Is PHP better than ASP?

Seven reasons why php is better than asp

ASP is a technology used by Microsoft to implement dynamic web pages. ASP supports some scripting languages, mainly VBScript. Compared with ASP, you can also choose another open source programming language - PHP. PHP can run on a variety of operating systems, including Linux and Windows.

Although ASP is a good technology, in the long run I believe that PHP will have extraordinary performance in the future technology field.

I think there are seven reasons why PHP is better than ASP:

1. Speed, speed, speed

When I ran the PHP script program for the first time, I couldn't help but said to myself: "It's too fast." At that time, I ran my program on a 166MHZ machine, but it still ran 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, it uses other COM object. 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.

The following is the execution time statistics of a query statement we ran 40 times in MSSQL7:

PHP Querying MSSQL7 time (seconds)

Using MSSQL extension 01.88

Using ODBC extension 09.54

Using ODBC via COM (ADO) 17.28

Using OLEDB via COM 06.19

When we use PHP.ODBC, accessing the database takes 9.54 seconds, and using the COM interface to connect to the database takes 80% longer than PHP.

OLEDB is a high-speed database access technology from Microsoft. It is faster than ODBC. But when we tested the efficiency of PHP and OLEDB, the result was that the overall performance of PHP was 200% higher than that of OLEDB. This leads us to the conclusion that faster execution speed can be achieved if COM is not used.

Of course, PHP's execution speed is not the fastest, but we have just started and we will gradually improve it. Moreover, PHP is an open source programming language. Many programmers in the world are constantly improving its technology. I believe He will definitely achieve higher execution speed than non-open source systems.

2. Advanced memory management

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

In PHP, this problem does not exist. Only when require is required, an include file will be called.

3. No worries

One of the things I hate very much is buying a product that you don’t trust. For example, when you buy a car, but because the engine is broken, you need to replace it; when you buy a house, you Going to fix the leaky roof.

Well, these products in ASP are the same. After 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 to upload files, you have to buy Artisans. SA-FileUp.

4. 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.

Both ASP and PHP are 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.

5. Java and C++ programming styles

This advantage is just an opinion.

I know you won't believe that a Visual Basic programmer would switch to PHP just because it has the programming styles of Java and C++, but you will believe that there are many people who still prefer Java and C++, and PHP is a programming language that has both Java and C++. Programming style easier to learn language.

PHP supports structured programming, but in VB there are still fewer classes because of its inheritance. PHP's inheritance like Java and C++ makes a large program full of shadows of classes.

6. Bug handling

Have you ever asked Microsoft to fix some bugs in ASP? If you are not an organization like Boeing, you cannot get quick and appropriate modifications. So when you encounter a bug and stop working, if the bug is not fixed, you You will not be able to continue your work.

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.

7. Transplantability

Microsoft often modifies ASP. The next version is called ASP+, and testing has begun. I believe they will fix many of the issues I have mentioned. But there is no doubt that Microsoft will limit you within the scope of their products.

I used to be a Mac programmer. When Windows 95 came out, I started to change, but many of the original codes could not run under Windows 95. These codes are now put aside. I am very sorry. So I don't want such a tragedy to happen again under windows.

Don't forget that Novell was once as popular as Microsoft's network operating system, but now not many people use it, so Microsoft will do the same.

I found PHP. I still work under windows, but I feel comforted knowing that PHP code can run on Solaris, Linux and many other operating systems.

The above has introduced whether PHP is better than ASP, including aspects of content. I hope it will be helpful to friends who are interested in PHP tutorials.
