- PHP String Handling Functions
- Key Points PHP provides a large number of built-in string processing functions that can manipulate strings in various ways. These functions include changing the case of a string, finding the length of a string, replacing part of the string, and so on. Key functions include strlen(), str_replace(), strpos(), strtolower(), strtoupper(), and substr(). The trim() function in PHP can remove spaces at the beginning and end of a string or other specified characters, which helps to clean up user input before processing. The ltrim() and rtrim() functions perform similar operations, but only remove the left or right side of the string, respectively

- Understanding the Command Design Pattern
- Core points Command mode (also known as action mode or transaction mode) encapsulates requests into objects, allowing clients with different requests to queue or record. It is very useful for implementing command queues, where requests can be queued for sequential processing, while decoupling the actual implementation of execution from the queue itself. In scenarios where messages need to be sent to different user groups through different channels (email and text messages), the command mode provides a unified approach. It allows all customers to be retrieved from the database, regardless of the customer's communication preferences, to instantiate the appropriate IMessage implementations and process them at once, rather than repeating this process for each group. Command mode is ideal for the following situations: You want to execute

- Introduction to PhpDoc
- Core points PhpDoc (PhpDocumentor) is a powerful tool that helps developers write code documents through special format annotations. It can generate documents in multiple formats, such as HTML, PDF, and CHM, which can be extracted through a web interface or command line interface. PhpDoc uses DocBlocks (multi-line C-style comments) to document code blocks. DocBlocks contains three optional parts: a short description, a detailed description, and a tag. The tag starts with the @ symbol and specifies additional information about the code. The PhpDoc package is used to group relevant code elements in the generated document. You can use file-level or class-level

- Working with MySQL Events
- Core points The MySQL event, introduced since MySQL 5.1.6, is a time trigger that can be scheduled for one-time or periodic execution, providing an alternative to scheduled tasks and cron jobs. They can be used to create backups, delete obsolete records, or summarize report data, etc. The MySQL event scheduler is a background process that constantly searches for events to be executed. It can be started by issuing the command SET GLOBAL event_scheduler = ON; and it can be turned off by SET GLOBAL event_scheduler = OFF;. Its status can be in the MySQL process list

- The Liskov Substitution Principle
- Core points Liskov Substitution Principle (LSP) is a key concept in object-oriented programming that ensures that subclasses can replace their base class abstractions without breaking the contract with client code. It maintains the integrity of the system design and is crucial to the reusability of the code. When overriding a method in a subclass, certain requirements must be met: its signature must match the signature of the parent class; its prerequisites must be the same or weaker; its postconditions must be the same or stronger; and exceptions (if any) must be the same as the exception type thrown by the parent class. Breaking LSP can lead to unintelligible behavior and errors that are difficult to track. It also makes the code harder to maintain and extend, because the assumption that a subclass can replace its superclass is no longer true. Method rewriting does not always violate LSP
