The role of PHP technology application in website development_PHP tutorial

1. Introduction

An automatic web page generation tool developed using PHP technology application, which can not only be used as a self-service website builder The platform can also be used as a website management system. Its data updates can largely meet the user's "personalized needs", that is, the content and style are close to what the user wants. The system is completely graphic and visual, even if you don't know the expertise in making web pages or the HTML language , by setting parameters in the system such as columns, template settings, website keywords, functional modules, etc., users can also use it to easily create ever-changing and colorful websites.

2. Main system development tools and related technologies used

(1) Introduction to system development tool PHP

PHP It is the abbreviation of Hypertext Preprocessor, which is hypertext preprocessing. PHP can be embedded in HTML, the language is simple and easy to master; it supports cross-platform and is easy to transplant; it can run under Linux, Unix or Windows operating systems, and supports popular web servers such as IIS and Apache; PHP source code is completely open and free; PHP has built-in database support and can access many mainstream databases, such as Oracle, MSSQL, Dbase, Sybase, Informix, MySQL, etc.; it has strong scalability. When the WEB server is under great demand, PHP performance remains stable and there will be no performance drop. situation; PHP has powerful text processing capabilities and supports POSIX extensions, Perl regular expressions and XML document parsing.

(2) Main technologies used in PHP technology applications

1. Template technology. Template technology is where developers pre-design some commonly used framework structures, classify pages according to functional types, summarize commonly used page types, and generate a template library. Users can import, export and manage website styles, which style should be used for the website, Just click to set it as the default website style, instead of re-building it yourself, which saves users development time and makes it easier for users to use.

2. Tag technology. The labeling of action functions can partially encapsulate the display function of the page in the page, making the entire page more concise and easy for users to call, code reuse, code maintenance and system expansion.

3. Main functions of the system using PHP technology

This system can generate static HTML files for all website content, which can greatly save host resources and improve system performance. , fully static processing technology is a necessary condition for building large-scale sites. Different users can choose different backend operation interfaces, and users can make their own backend interfaces and then add them to the backend interface management.

(1) Integrate website function modules. Some functional modules can set it in the background, but do not need it to actually appear on the page, but reference its function somewhere. This allows users to modify the functional module at will without affecting the settings. Page layout, which greatly reduces the cost of modifying functional modules.

(2) Powerful template function. The system not only provides built-in template tag calling, but also provides tag expansion functions. With this function, users can write their own functions and then add tags in the background to get template parsing. Generally used to display data outside the system, such as forum data, real-time display data for monitoring, etc. Users can dynamically change templates without changing website functions, which will bring great convenience to website developers and maintainers.

4. Backend operation of website construction in PHP technology application

(1) Website backend function module design

1 .User management: The user management module can define the user's permissions, the type of website owned by the user, bind the domain name of the user's website, set the usage time of the user's website, etc. Through the user management function, different levels of services can be provided to different levels of users, so that the user's website can achieve different functions.

2. Interface management: The interface management module can realize the addition, online editing, deletion, parameter setting, etc. of the interface. Through the interface management module, users can be provided with prepared templates, and templates can be assigned to users according to the needs of different users.

3. Picture management: Picture management is divided into system picture management and user picture management. System pictures can be used by all users, and user pictures are only for the user. Picture management can realize the adding, modifying and deleting operations of pictures. Through the image management module, you can control the space size of images uploaded by users, manage images of different users separately, and put images that can be used by most users into the same folder for unified management to save server space and review Images uploaded by users, and illegal or unhealthy user images can be forcibly deleted.

4. Database management: The main functions of the database management module include data backup, recovery, optimization, and upgrade. All websites built using automatic web page generation tools have their databases put into a unified large database. In this way, a lot of data can be used by multiple user websites, greatly saving database space, and each user can use it independently. Manage your own virtual database.

(2) Website management background function module design

1. Parameter system: mainly sets the parameters of the website. Such as the name of the column, the number of columns, the type of columns, etc., template settings, website name, website keywords, website language, hiding and displaying of functional modules, and modification of the top and bottom areas. The parameter setting system allows users to build the basic framework of a website in the shortest time. After parameter setting, it can be said that a website is basically formed.

2. Website module management system: mainly sets the functions of the website. For example, the order system is a very commonly used system on websites. If it is made into a ready-made system, the user only needs to enter some parameters to set up the order system. There is no need for the user to write a program or write a display style; the counter setting allows the user to choose the counter. There is no need to worry about the implementation details of the counter in terms of style and display position; the side module provides users with commonly used side functions, such as login system, site search system, log system, friendly links, etc.; the advertising management system is convenient for users to use on any page. Set up ads, choose ad styles, etc.; users can use the image rotator to switch multiple images based on time. The website module management system integrates the common functions of most websites, allowing users to build a powerful website just by typing without knowing any website production programming.

5. Conclusion

The automatic web page generation tool using PHP technology can not only be used as a self-service website building platform, but also can be used as a website management system. Through template customization, specially designed web page templates can be applied, so that the user's website not only has its own characteristics, but also has various dynamic management functions, so that non-professional technical personnel who can only enter text can quickly and efficiently complete their own web pages. , thereby realizing self-service construction, management and updating of websites, which will certainly greatly improve my country's information construction process.
