Get key value of associative array element in foreach loop

[jean-yves]

I have an array like this (test data):

animals = array(
"A"=>array("Aardvark"),
"B"=>array("Bee"),
"C"=>array("Cat"),
//etc...
);

Then I want to iterate through it to build an html select statement. Here's my code for within the select tags:

foreach($animals as $e)
echo("<option value='" . key($e) . "'>" . $e[0] . "</option>\n");

However, this always displays the key as 0 rather than "Aardvark" etc

Any ideas how to iterate through and set the value of each Option to Aardvark, Bee, Cat, in turn?

Thanks!

BTW: each of the sub arrays actually has several elements within it - I just show one for calrity

this is an example in my book, it may or may not help:

<?
$knicks = array (center => "Ewing", point => "Childs", shooting_quard => "Houston", forward => "Sprewell", strong_forward => "Johnson");

echo "<h2>The Knicks 1999 Starting Five Were</h2>";
while (list($key,$value) = each ($knicks))
{
     echo "$key: $value <br>";
}
?>

Thanks - works great! :-)

BTW: I would have replied earlier but couldn't find the reply button - Mozilla renders the page so wide that I suddenly realised that I had to scroll right to find it!
