It mainly depends on how you use it. "*" can be used as a parameter, and php will generate a random number and then replace it

But if you change the value of class, is there really no problem with your page style?

This is applied within the article, such as every sentence and every paragraph, mainly to prevent crawler collection.

I wonder if you can explain it in detail. Thank you very much.

What should I say? Because I don't know how to replace this "*" specifically, it seems a little troublesome to implement in PHP. JS is easy to operate. You can directly select all spans and use traversal and classList.add (parameter). You can randomly generate this parameter.

Based on your tips, I found a piece of code that can be implemented. Thank you for your help. Thank you.
