Class (2)-deconstruct function and garbage collection, deconstruct garbage collection After defining a class, we can create any number of objects. In this case, the memory allocation on the managed heap and stack will be generated, and a new space will be opened in the heap to store class objects, while the stack will

Objective PHP is a managed language, in PHP programming programmers do not need to manually handle the allocation and release of memory resources (using C to write PHP or Zend extensions), which means that PHP itself implements the garbage collection mechanism (garbage Collection). Now if you go to PHP official website

1 . For GC, when a programmer creates an object, the GC starts to monitor the address, size, and usage of the object.Typically, a GC uses a graph to record and manage all objects in the heap. In this way, you determine which objects are "accessible" and which objects are "unreachable." When the GC determines that some objects are unreachable, it is the responsibility of the GC to reclaim those memory spaces.2, can. The programmer can manually execute System.GC () to notify the GC to run, but the
