As the title states, PHP calls static methods directly using class names. There are two problems:
1 Will the constructor of the current class be called?
2 Will the constructor of the parent class of the current class be called?
You should test it yourself, the browser is the best teacherExample 1:<?phpclass A{
function __construct(){echo"A::构造函数";} static function myFun(){echo "你好,很高兴为你答题!";}
}A::myFun();?>Example 2:<?phpclass A{
function __construct(){echo"A::构造函数";}
}class B extends A{
static function myFun(){echo "你好,很高兴为你答题!";}
}B::myFun();?>
1. No 2. No
The constructor is only called during instantiation. Static methods do not generate instances and will not call the constructor
No, the constructor method will only be called when a class is instantiated. Static methods are stored in the static code area and are loaded as the class is loaded.
