Does this have to be php? It sounds more like a js solution.

<form id="cv" action="" method="">
    Choose Option: 
    <select id="chedo">
        <option value="">--Choose Value--</option>
        <option value="1">A</option>
        <option value="2">B</option>
        <option value="3">C</option>
    </select>

You can't run php on a loaded page, unless you use Ajax. So it's js unless you want to reload the page every time you select an option
