Thinking about looking at the tutorial, does PHP have something called ectopic or encryption? As shown in the picture, why can't I find it on Baidu?

It’s the one after $value

By the way, how do you type out the symbols? I looked at the keyboard for a long time and couldn't find anything that looked similar, so I couldn't even learn to write

The row of number keys above the letter keys on the keyboard is 6

Bitwise XOR operator

shift + numeric key 6 can type ^

if it is not in the small keyboard area

Bitwise operations, pay attention to point C, otherwise you won’t understand it even after I explain it.
