This is the most exhaustive answer so far and gets rid of the need for a $i variable floating around. It is a combo of Kip and Gnarf's answers.

$array = array( 'cat' => 'meow', 'dog' => 'woof', 'cow' => 'moo', 'computer' => 'beep' );
foreach( array_keys( $array ) as $index=>$key ) {

    // display the current index + key + value
    echo $index . ':' . $key . $array[$key];

    // first index
    if ( $index == 0 ) {
        echo ' -- This is the first element in the associative array';
    }

    // last index
    if ( $index == count( $array ) - 1 ) {
        echo ' -- This is the last element in the associative array';
    }
    echo '
';
}

Hope it helps someone.
