[RESOLVED] Build one drop-down from 2 arrays

[zzz]

I have two arrays:

<?
$arr1 = array("CA","FR","GB","IT","US");


$arr2 = array("AU","CA","CO","DE","DK","ES","GB","IL","IN","IT","NO","PA","US","ZA");

How can I build dynamically a drop down menu from the two arrays above without duplicates? Normally I would use just one array and do something like

echo '<select>';

    foreach ($arr as $key => $value){ 
		echo '<option value="'.$value.'"';

			if ($myVar == $value) {
				echo " selected";
			}
		echo ">".$arr[$value].""; 
  	}
echo '</select>';

why not join the arrays and remove the duplicates first using array_unique

Do what dagon said:

$arr = array_unique(array_merge($arr1, $arr2));

Alternatively, if you wanted to do it so you knew which ones weren't duplicates, you could do this:

$add = array_diff($arr1, $arr2);
$arr = array_merge($arr2, $add);

Both achieve the same effect.

Cool. That's exactly what I'll do.
