Article Introduction：There are three main ways to create custom verification rules in Laravel, suitable for different scenarios. 1. Use Rule class to create reusable verification logic: generate a class through phpartisanmake:ruleValidPhoneNumber, and introduce and use it in the controller, suitable for complex and reusable situations; 2.

Add custom rules in FormRequest: add closures or introduce Rule classes in the rules() method of form requests, which are clear and easy to manage; in addition, you can also use att

Article Introduction：There are three main ways to implement Singleton mode in Python: 1. Use a decorator to control the creation and reuse of class instances by defining closure functions. The advantages are that the code is clear and reusable, but the debugging is not intuitive enough; 2. Rewrite the \_\_new\_\_ method to maintain the instances within the class. The advantages are more native and object-oriented, but pay attention to multi-threaded safety issues; 3. Use the natural singleton characteristics of the module to directly create instances in the module and export and use them, which is simple and easy to maintain but poor flexibility. Choose the appropriate method according to actual needs: flexibly control the selection of decorators, object-oriented selection of \_\_new\_\_, and use the modules simply globally.

Article Introduction：To make Python code easy to maintain and adapt to future changes, the key is to have clear structure, simple logic and follow common specifications. First, we must make clear responsibilities, modular design, split different functions into independent functions or classes, each function only does one thing, each class is only responsible for one type of behavior; second, we must control the length of the function to be within 20 lines, avoid excessive nesting, reduce coupling between classes, and give priority to combination rather than inheritance; third, we must have clear names, use nouns (such as user_list), function names start with verbs (such as save_user_to_db()), class names use big camels (such as DataProcessor), avoid abbreviations to improve readability; fourth, we must use type prompts and document strings reasonably, and add detailed do for each function

Article Introduction：How to use PHP to get the number of days in a certain month? 1. Use the cal_days_in_month function, which is the most direct way. The syntax is cal_days_in_month(CAL_GREGORIAN, $month, $year); 2. Use the DateTime class and modify method to create the first day of the month and get the date of the last day by adding one month and subtracting one day. Both methods can correctly obtain the number of days. The former is simple and suitable for simple needs, while the latter is suitable for scenarios where DateTime operations are already available or requires more time to process.

Article Introduction：The key to PHP regular expression performance optimization is to reduce the number of backtracking and matches; 1. Avoid greedy matching and backtracking, use non-greedy patterns, avoid nested quantifiers, and reduce the use of capture groups; 2. Compile regular expressions in advance, and use static variables or class constant storage to reduce the overhead of repeated parsing; 3. Prioritize string functions to replace simple matching tasks, such as strpos, substr, etc. to improve efficiency; 4. Use anchor points and boundary control characters such as ^, $, and \b to limit the matching range to speed up the engine judgment.

Article Introduction：I'm having a tricky problem when doing a mail marketing campaign: how to efficiently create and send mail in HTML format. The traditional approach is to write code manually and send emails using an SMTP server, but this is not only time consuming, but also error-prone. After trying multiple solutions, I discovered DUWA.io, a simple and easy-to-use RESTAPI that helps me create and send HTML mail quickly. To further simplify the development process, I decided to use Composer to install and manage DUWA.io's PHP library - captaindoe/duwa.
