PHP Parent Method Call Guide
In PHP, you can use the keyword parent:: to reference a method in the parent class. For example, calling a method from the parent class in a subclass can be done like this:
class ParentClass {
public function parentMethod() {
echo "This is parent method";
}
}
class ChildClass extends ParentClass {
public function childMethod() {
parent::parentMethod();
}
}
$child = new ChildClass();
$child->childMethod(); //输出:This is parent method
Call the parentMethod() method of the parent class in a subclass method using parent::parentMethod().
