What is the use of bitwise operations? Okay, this is a boring problem. it seems that I have never seen such operators in PHP code. Who can give an example of the situation where & lt; & gt; ^ bitwise operators are used, or what scenarios are suitable for them. ------ Solution -------------------- in addition to encryption verification, status permission parity verification, and so on, it seems that there is no other use! For example, is it really necessary to change the variable value to php? What is the use of bitwise operations that can save?
