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

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

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

reply 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.
