Why, the parent class method is executed in advance

Why, the parent class method is executed in advance.


------Solution--------------------
PARENT::FUC () is echo ... in Luo::fuc ().
does not return a string
and echo Self:: $name 1. '---------'. PARENT::FUC ();
Wait until the string assembly is complete before it is output, and naturally you feel like you're doing it ahead of time.
------Solution--------------------
The Fuc method of the parent class is changed to this:
Public Function Fun () {
Return self:: $name ...;
}
------Solution--------------------
Direct output, unless you do not run to this piece of code ...
