The assignment operator in PHP performs different actions on different data types. First, explain the behavior of the value assignment operator =.

is the Unix filename and the file itself-the variable name is the directory entry, and the variable content is the file itself. References can be seen as tight connections in Unix file systems. A little explanation of what "references are": int i = 0; int j = 0; int *p = i; p = j; In the above code, p is a pointer to the memory address of I, and *p is the content, and the p=j point changes the direction of the P pointer, and the *P=111 expression changes the contents of I.

Conclusion 1: as long as one Nat is full cone Nat, bidirectional communication can be realized.Conclusion 2: as long as the nat on both sides are not classified as Nat, two-way communication is also possible. In other words, as long as the nat on both sides belong to the cone Nat, two-way communication can be achieved.Conclusion 3: Nat on one side belongs to the elastic Ric Nat, and Nat on the other side belongs to the restricted cone, which can also be used for bidirectional communication.Concl
