Demystifying PHP's Magic Constants for Context-Aware Applications
Article Introduction：The seven magic constants of PHP are __LINE__, __FILE__, __DIR__, __FUNCTION__, __CLASS__, __TRAIT__, __METHOD__, and they can dynamically return code location and context information, 1. LINE returns the current line number, for precise debugging; 2. FILE returns the absolute path of the current file, often used to reliably introduce files or define root directory; 3. DIR returns the directory where the current file is located, which is clearer and more efficient than dirname (__FILE__); 4. FUNCTION returns the current function name, suitable for function-level log tracking; 5. CLASS returns the current class name (including namespace), in logs and factories

How to use collections in Laravel?
Article Introduction：Laravel collection is an advanced encapsulation of PHP arrays, providing chained calling methods to process data. It is implemented through the Illuminate\Support\Collection class, simplifying filtering, mapping, sorting and other operations. For example, filtering users older than 25 and sorting by name requires only one line of code. Common uses include: 1. Create a collection through collect() function or model query; 2. Use map(), filter(), pluck() and other methods to process data; 3. Support chain calls to improve code readability; 4. Pay attention to collection immutability, return value type and how to use it in Blade templates. Mastering these techniques can significantly improve development efficiency.

What is Eloquent ORM in Laravel?
Article Introduction：EloquentORM is Laravel's built-in object relational mapping system. It operates the database through PHP syntax instead of native SQL, making the code more concise and easy to maintain; 1. Each data table corresponds to a model class, and each record exists as a model instance; 2. Adopt active record mode, and the model instance can be saved or updated by itself; 3. Support batch assignment, and the $fillable attribute needs to be defined in the model to ensure security; 4. Provide strong relationship support, such as one-to-one, one-to-many, many-to-many, etc., and you can access the associated data through method calls; 5. Integrated query constructor, where, orderBy and other methods can be called chained to build queries; 6. Support accessors and modifiers, which can format the number when obtaining or setting attributes.
