Gaming Fansite Grab Info From Option, Put Into Variable

[RuneStation]

Keep in mind, I'm a bit new to coding so if this is a stupid question, I'm sorry!

If you've ever heard of the online game, RuneScape, you know there is a highscore database.
I know how to access that database by the code below:

Code: [Select]

$name = $_POST['name'];
$filecontents = file_get_contents("http://hiscore.runescape.com/index_lite.ws?player=$name");
$stats = explode(',' , $filecontents);
$exp =  explode("\n", $stats[specificLevel]);
echo $exp[0];
and it posts the results (what it found on that specific page, line) like this:

Code: [Select]

<input type="text" name="nameLevel" value="<?php echo $exp[0] ?>" />

What I Need:
I want to grab a specific level, based on what they choose in

Code: [Select]

<select name="skill" onchange="calculateLevels()">
<option>Farming</option>
<option>Hunter</option>
<option>Firemaking</option>
(only 3 for example)

So I'd like to grab, for example, Hunter, and insert a specific number as a variable (to correspond that certain level from the online database webpage) and insert that specific variable into the code of

Code: [Select]

$exp =  explode("\n", $stats[specificLevel]);
If any of this made sense, please offer your help.
If you need anymore information, just ask .

Thanks!
