Link To Specific Option Values - php

Question

I am trying to modify some code I found on this site (courtesy of mqchen) to enable linking to specific option values. Although it's close to what I'm looking for, I have little php knowledge and therefore need some help. Here's the original code:
<?php
$options = array('Norway', 'United States', 'Springfield');
echo '<select>';
foreach($options as $country) {
if(array_key_exists('selected', $_GET) && $_GET['selected'] === $country) {
echo '<option selected="selected">'.$country.'</option>';
}
else {
echo '<option>'.$country.'</option>';
}
}
echo '</select>';
?>
And the link would be something like:
/countries.html?country=norway
I need to have not only the country between the option tags, but also a value in the option tag, so that the final output would be:
<option value="unitedstates">United States</option>
I was also going to edit the third line to:
echo '<select name="name" size="1" onchange="ShowHide(this.value);">';
because my select tag currently has those attributes for certain functionality. So basically all I need to do, I believe, is add another array containing the option values that line up with the countries and put the variable into the option tag, which I assumed would be:
<option value="'.$valueid.'">
But I'm not exactly sure.

You should do
$options = array('norway' =>'Norway', 'unitedstates' => 'United States', 'springfield' => 'Springfield');
echo '<select name="name" size="1" onchange="ShowHide(this.value);">';
foreach($options as $key => $country) {
if(array_key_exists('selected', $_GET) && $_GET['selected'] === $country) {
echo '<option selected="selected" value="'.$key.' >'.$country.'</option>';
}
else {
echo '<option value="'.$key.'>'.$country.'</option>';
}
}
echo '</select>';
BTW - this is php not jQuery
