Thanks for creating those videos. I really enjoy them. By the way, I wonder if this code has a race condition? I don't know PHP well enough, but I know the Singleton pattern and from what I remember, when you are creating the object, I would use a lock to make sure no other thread can create a new instance. Again, I am not familiar enough with PHP to know for sure.

HI, a thing I don't understand: everytime we run the get_instance() method, the $instance array is reset ( static $instance = [ ] )
how can $instance [ '$called_class' ] could even exists??

[ahmednabil-wbuj]

U put the following line inside get_instance function: static $instances = [];. But why it does not make the array empty every time u call get_instance ?

If there is a constructor, as you did for User, couldn't I just break the pattern by calling new User() ???
