3. 使用`static`关键字调用静态方法: “`php class MyClass { public static function myMethod() { echo “Hello, World!”; } public static function myOtherMethod() { static::myMethod(); // 调用静态方法myMethod } } class MyDerivedClass extends MyClass { public static function myMethod() {...
type the class name,scope resolution operator(double colons, ::), and the method name. To reference static members inside a class, the member must be prefixed with the self keyword followed by the scope resolution operator (::).
class MyClass { public static function myMethod() { echo “Hello, World!”; } } MyClass::myMethod(); // 输出:Hello, World! “` 2. 在类外部调用静态方法: “`php class MyClass { public static function myMethod() { echo “Hello, World!”; } } MyClass::myMethod(); // 输出:Hel...
