well since this is the first google hit for this problem:

function mb_tell(&$msg) {
    if(count($msg) == 0) {
        return 0;
    }
    //prev($msg);
    $kv = each($msg);
    if(!prev($msg)) {
        end($msg);

        print_r($kv);
        return ($kv[0]+1);
    }
    print_r($kv);
    return ($kv[0]);
}

based on @fabien-snauwaert's answer but simplified if you do not need the original key

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

    // display the current index +  value
    echo $index . ':' . $value;

    // 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 '<br>';
}
