PHP表单 - 如果选择了2个单选按钮

I have a very simple HTML form on a PHP page for a questionnaire.

10 yes/no questions. Radio buttons.

I am trying to figure out how to show a hidden div if any 2 of the radio buttons are set to 'yes'.

would i be better off using a jquery script, or PHP?

    PHP could only do it if you roundtrip the form through the server after every button click, which'd still require Javascript to detect the click and submit the form for revamping.

    Remember that PHP runs on the server. By the time the user sees the form and is clicking around on it, PHP has long since completed its job and has shut down.

    In other words, you need to use Javascript for this.
