What is the difference between ASP and PHP?

The difference between ASP and PHP: 1. PHP runs faster than ASP because ASP is built on the COM architecture; 2. There are differences in advanced memory management; 3. PHP has the best support for MySQk Comprehensive, the close integration of PHP and MySQL makes PHP more superior; 4. PHP has Java and C programming.

PHP is the abbreviation of the English hypertext preprocessing language Hypertext Preprocessor .PHP is an HTML embedded language. It is a scripting language embedded in HTML documents that is executed on the server side. The style of the language is similar to C language and is widely used.

ASP is the abbreviation of Active Server Page, which means "dynamic server page". ASP is an application developed by Microsoft to replace CGI script programs. It can interact with databases and other programs and is a simple and convenient programming tool. The format of ASP web page files is .asp, which is now commonly used in various dynamic websites. In addition, the abbreviations of aspirin, aspartic acid, Alibaba Software Sales Partner, and American Armed Systems and Programs Company are also ASP.

PHP is a technical language for writing websites, and ASP is also a language for writing websites.

So what is the difference between ASP website and PHP website?

1. Difference in speed

When I ran the PHP script for the first time, I couldn't help but said to myself: "It's too fast". At that time, I was operating at 166MHZ My program is running on a different machine, but it still runs very fast. ASP will never be as fast as PHP because ASP is built on the COM architecture.

When writing ASP scripts with VBScript, it actually uses COM objects. When sending information to the user's browser, it uses the write method of the Response object. When it accesses the database and file system , which uses other COM objects. The use of these COM objects slows down the running speed. In PHP code, all work runs in PHP's memory space, which means that PHP is not based on COM objects, so its running speed will be faster.

2. Differences in advanced memory management

Under IIS4, if an ASP script header.asp is included in 20 pages, then when it is run, it will be in the memory Keep the compiled copies of these 20 header.asp. IIS5 solves this problem, but only Windows 2000 supports IIS5. Due to the incompatibility of IIS5, many ** still have to use the low-level memory management under IIS4.

In PHP, this problem does not exist. Only when required will a certain include file be called

3. MySQL makes PHP more exciting

The combination of PHP and MySQL is simple and exciting. PHP has many tools for managing and maintaining MySQL, and its support for MySQk is the most comprehensive. Many useful functions such as mysql_insert_id and mysql_affected_rows are not available in other databases.

ASP and PHP are both ideal solutions for medium-sized websites, but the close integration of PHP with MySQL makes PHP even more superior. MySQL is faster than Microsoft Access, and Mssql and Oracle are faster than MySQL, but the cost is higher.

4. No worries. One thing I hate very much is buying a product that you are not sure about. For example, when you buy a car, but because the engine is broken, you need to replace it. Him; When you buy a house, you have to fix the leaky roof. Then ASP is like these products. When you buy ASP, if you need encryption technology, you have to buy ASPEncrypt; when you need email management, you have to buy ServerObjets Qmail; when you need file upload, you have to buy Artisans SA-FileUp.

5. Bug handling Have you ever asked Microsoft to modify some bugs in ASP? If you are not an organization like Boeing and you cannot get quick and appropriate modifications, what should you do when you encounter this? When a bug stops working, if the bug is not corrected, you will not be able to continue your work. In PHP, when you find a bug, you can modify it. If you are not an expert, you can ask an expert to modify it, and your modification will be accepted and recognized by the open code organization.

6. The programming style of Java and C

This advantage is just an opinion. I know you won't believe that a Visual Basic programmer would switch to PHP because it has Java and C programming styles, but you will believe that there are many people who still prefer Java and C, and PHP is a programming style with both languages. style easier to learn language. PHP supports structured programming, while VB uses fewer classes because of its inheritance. PHP's inheritance like Java and C makes a large program full of shadows of classes.
