"Select Multiple", retrieving array values on next page, PHP

The below code creates an array called "skills[]" and sends to page2.php .

<form action=page2.php method=get>
<select name="skills[]" multiple>

<option value="degree">IT DEGREE</option>
<option value="msce">MSCE</option>
<option value="fas">FAS</option>
<option value="diploma">IT DIPLOMA</option>
<option value="msoffice">MS OFFICE</option>
<option value="linux">LINUX</option>

</select>
<input type=submit>
</form>

The querystring is ".../page2.php?skills%5B%5D=msce&skills%5B%5D=fas" if MSCE and FAS are selected, for example. Problem is i dont know how to access the elements. Google only has examples of sending to the same page and i cant figure out how to adapt them. does anyone know how i can display a list of everything in the array on the following page? i tried

foreach ($_GET['skills'] as $k => $v)
        {
        echo $skills[$k] . " : " . $skills[$v] ."<br>";
        }

but its not workin.




/EDIT: actually, it works if i do this:

$num=count($_GET['skills']);
echo "You selected " .$num ." choices<br>";
for ($i = 0 ; $i < $num ; $i++)
        {
        echo $_GET['skills'][$i] ."<br>";
        }

thanks anyway.
