The role of PHP technology application in website development embodies _php tutorial

First, Introduction

The use of PHP technology to develop the automatic Web page generation tool, not only can be used as a self-help station platform, but also as a website management system. Its data update to a large extent to meet the user's "personalized needs", that is, in the content and style close to the user's thinking, the system is fully graphical visualization, even if you do not know how to make Web pages of specialized technology, do not understand the HTML language, through the system such as columns, template settings, website keywords, function modules, etc. Users can also use it to easily create ever-changing, color-rich websites.

Second, the system's main development tools and the use of related technologies

(a) System Development tools PHP Introduction

PHP is the abbreviation for hypertext preprocessor, which is hypertext preprocessing. PHP can be embedded in HTML, simple language, easy to master, cross-platform support, portable, can be run under Linux, UNIX or Windows operating system, support IIS, Apache and other popular web server; PHP source code is completely public free; PHP built-in database support, access to a number of mainstream databases, such as Oracle, MSSQL, Dbase, Sybase, Informix, MySQL, and so on, when the Web server to withstand the great demand, PHP performance is still stable, there will be no performance dips in the situation; PHP has powerful text processing capabilities that support POSIX extensions, Perl regular expressions, and XML document parsing.

Two Key technologies used in PHP technology applications

1. Template technology. Template technology is a developer pre-designed a number of commonly used framework structure, the page according to the type of function classification, summed up the commonly used page type, generate Template Library, users can import, export and management of website style, website use which style, just click Set as the default website style can, and do not have to re-build, It saves the user's development time and facilitates the user's use.

2. Label Technology. The labeling of the action function can be used to encapsulate the display function of the page in the page, which makes the whole page more concise and user-friendly, code reuse, code maintenance and easy system expansion.

Third, the main function of PHP technology application system

The system can generate static HTML files, which can greatly save the host resources, improve system performance, full-static processing technology is to build a large-scale site requirements. Different users can choose different background operation interface, and users can create their own background interface, and then add to the background interface management.

(i) Integrated website function module. Some functional modules can be set up in the background, but do not need it to actually appear in the page, but in a place to reference its function, so that users can casually modify the function module without affecting the layout of the page, which greatly reduces the cost of modifying the function module.

(b) powerful template function. The system provides not only the built-in template tag invocation, but also the label extension feature. With this feature, users can write their own functions, and then add tags in the background, you can get template parsing. Generally used to display data outside the system, such as: forum data, real-time display data for monitoring and so on. Users can not change the functionality of the site, the dynamic Change template, will give the site developers and maintenance personnel to bring great convenience.

Iv. the background operation of website construction in PHP technology application

(a) Website backstage function module design

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

2. Interface Management: Interface Management module can be added to the interface, online editing, deletion, parameter settings and so on. Through the interface Management module, can provide the user with the production of good template, and according to the needs of different users to assign templates to users.

3. Image management: Image management is divided into system image management and user image management. The system picture is available to all users, and the user picture is used only for that user. Picture Management allows you to add, modify, and delete images. Through the image management module, you can control the size of the user to upload pictures, separate the different users of the picture management, the majority of users can use the picture into the same folder to achieve the purpose of saving server space, audit users upload pictures, and can forcibly delete illegal or unhealthy user pictures.

4. Database management: The main function of database management module is data backup, recovery, optimization, upgrade. All Web sites built using Web-based auto-generation tools, their databases are placed in a single large database, so that a lot of data can be used for multiple user sites, greatly saving the space of the database, and each user can manage their own virtual database.

(ii) Website Management backstage function module design

1. Parameter system: Main Setting the parameters of the website. such as the name of the column, the number of columns, the type of column, template settings, site name, website keywords, site language, function module hidden and display, the top area and the bottom area of the changes. Parameter setting system can make the user to build a basic frame of the website in the shortest time, after the parameter setting, can say a website basically formed.

2. Website Module Management System: The main function is to set up the website. If the order system is a very common site system, make it a ready-made system, users only need to input some parameters can be set up the order system, no need to write programs or write the display style; Counter settings enable the user to select the style and display position of the counter, not to worry about the implementation details of the counter; Side-side module to provide users with common side functions, such as login system, station search system, log system, links and so on; The advertisement management system is convenient for users to set up ads on any page, choose the style of advertising, etc. users can switch to multiple images based on time using the picture rotation device. Web site module Management system to most of the common functions of the site integration, you can make the user at all without website production programming premise, just by typing can achieve a powerful website construction.

V. Concluding remarks

The Web page auto-generation tool using PHP technology can not only be used as a platform for self-service building, but also as a website management system. Through the template customization, you can apply a specially designed page template, so that users have their own characteristics of the site at the same time, with a variety of dynamic management functions, so that only the text input of non-professional technical personnel can also quickly and efficiently complete their own web pages, so as to achieve self-help building, management and update the site, This will certainly make our country's informatization construction process get greatly improved.
