How to implement the marking and filtering functions of the accounting system - using PHP to develop marking and filtering methods requires specific code examples
Introduction:
With the development of society With the progress of the economy and the improvement of living standards, people are paying more and more attention to the management of personal finances. Bookkeeping systems have become one of the most important tools for managing personal finances. Among them, the marking and filtering functions are crucial for users. This article will introduce how to use PHP to develop the marking and filtering functions of the accounting system and provide code examples.
1. Implementation of the marking function
The marking function can help users classify and archive accounts to facilitate subsequent inquiries and statistics. The following are the specific steps to use PHP to develop tagging functions:
- Create a database table
First, we need to create a database table for storing accounting information. MySQL or other relational databases can be used to store data. The table structure should contain at least the following fields: id (unique identifier), category (accounting category), amount (amount), date (date), remark (remarks), etc. - Add mark field
Add a field for marking in the database table, such as mark, using a Boolean type to indicate whether it has been marked. By default, all accounts have their flag fields set to 0, meaning they are not flagged. - Implement the marking function
On the user interface of the accounting system, a "mark" button or check box can be provided for each account. When the user clicks the "Mark" button, the PHP code will update the corresponding account's Mark field in the database.
The following is a simple code example for updating the marked fields of accounts in the database:
<?php // 获取账目ID $accountId = $_GET['id']; // 更新标记字段为1 $query = "UPDATE accounts SET mark = 1 WHERE id = $accountId"; $result = mysqli_query($connection, $query); if ($result) { echo "账目已成功标记"; } else { echo "标记失败,请稍后再试"; } ?>
2. Implementation of filtering function
The filtering function can help users based on Retrieve accounts under specific conditions to achieve more detailed data analysis and management. The following are the specific steps to use PHP to develop the filtering function:
- Create a filtering form
On the user interface of the accounting system, a form for filtering can be provided, including various filtering conditions. For example, date range, amount range, category, etc. Users can select corresponding filtering conditions according to their own needs. - Processing filter results
Use PHP code to process the filter conditions submitted by the user, and query the corresponding account records in the database according to the conditions.
The following is a simple code example for filtering accounts based on a user-selected date range:
<?php // 获取用户提交的日期范围 $startDate = $_GET['start']; $endDate = $_GET['end']; // 查询符合日期范围条件的账目 $query = "SELECT * FROM accounts WHERE date BETWEEN '$startDate' AND '$endDate'"; $result = mysqli_query($connection, $query); // 输出筛选结果 if (mysqli_num_rows($result) > 0) { while ($row = mysqli_fetch_assoc($result)) { // 输出账目记录 } } else { echo "没有符合条件的账目记录"; } ?>
Summary:
With the above steps, we can implement an accounting system tagging and filtering capabilities. The marking function can help users classify and archive accounts, and the filtering function can make it easier for users to retrieve and analyze account data. When using PHP to develop tagging and filtering functions, we need to create database tables, add corresponding fields, and write corresponding PHP code to implement the functions. The above code examples are only simple demonstrations. In actual situations, they need to be modified and optimized according to specific needs. I hope this article will be helpful to implement the marking and filtering functions of the accounting system using PHP.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
