Pros to use any popular php framework for my one page website? [closed]

[nifox]

I've read the question Reasons to NOT use a PHP Framework? and googled before asking my question.The whole web-site is a one page only, that contains tne only textarea. The content of the textarea stored into the mysql db table every minute using ajax.Also, jQuery would be used for some reason.Are there any pros to use a framework?P.S.I should clean the text from POST user types before inserting it into MySQL db.The project is not going to be expanded or updated in the nearest future - it is a one page project.
