing Web applications using PHP and ASP.NET.

Note: if you want to skip the details about the migration and just try to use ASP.NET, you can skip directly to the recommended follow-up section.

Comparison of PHP ASP.NET Architecture

After reading this article, by comparing grammar and language, you will understand that PHP and ASP.NET are very similar, and they have similar functions and syntax. However, from a more basic architectural level, PHP and ASP.NET are very different. PHP is based on a platform-independent processor / engine that parses PHP scripts, provides database connections, conforms to the Internet protocol, and provides many other tasks common to most Web application platforms.

ASP.NET is a framework built on a range of technologies, such as CLR, that provides a large number of well-organized class libraries that meet the needs of most of the functions to be used in Web applications. You can also easily create various components to extend the framework.

Although PHP provides similar functionality (such as PEAR libraries), PHP and ASP.NET are not exactly the same, because the ASP.NET framework is built entirely on OOP schemas and OOP concepts, while PHP is not. This difference is evident in the way classes and objects are accessed in PHP and ASP.NET.

Object-oriented programming in PHP ASP.NET

Although both PHP and ASP.NET provide the OOP pattern for application development, their support for various OOP concepts, such as encapsulation and polymorphism, is different. For example, PHP supports only partial encapsulation (for example, the declaration of methods and fields in a class) and partial polymorphism (no overloading and abstraction). In addition, because there are no concepts such as private, public, or protected functions and overloads in PHP's classes, PHP does not support these concepts and their access. OOP purists might say that ASP.NET and various languages do not fully support all the concepts in the OOP schema, and this is true for most languages that use OOP, such as C++ and Java.

This has both a positive side and a negative side. The downside is that for some Web developers, learning ASP.NET is more difficult than learning PHP, because PHP provides the scripting pattern that developers use when creating Web sites. However, developers who have used the OOP language and / or V will find ASP.NET more friendly and easy to learn.

The positive side of ASP.NET 's support for the OOP concept is that most parts of ASP.NET applications are well designed and can clearly separate content, logic, and data, so it is usually easier to support them from a long-term perspective of the application life cycle. In addition, because ASP.NET itself supports enterprise technologies such as message queuing, transactions (see the .NET Framework System.EnterpriseServices class), SNMP, and Web services, powerful applications with high scalability can be easily developed.

For an overview of the main concepts of object-oriented programming (from a Visual Basic perspective), see Object-Oriented Programming in Visual Basic.

PHP ASP.NET compilation

PHP

When a PHP page is requested, the HTML and inline PHP scripts are compiled to Zend Opcode (the Zend action code). Opcode is a low-level binary instruction that is the code actually used to provide PHP pages. After compilation, the Zend engine runs Opcode (similar to Java's runtime engine running bytecode), and then generates HTML and provides it to the client.

There are many commercial products that can be used to speed up the execution of PHP pages by optimizing these Opcode. Other ways to improve the performance of PHP scripts include caching Opcode and generated HTML.

ASP.NET

When a request for an .aspx page (or any other extension supported by ASP.NET) is made to IIS (Internet Information Services) or another Web server, the request is passed to ASP.NET for processing. If the page is requested * times, ASP.NET compiles it to MSIL (Microsoft Intermediate language). CLR (the common language runtime) then converts this MSIL code into machine code. Run the request using this compiled code. Subsequent requests will be run using the same machine code (assuming the page has not been modified).

It is important to note that because the binaries generated by CLR have been optimized to a limited extent, there is no need to use other products to help improve performance.

Also note that everything in ASP.NET is compiled into machine code before running. Even HTML text is converted to a string constant control and inserted into the control tree in the appropriate order.
