How to rank (prioritize) values from numbered checkbox form in PHP

I am using the code below to ask users to rank which programming language they are more comfortable with. The users need to rank from 1-3 (1 being the one they are most comfortable with)

<form id="form1" name="form1" method="post" action="">
<input type="number" name="php" required="required" max="3" min="1"/>PHP     <br />
<input type="number" name="python" required="required" max="3" min="1"/>Python <br />
<input type="number" name="ruby" required="required" max="3" min="1"/>Ruby <br /><br />
<input type="submit" name="button" id="button" value="Submit" />
</form>

Once the user prioritizes the programming languages and hits submit, how can I on the next page echo the ranking selection? (e.g. Your first choice is x, your second choice is y and your third choice is z)
