With the rapid development of Internet technology and the rapid popularization of electronic equipment in the world, the network has entered people’s lives with computers, mobile phones and other devices. Currently, there are a large number of issues in the construction and application of campus websites in China, such as inconvenient interaction, low information credibility, inadequate technical functions, and unequal demand and technology. Therefore, our primary issue is how to build a website that is easy to operate and has a clean interface.
1、 Development environment analysis and issues
1. Selection of software language and problem analysis. The three mainstream languages for network development now are ASP NET, PHP, JSP, all have their own uniqueness and advantages and disadvantages. JSP has good compatibility, best security, expandable tags, and supports cross platform use, but it is difficult to proficiently use and has poor portability. PHP has good compatibility, good security, strong performance, simple coordination, and is easy to learn, but it has the problem of being single threaded; ASP. NET development is fast and easy to master, but it has poor compatibility and is only suitable for Microsoft servers. Its security is average and there are too many vulnerabilities, making it difficult to implement certain specific requirements. This project uses PHP as the development language. PHP, as a type of C language, has fast upward mobility in use, and supports cross platform services, superior performance, and simple syntax. Currently, most mainstream technologies support PHP. PHP, as an open-source source code, makes it highly versatile and has multiple frameworks that can be used; As a widely used website construction language, security has been widely recognized by most people.
2. Selection of programming software. The current web programming software on the market
It is also full of features, such as Sublime, Editplus, Dreamweaver, Zend Studio, etc. After comprehensive analysis of various factors, Zend Studio was selected as the programming software. Zend Studio is a software designed specifically for PHP website development, featuring function highlighting, automatic error correction, function reminders, and most notably, its function lookup feature. The function search is not limited to PHP and MSQL functions themselves, but also includes functions created by programmers themselves. After clicking the function with the left mouse button, the software automatically jumps to the function, which greatly facilitates page jumping and function error detection analysis in programming.
3. Environment setup software and problem analysis. The most commonly used software combination for PHP website development is WAMP (Windows+Apache+MYSQL+PHB). Apache is an open-source web server with good applicability and security. When selecting an integrated installation environment, on the network
There are many platforms available (Appsvev, PHPStudy, Wamp, etc.). Before using them, refer to many online reviews and finally choose to install Appsvev. Multiple installations have revealed significant issues with Appsvev during version 8.0 installation. The username and password for logging into the database were set during installation, but after completion, a login error occurred while accessing the localhost i webpage with the following error message: “Access denied for user root’localhost (using password: YEs)”. The problem is that the root user cannot be accessed and the password used is correct. Upon checking the user login file in MYSQL, it was found that the user and password fields were not written into the base file. After discovering that it was an error in the base file, multiple software reinstallations were performed, but the above problem persisted. Finally, MYSQL was set to not check the user password for login. In terms of multi computer authentication, MySL is widely used The method of logging in without checking the user password appears on some computers, which can only be logged in once. If you try to log in again, the message ‘login failed’ and ‘root user not allowed’ will appear. And this method greatly reduces the security of the database, which may cause incalculable losses to subsequent development. In the end, the project abandoned the use of Apsr’s integrated environment. After comparing and installing in multiple integrated environments, we ultimately chose PHPStudy as the development environment. It is easy to install, free of software fees, and saves development costs. Multiple installations were successful and the database connection was normal. When not using the local database, the entire integrated environment can be shut down to save the backend resources of the computer itself. The database password and username are directly set in the basic file, which may lack humanization but avoids the problem of being unable to log in to the database in Appsorvi.
2、 Functional module design and problem analysis
The main function of this website is to publish and exchange information. So the main functional modules implemented are: login module, information publishing and processing module, Tieba style communication module, etc.
1. In the implementation of each module, we strive to simplify the code as much as possible, so we use many functions to achieve the same function on different web pages, which can simplify the code and backend compilation time. For example, addinfo is set as a function to add information, and both administrators and regular users have permission to publish information Write the specific implementation steps of Adolfo in inc and PHP, and directly call the function in the implemented webpage to insert information into the database.
2. Considering that the information publishing platform involves many aspects, including the sharing of images and files, and each implementation requires a certain period of time, we adopt the Kinderditor integrated environment. Kiindeditor flexibly uses tags<span to implement front-end data, with good compatibility with mainstream browsers such as E, Firefox, Chrome Satan, Operas, etc. As an open-source HIML visual editor, it brings great convenience to programmers. This integration module can be directly called in the code, and the implemented functions include single image upload, multiple image upload, general Word document upload, emoticons, and related processing of text formats. Such direct calls not only reduce the implementation cycle of the project but also ensure the user’s functional implementation. 3. Verification codes are set on the webpage in the login module to prevent users from using robots to automatically register, log in, and other malicious behaviors. During the login process, considering the difficulty in distinguishing some similar characters during user experience, we manually delete the numbers 01, 2, and the letters o1, qO, and Z when selecting characters to prevent these difficult to distinguish characters from appearing during the verification process. We first create a canvas of a specified size, then use a character generation function to randomly generate a combination of four digits and letters, and then pass the whole to the front-end display webpage to display the verification code.
The Tieba style communication module is also a relatively novel aspect of the website. We first combined the functions of the information publishing module in this module, where users can write their relevant knowledge while viewing the theme posts. We have created a table in the database (tb note) to include the content of these reply posts. [content] records the specific content of reply messages, name records the user name of reply messages, and scnd records reply messages
At the time of rest, Pidi records the content of which main post the reply post belongs to. The use of PID retrieves all replies regarding this main post information.
3、 Information synchronization and problem analysis
PHP mostly uses form tags for data submission on front-end web pages, and calls the insert function to complete data writing. The information submitted in the front-end is usually an array passed in the form of a post. Taking registered users as an example, users without accounts can achieve more functions provided by the website by registering as users. The information required for registration includes username, password, major, class, etc. We will input the submitted information into the database in the form of an array. This can easily lead to some problems.
1. The data names in the array do not correspond. In the front-end webpage, we need to give each incoming data a corresponding name that must be strictly consistent with the fields in the database. If the name of one of the data does not correspond to the entire array, the write cannot be completed. When problems arise, more debugging work should be done to verify step by step where the error occurred. For example, using print r to print an array displays the name of the passed array as the corresponding value, and using the f function to determine which step of the function has a null value during execution.
2. Arrays cannot correspond one-to-one. In the transmission array, it is required that the fields of the front-end transmission array correspond exactly to the fields of the database table. In the registration webpage, it is necessary to repeatedly enter the password twice. The transmitted array has an additional verification password value, and without cleaning the array password verification value, the data cannot be inserted into the table. Set debugging points in the reg registration function for debugging. During the debugging process, it was found that setting the password verification value to null or 0 could not submit information. Finally, the unseti function in PHP was borrowed to clear the data.
The problems and functional analysis encountered in building an information publishing platform using PHP website mainly involve the selection of programming language, environment setup, and problem solving of functional implementation. The online platform provides a good platform for students to integrate and process information.
