This article mainly explains "the specific role of PHP technology in website development". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "the specific role of PHP technology in website development"!

I. introduction

The automatic web page generation tool developed by the application of PHP technology can be used not only as a platform for self-help station construction, but also as a website management system. To a large extent, its data update can meet the "personalized needs" of users, that is, it is close to what users want in terms of content and style. the system is completely graphic visual, even if it does not know the special technology of making web pages and does not understand HTML language. Through setting parameters in the system, such as columns, template settings, website keywords, function modules and so on. Users can also use it to easily create ever-changing and colorful websites.

Second, the main development tools and related technologies of the system

(1) A brief introduction to the system development tool PHP

PHP is short for Hypertext Preprocessor, that is, hypertext preprocessing. PHP can be embedded in HTML, the language is simple, easy to master; cross-platform support, easy to transplant, can run under Linux, Unix or Windows operating systems, support IIS, Apache and other popular Web servers; PHP source code is completely open and free; PHP built-in database support, can access many mainstream databases, such as Oracle, MSSQL, Dbase, Sybase, Informix, MySQL, etc. Strong scalability, when the WEB server bears great demand, PHP performance is still stable, there will not be a sudden drop in performance; PHP has a powerful text processing function, supporting POSIX extension, Perl regular expression and XML document parsing.

(2) main technologies used in the application of PHP technology

1. Template technology. Template technology is that developers design some commonly used framework structures in advance, classify pages according to functional types, sum up commonly used page types, and generate template libraries, so that users can import, export and manage the website style. which style the website uses, you only need to click to set it as the default website style, instead of re-building it yourself, which saves users' development time and facilitates the use of users.

two。 Label technology. The tagging of the action function can partly encapsulate the display function of the page, making the whole page more concise, and it is also easy for users to call, code reuse, code maintenance and system expansion.

III. The main functions of the application of PHP technology.

This system can generate static HTML files for all the contents of the website, which can greatly save host resources and improve system performance. Full static processing technology is a necessary condition for building large-scale sites. Different users can choose different background operation interface, and users can make the background interface themselves, and then add it to the background interface management.

(1) integrate the website function module. Some functional modules can set it in the background, but do not need it to appear on the page, but reference its function somewhere, so that users can modify the functional module casually without affecting the set page layout, which greatly reduces the cost of modifying the functional module.

(2) powerful template function. The system not only provides built-in template tag calls, but also provides tag extension function. With this feature, users can write their own functions, and then add tags in the background to get template parsing. It is generally used to display data outside the system, such as forum data, real-time display data for monitoring, and so on. Users can dynamically change the template without changing the function of the website, which will bring great convenience to the developers and maintenance personnel of the website.

IV. Background operation of website construction in the application of PHP technology.

(1) Design of the background function module of the website

1. User management: the user management module can define the rights of the user, the type of website the user owns, the domain name of the binding user's website, setting the usage time of the user's website, and so on. Through the user management function, different levels of users can be provided with different levels of service, so that the user's website can achieve different functions.

two。 Interface management: interface management module can achieve interface addition, online editing, deletion, parameter setting and so on. Through the interface management module, we can provide users with a good template, and assign the template 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 are available to all users, and user pictures are only for the user's own use. Picture management can add, modify and delete pictures. Through the picture management module, the space size of pictures uploaded by users can be controlled, the pictures of different users can be managed separately, and the pictures that can be used by most users can be uniformly managed in the same folder to achieve the purpose of saving server space, audit the pictures uploaded by users, and force the deletion of illegal or unhealthy user pictures.

4. Database management: the main functions of database management module are data backup, recovery, optimization and upgrade. All the websites established by using the automatic web page generation tool, their databases are put into a unified large database, so that a lot of data can be used for multiple user websites, greatly saving the space of the database, and each user can manage his own virtual database separately.

(2) Design of backstage function module for website management

1. Parameter system: mainly set the parameters of the website. Such as column name, column number, column type, template setting, website name, website keyword, website language, hiding and display of functional modules, modification of top area and bottom area. The parameter setting system enables 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.

two。 Website module management system: mainly to set the function of the website. For example, the order system is a very commonly used system on the website, and if you make it into a ready-made system, users only need to enter some parameters to set up the order system, and there is no need for users to write programs or display styles; counter settings enable users to choose the style and display position of the counter without worrying about the implementation details of the counter. The side module provides users with commonly used side functions, such as login system, on-site search system, log system, links, etc.; the advertisement management system makes it convenient for users to set advertisements and choose the style of advertisements on any page; users can switch multiple pictures according to time by using the picture wheel. The website module management system integrates the common functions of most websites, which can make users realize a powerful website construction only by typing without knowing how to make and program the website.
