"FireCode Creator" is a program code generation software based on a variety of databases, which can quickly create data information: add, edit, view, list, search functions . By default, asp, aspx WEB programs, .net ordinary three-layer framework web programs, .net Windows programs, several code frameworks and multiple interface design templates are provided. The built-in .net code framework can create .net solutions in C# language and can be edited directly in VS2005. It can not only help .net beginners get started quickly, but also maximize the code writing efficiency of .net programmers.
Through the Fengyue code generator, we can generate the required program files based on the specified database in just a few steps:
1. Click "New Project File" and enter the project name, version, description, etc., which will become the remark information for the generated code file.
Specify the namespace, database connection, and save path in the "Data Settings" panel
Select the program framework to be generated: ASPX single-layer structure code framework. If you want to generate other types of programs, you only need to choose a different framework, such as asp or .net winform program.
Create a new virtual directory in IIS and set the "URL path" published by the program. Figure 1 Figure 2
2. After completing the project information settings, click "Generate Framework File" to copy the basic files in the specified framework to the folder where the project is saved. Figure 3
3. Select the data table and set the input control type and display type of different fields.
Set the control type of "User Name" to "Text Box", "User Password" to "Password Box", and "Photo" to "Upload File"
The input of country, province, and city can be set as a drop-down list to generate a multi-level linkage drop-down box. Associate the field to the corresponding data table, for example: the "Country" field in the user table, associate it with the data table that stores the "Country" data, and set the value fields for the displayed fields and options. Figure 4
Set the password field to "secondary input", with a minimum length of 6 characters. The generated code can verify whether the value entered again is consistent.
Set EMAIL to direct editing: check it. Then, on the list page, the direct setting function will appear. Figure 5
To set the control name encryption, you can set the prefix and suffix of the control name variable as needed, and check "Convert to Pinyin", so that the control name displayed in the HTML code will be the Chinese character based on the field title. Converted pinyin letters.
4. Set the language of the output interface. Currently, it supports the output of three versions: simplified Chinese, traditional Chinese, and English. Figure 6
5. After completing the settings, click the Generate Add, Search File and other buttons to output the required files. If you want to generate multiple files at one time, you can use the batch generation function. The system will output all the codes at one time based on the selected data tables and template files. Figure 7
6. Select a skin interface for the generated website. Any HTML file with added images can be set as the interface and called at any time. Figure 8

Setting session cookie parameters in PHP can be achieved through the session_set_cookie_params() function. 1) Use this function to set parameters, such as expiration time, path, domain name, security flag, etc.; 2) Call session_start() to make the parameters take effect; 3) Dynamically adjust parameters according to needs, such as user login status; 4) Pay attention to setting secure and httponly flags to improve security.

The main purpose of using sessions in PHP is to maintain the status of the user between different pages. 1) The session is started through the session_start() function, creating a unique session ID and storing it in the user cookie. 2) Session data is saved on the server, allowing data to be passed between different requests, such as login status and shopping cart content.

How to share a session between subdomains? Implemented by setting session cookies for common domain names. 1. Set the domain of the session cookie to .example.com on the server side. 2. Choose the appropriate session storage method, such as memory, database or distributed cache. 3. Pass the session ID through cookies, and the server retrieves and updates the session data based on the ID.

HTTPS significantly improves the security of sessions by encrypting data transmission, preventing man-in-the-middle attacks and providing authentication. 1) Encrypted data transmission: HTTPS uses SSL/TLS protocol to encrypt data to ensure that the data is not stolen or tampered during transmission. 2) Prevent man-in-the-middle attacks: Through the SSL/TLS handshake process, the client verifies the server certificate to ensure the connection legitimacy. 3) Provide authentication: HTTPS ensures that the connection is a legitimate server and protects data integrity and confidentiality.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.
