The difference between asp.net and php: 1. ASP is a WEB server-side development environment, while PHP is a cross-platform server-side embedded scripting language; 2. ASP does not require compile compilation and is easy to write. It can be executed directly on the server side, and PHP can be compiled into functions that connect to many databases.

The difference between asp.net and php:

Which one is better, asp.net or php?

Before .net, Microsoft had ASP. With Microsoft's vigorous promotion, it still looks very promising. But now, Microsoft wants to promote asp.net, and ASP has become an obstacle. So starting from Windows Server 2003, Microsoft has imposed many restrictions on ASP, such as uploading files that cannot exceed 200KB.

Look now, what Microsoft has done to Windows XP in order to promote Windows Vista and the latest Windows 7, directly stopped technical support for ordinary users, just to force you to change. If in the future, Microsoft has something better than .net. Microsoft is expected to impose similar restrictions on .net and force users to upgrade.

PHP is completely open source, its needs are closer to daily applications, the code style is similar to C language, and it is easier to learn.

In terms of speed

Although PHP is not compiled, the execution efficiency of actual applications under Linux is definitely faster than .net under Windows. The runtime security of PHP is definitely higher than that of Microsoft's .net. But usually the code is not protected. Commercial Zend software is usually required for encryption. Of course, this encryption process is also a compilation process. While protecting the code, it also improves execution speed. The new Zend encryption algorithm has not yet been successfully cracked. However, if .net only does simple compilation, it will be easily decompiled back.

PHP currently has two branches, one is PHP4 and the other is PHP5. Both branches are under common maintenance. This ensures that systems that used PHP4 in the past can still ensure continued good security and feature updates.

Introduction

ASP's full name is Active Server Pages, which is a WEB server-side development environment that can be used to generate and run dynamic, interactive, high-performance WEB service application. ASP uses the scripting language VBScript (Java script) as its own development language.

PHP is a cross-platform server-side embedded scripting language. It borrows a lot of syntax from C, Java and Perl languages, and couples PHP's own features to enable WEB developers to quickly write dynamically generated pages. It supports most current databases. Another point is that PHP is completely free. You don’t need to spend money. You can download it freely from the PHP official website. And you have unrestricted access to the source code, and you can even add the features you need.

Technical Features

ASP:

1. Use VBScript, JScript and other simple and easy-to-understand scripting languages, combined with HTML code, you can quickly complete the website application.

2. No need to compile, easy to write, and can be executed directly on the server side.

3. Use an ordinary text editor, such as Windows Notepad, to edit and design.

4. It has nothing to do with browser (Browser Independence). As long as the client uses a browser that can execute HTML code, it can browse the web content designed by Active Server Pages. The script languages ​​(VBScript, Jscript) used by Active ServerPages are all executed on the WEB server side, and the client's browser does not need to be able to execute these script languages.

5.Active Server Pages is compatible with any ActiveX scripting language. In addition to using VB Script or JScript language to design, you can also use other script languages ​​provided by third parties through plug-in, such as REXX, Perl, Tcl, etc. The script engine is a COM (Component Object Model) object that handles script programs.

6. Server-side scripts can be used to generate client-side scripts.

7.ActiveX Server Components (ActiveX server components) have unlimited scalability.

8. You can use Visual Basic, Java, Visual C++, COBOL and other programming languages ​​to write the ActiveX Server Component you need.

PHP:

Database connection

1.PHP can be compiled to have functions that connect to many databases. PHP and MySQL are an excellent combination right now.

2. You can also write your own peripheral functions to access the database indirectly. In this way, when you change the database you use, you can easily change the encoding to adapt to such changes.

3.PHPLIB is the most commonly used series of base libraries that can provide general transaction needs.

4. However, the database interface support provided by PHP is not unified with each other. For example, the interfaces for Oracle, MySQL, and Sybase are different from each other. This is also a weakness of PHP.

PHP provides classes and objects. Web-based programming work requires object-oriented programming skills. PHP supports constructors, extracted classes, etc.
