want to make a copy of the object, and you want the original object to change without affecting the copy. For this purpose, PHP defines a special method called __clone.the role of referencesIf the program is larger, referencing the same object is more variable, and you want to use the object after the manual removal of it, the personal suggestion "" method, and then $var=null to clear.

You can also write an absolute path:/**/lib (tried!) ）Test.java refers to the class that contains the m

This qualification is meaningful and cannot be directly assigned to Ival, so it is not possible to modify the ival by Refval;After the const qualificatio

Php introduces the garbage collection mechanism by referencing counters. PHP has a very simple garbage collector, which will actually collect garbage for objects that are no longer in the scope of memory. The internal method of garbage collection is to use a reference Meter.

conmunication (){....}} He said that dynamic reference can save resources by referencing this file only when this method is used, so the server pressure will be reduced.However, I think it is very troublesome to write such a statement. it is often necessary to write three sentences in the result of a sentence. C # and JAVA are not written in this way. code redundancy is annoying. Will the image performance be high? Or do you have to worry about i
