Seven reasons why php (as the mainstream development language) is better than ASP

ASP is a technology that Microsoft implements dynamic web pages. ASP supports some scripting languages, mainly VBScripp. Compared with ASP, you can also choose another open-source programming language-php (as the mainstream development language) and php (as the mainstream development language) it can run on multiple operating systems, including Linux and windows.

Although ASP is a good technology, I believe in the long term that php (as the mainstream development language) will play an extraordinary role in the future technical fields.

I think there are seven reasons why php (as a mainstream development language) is better than ASP:

1. Speed, speed, and speed

When I ran the php script for the first time (as the current mainstream development language), I couldn't help but say to myself, "it's too fast ", at that time, I was running my program on a 16 6 MHz machine, but it was still very fast.

ASP is never as fast as php (as the current mainstream development language), because ASP is built on the COM architecture. When using VBScript to write an ASP script, actually COM objects are used. when sending information to a user's browser, it uses the write method of the Response object, when it accesses the database and file system, it uses other COM objects. The use of these COM objects reduces the running speed.

In php (as the current mainstream development language) code, all work is run in the memory space of php (as the current mainstream development language, that is to say, php (as the mainstream development language) is not based on COM objects, so it runs faster.

The following figure shows the execution time statistics of a query statement on mssql (a powerful database platform on WINDOWS) that runs for 40 times:

Php (as the mainstream development language) Querying mssql (WINDOWS powerful database platform) 7 time (seconds)

Extension 01.88

ODBC extension 09.54

ODBC via COM (ADO) 17.28

Use OLEDB via COM 06.19

When we use php (as the mainstream development language ). it took 9.54 seconds to access the database using ODBC, and the time used to connect to the database using the COM interface was 80% higher than that used by php (as the mainstream development language.

OLEDB is Microsoft's high-speed database access technology, which is faster than ODBC. However, when we tested the efficiency of php (as the current mainstream development language) and OLEDB, the result was that php (as the current mainstream development language) had a 200% higher overall performance than OLEDB, in this way, we can get a faster execution speed without using COM.

Of course, php (as the mainstream development language) is not the fastest to execute, but we have just started and will gradually improve it, moreover, php (as the mainstream development language) is an open-source programming language. many programmers in the world are constantly improving its technology, I believe that it will certainly get a higher execution speed than the non-open source code system.

2. Advanced Memory management

Under iis (Microsoft's WEB server platform) 4, an ASP script header. asp. if it is contained by 20 pages, these 20 headers are retained in the memory during running. this problem is solved by iis (Microsoft's WEB server platform) 5, but only windows2000 supports iis (Microsoft's WEB server platform) 5, due to the incompatibility of iis (Microsoft's WEB server platform) 5, many servers still need to use low-level memory management under iis (Microsoft's WEB server platform) 4.

This problem does not exist in php (as the mainstream development language). an include file is called only when require is used.

3. no worries

One thing I hate very much is to buy an uneasy product. for example, if you buy a car, but the engine is bad, you need to replace it; when you buy a house, you need to repair the roof that leaks.

The ASP old products are the same. after you buy ASP, if you need encryption technology, you need to buy ASPEncrypt; when you need Email management, you need to buy ServerObjets Qmail; when you need to upload files, you need to buy Artisans SA-FileUp.

4. MySQL (the best combination with PHP) makes php (as the mainstream development language) more exciting.

The combination of php (as the mainstream development language) and MySQL (the best combination with PHP) is simple and wonderful. Php (as the mainstream development language) has many tools for managing and maintaining MySQL (the best combination with PHP), and the most comprehensive support for MySQk. Many useful functions, such as MySQL (the best combination with PHP) _ insert_id and MySQL (the best combination with PHP) _ affected_rows. other databases do not.

ASP and php (as the mainstream development language) are ideal solutions for medium-sized websites, but php (as the mainstream development language) close integration with MySQL (the best combination with PHP) makes php (as the mainstream development language) more advantageous.

MySQL (the best combination with PHP) is faster than Microsoft access (a favorite of small websites), and mssql (a powerful database platform on WINDOWS) it is faster than Oracle (a large-scale website database platform) (the best combination of MySQL and PHP), but the cost is high.

5. change Java and C ++ into a style

This advantage is just an opinion.

I know that you will not believe that a Visual Basic programmer will use php as the mainstream development language) with the programming style of Java and C ++, php is used (as the mainstream development language), but you will believe that many people still like Java and C ++, php (as the mainstream development language) is a language that is easy to learn with the programming style of these two languages.

Php (as the mainstream development language) supports structured programming. in VB, there are still few classes for its inheritance. The inheritance of php (as the mainstream development language) like Java and C ++ makes a large program full of class shadows everywhere.
