file collection cycle

The garbage collection mechanism of PHP features-the collection cycle is traditionally like the reference counting memory mechanism used by php in the past, which cannot handle cyclic reference memory leakage. However, 5.3.0 PHP uses the article»

The previous article introduced. the basic principles of net garbage collection and the internal mechanism of implementing the Finalize method for garbage collection; this article describes weak reference objects, generation, and multi-thread

Weak References: when the root object of a program points to an object, this object is reachable and cannot be recycled by the garbage collector, which is called a strong reference to the object. Strong references are relatively weak references.

1. The meaning of garbage collectionIn C + +, the memory occupied by an object is occupied until the end of the program and cannot be assigned to other objects until it is explicitly released, whereas in Java the memory becomes garbage when there is

1. Related ConceptsBasic recycling Algorithm Reference Counting)The old recycling algorithm. The principle is that this object has a reference, that is, adding a count. deleting a reference reduces the count. During garbage collection, only
