This article mainly introduces PHP and ASP.NET what the difference, has a certain reference value, interested friends can refer to, I hope you read this article after a lot of gains, the following let Xiaobian with everyone to understand.

1. Extensibility and maintainability

Whether you choose PHP or ASP.NET, there is no impact on extensibility or maintainability. Extensibility and maintainability of Web applications depend on several aspects:

Programmer's Experience

Use best coding practices

Use reliable programming frameworks

Follow programming guidelines and standards

2. performance and speed

There have been many arguments about this, and most of them are not objective and one-sided. These arguments don't really inform us, they just extol one language and belittle another.

When it comes to measuring the speed of Web applications, there are many factors worth considering. So that the speed of the programming language has little impact on the speed and performance of most current websites.

However, if this language is to accomplish the huge tasks that sites like Yahoo or Google perform every day, it is necessary to choose a programming language that can perform large tasks quickly, which is why Google and Yahoo choose multiple programming languages (mostly open source), each designed to perform the tasks best suited to it.

Below, I analyze various common and uncommon scenarios and explain which tasks are better.

The first common scenario

A common task for Web applications is to access and query databases, and output the results to Web servers and browsers. Therefore, in this common scenario, all programming languages are expected to act as communication or interfaces between database servers and Web servers. In this scenario, the speed of the programming language has little impact on the overall process; the speed of the process depends primarily on the database server, Web server, client Web browser, and bandwidth.

If you consider the popular mainstream database servers, MySQL (now Oracle), PostgreSQL, MSSQL, and Oracle are all struggling to improve speed and performance. We see that each version of the database server upgrade brings new features and better performance, so I think any of the above database servers will perform very well as long as the database programmer uses optimized and practical SQL queries and, if necessary, uses advanced features such as caching.

Google, Facebook, YouTube, Yahoo and FIFA, which recently gained huge audiences for the World Cup, are all using MYSQL. Therefore, the ability of MySQL database server is beyond doubt.

Based on online surveys, as of press time, communication and interface speeds between PHP and MySQL are faster than ASP.NET and MSSQL, but not significantly.

The second common scenario

Another common task for Web programs is to access the file system, find an image, and send it to a Web server. In this case, the task of programming languages remains minimal, and the burden of communicating with programming languages falls primarily on the operating system and file system.

Based on online statistical surveys, Linux operating systems and EXT4 (file system) outperformed Windows operating systems and NTFS (file system) at press time.

The third common situation

Most Linux / Unix servers run sparingly, without any extra non-essential packages or GUI interfaces, so these operating systems use very little CPU and RAM, leaving more resources for databases and Web servers.

Most Windows servers run unwieldy, with many redundant packages that consume a lot of CPU and RAM.

Obviously, LAMP has an advantage over ASP.NET because it has more resources available.

A fourth, less common condition

ASP.NET is usually written in C#. In general, C#is a faster programming language than PHP so far. (This may change, however, because programming languages are constantly updated for speed.) So, assuming that it takes 2,000,000 cycles to complete a calculation, an ASP.NET program written in C#will run faster than a PHP program. However, this is a very rare case where the number of cycles per calculation is at most several hundred instead of 2,000,000. Also, in this case, it is worth considering why a 2,000,000-cycle calculation should be done.

Other language-independent factors that affect performance include:

Programmer's knowledge and ability to write code

Programmer's knowledge reserve and ability when writing SQL query statements

Required functionality (some features take longer to execute on ASP.NET than PHP, and some just the opposite)

When it comes to performance, I have to talk about some professional application performance monitoring tools. It can effectively optimize code, SQL statements, etc., reducing the impact of code writing on performance and speed.

3. Cost

PHP, MySQL Server, PostgreSQL Server, Apache Server and Linux OS are free to use and upgrade. In addition, there is no additional license fee for having a backup host or running multiple servers to balance the load or set up a server cluster.

LAMP (Linux, Apache, MySQL and PHP) is also more popular among hosting companies. The popularity of LAMP hosting makes monthly hosting costs lower compared to Windows hosting.

ASP.NET and IIS are free if you buy Windows. Microsoft Windows Server, SQL Server and future updates are expensive. For example, Microsoft Server 2008 R2 64-bit standard edition costs around $1029, while Microsoft SQL Server 2008 for small businesses costs around $1038.

If the site becomes popular, it becomes necessary to have a backup host, or run multiple servers to Load Balancer, set up a server cluster, then the above costs will increase significantly.

4. support and resources

Since LAMP is open source, professional and friendly developers around the world have been providing continuous support for updates and improvements to the open source platform. In addition to this, PHP and LAMP platforms have a lot of other resource support and developer support.

I mention the word "friendly" because developers who contribute to the open source community do not do so for financial gain. If you run into a functional challenge and need help with coding, ask questions on PHP forums and you'll be sure to receive helpful information from friendly programmers.

ASP.NET relies more on improvements and updates made by Microsoft's limited number of developers. There are relatively few contributors who can help solve ASP.NET.

5. deployment time

ASP.NET requires a lot or more lines of code to complete complex features and functionality than PHP, and takes more time to develop.

Also, PHP is compiled on the server side, so when you change functionality, you can see the changes without extra steps. ASP.NET code, by contrast, needs to be compiled every time it is modified. ASP.NET takes more time to develop than PHP.

6. compilers and tools

PHP and MySQL both have independent compilers, and PHP developers have access to a much larger number of compilers.

Most ASP.NET programmers rely on Microsoft Visual Studio compilers to develop. NET programs. (Many ASP.NET programmers love and hate Microsoft Visual Studio)

This is a completely different style of programming-PHP programmers and open source developers prefer text editors such as VI, VIM, Notepad ++.

VI and VIM are very advanced independent editors. Once developers fully master the capabilities of these editors, they can do complex programming quickly, efficiently, and independently. As a result, they have more flexibility in controlling the code. When it comes to using or integrating with JavaScript, Ajax, JQuery, etc., PHP developers tend to have an advantage because they are familiar with open source environments and use VI or VIM to hand-type code.

7. platform independence

PHP is platform independent and can run on any platform in Linux, Unix, Mac OS X, Windows. ASP.NET runs only on Windows platforms.

8. What platforms do popular websites run on?

The table below lists the platforms and languages used by popular websites. Note: Please don't confuse C with C# (pronounced C Sharp) - they are completely different programming languages. ASP.net is mostly programmed in C# (C Sharp) or Visual Basic and not C.

Note: Do not confuse C with C#, they are two completely different programming languages. ASP.NET is usually programmed in C#or Visual Basic, not C.

9. prevalence

LAMP is more popular than Windows. Based on Netcraft's July 2010 survey of 205,714,253 Web servers, 112,945,968 (54.90%) Web servers are hosted on Apache, 53,217,620 (25.87%) Web servers are hosted on Windows, and the rest are hosted on other platforms.

10. Availability and ease of deployment

The unfriendliness of Linux has long been misrepresented.

In practice, this depends on the user's platform building experience and knowledge reserve.

But I have to say that I was impressed by the improved Linux distributions that are popular these days. Distributions such as Ubuntu, Red Hat, CentOS, openSUSE, and Fedora are not only easy to install and deploy, but also provide a simple and straightforward GUI interface that makes configuring Linux servers easier.

Unfortunately, in my opinion, Microsoft's servers are declining in usability, server management is getting clumsy, and they are full of unnecessary features.

Thank you for reading this article carefully. I hope that Xiaobian's "What are the differences between PHP and ASP.NET" article will be helpful to everyone. At the same time, I hope that everyone will support it a lot. Pay attention to the industry information channel. More relevant knowledge is waiting for you to learn!
