Article Introduction：Analyzed the difference between static classes and static variable usage classes in PHP, created the object $object = new Class(), and then used "->" to call: $object->attribute/function, provided that the variable/method is accessible. Directly call the class method: class::attribute/function, whether it is static or non-static. Static static: declare a class member or method as static, you can access it directly without instantiating the class, and you cannot access it through an object. Static members (except static methods), static members belong to the class and do not belong to any object instance, but object instances of the class can be shared

Create an object $object = new Class(), and then use "-> "Call: $object->attribute/function, provided the variable/method is accessible. 2. Directly call class methods/variables: class::attribute/function, whether static or non-static. But there are prerequisites: A. If it is a variable, the variable needs to be accessible. B. If it is a method,

Article Introduction：Static member function Declaring the member function as static can separate the function from any specific object of the class. It can also be called when the class object does not exist. Just use the class name plus the range resolution operator:: Access·Static member functions can only access static member data, other static member functions and other functions outside the class

Article Introduction：The difference between static functions and class methods in C++: declaration method: static functions use the static keyword, and class methods are class member functions. Access method: Static functions are accessed through class names or scope resolution operators, and class methods are accessed through class object member access symbols. Data member access: Static functions cannot access class data members, but class methods can access all data members of the class. Purpose: Static functions are suitable for functions that have nothing to do with the class and do not need to access class state. Class methods are suitable for functions that need to access class data.

Article Introduction：PHP static class method refers to a static method defined in a class, which can be called directly without instantiating the class. Static methods can be understood as global methods because they are called at the class level rather than the object level. They can be called with the class name and a double colon. To define a static method, use the static keyword, as follows: ```class MyClass { public static function myStaticMethod() {

Article Introduction：The difference between dynamic classes and static classes in PHP: 1. Static classes are frequently used, and dynamic classes are rarely used; 2. Static classes are fast and occupy memory, while dynamic classes are relatively slower, but are released immediately after being called. You can save memory and choose according to your own needs; 3. For servers with larger memory, setting it to static will improve efficiency. Compared with servers with smaller memory, dynamic mode will end redundant processes and can recycle and release some memory. .
