Use environment: there is a resume confidentiality setting in the talent network project, in which there is a filtering keyword, and only one of the keywords in the company name of an enterprise will not be displayed. Of course, I haven't been there yet. Now it's time to add and delete keywords.

Imagine: no matter how many resumes a person has, all resumes are set to the same keyword filter (few people mainly use them, so it doesn't matter, and it's convenient to search). Then put all the keywords into a string separated by a half-width comma.

Conundrum: when displaying, I convert the string into an array and then loop it out to display, but now I just want to delete the specified keyword.

Solution: now that it has been converted into an array, then there is a key if there is a value, so I will pass the key to the delete page and delete the value of the specified key.
