Demystifying foreach Behavior with Public vs. Private Object Properties
Article Introduction：Foreach only accesses public attributes when traversing objects in PHP; 2. Protected and private attributes are not visible, even if you use foreach($thisas...) inside the class; 3. To customize the traversal behavior, you can implement the Iterator or IteratorAggregate interface; 4. To check the properties that include private and protected, you need to use the Reflection class; 5.get_object_vars() also only returns the public attributes under the current scope. Therefore, foreach's behavior is the embodiment of PHP encapsulation characteristics, and non-public attributes will not be traversed.

Fun with Array Interfaces
Article Introduction：Key Points
PHP's array interface allows programmers to simulate the characteristics of native data types in custom classes, similar to Python's methods. This enables custom classes to work like arrays and allows common array operations such as counting elements, looping through elements, and accessing elements through indexes.
An interface is like a contract for a class, specifying the methods that a class must contain. They allow encapsulation of implementation details and provide syntax sugar, thereby improving the readability and maintainability of the code. PHP provides a library of predefined interfaces that can implement these interfaces to make objects similar to arrays.
Countable, ArrayAccess and Iterator interfaces in PHP allow objects to pass cou respectively

How to create a helper php function in Laravel?
Article Introduction：There are three common ways to create auxiliary PHP functions in Laravel. 1. Use helpers.php file: Create Helpers.php in the app/ directory, write the function, add a path in the autoload.files of composer.json and run composerdump-autoload to implement global calls; 2. Use macroable features: add custom methods to existing Laravel classes such as Collection through the macro() method, which conforms to the framework design style; 3. Create service classes: suitable for complex logic, such as creating HelperService class encapsulation methods and through dependency injection or app

How do I access object properties and methods in PHP?
Article Introduction：To access object properties and methods in PHP, use the -> operator. If the properties or methods are private, they need to be obtained through public methods. The details are as follows: 1. After creating the object, use $object->property or $object->method() to access public properties and methods; 2. Private or protected members need to be accessed indirectly through public methods such as getter/setter; 3. Static properties and methods are directly accessed through class name::. Mastering these rules can effectively avoid misuse of operators and implement encapsulation and control of data.

How to access a global variable inside a PHP function?
Article Introduction：To access global variables in PHP, you need to use the global keyword or $GLOBALS array. Use the global keyword to declare global variables in a function, such as: global$var;, which is suitable for situations where there are fewer variables, which have intuitive advantages but are prone to pollution; while the $GLOBALS array is directly accessed through $GLOBALS['var'], without declaration, suitable for multivariables but poor readability. It is recommended to avoid abuse of global variables to reduce maintenance difficulties and pay attention to naming conflicts. It is recommended to replace them with parameter passing or class encapsulation.

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.
